OTC's Newest Automotive Diagnostic Scan Tool - Pegisys

OTC's Newest Automotive Diagnostic Scan Tool - Pegisys

Genisys has been a very popular choice in auto scan tools for many years, but now Pegisys is staged to be OTC's next generation of automotive diagnostic scan tools. Genisys is still a very good scan tool and will continue to be very popular due to it's much lower cost and it will continue to be supported by OTC. OTC has many automotive code readers, scan tools and diagnostic tools. OTC currently has the OTC 3499 (no fancy name), the Nemisys, the Genisys and now the Pegisys. The Pegisys has AirBridge technology which allows wireless communication with the vehicle and the Internet. I suppose there is a correlation between the Pegisys and Pegasus, Pegasus is a winged horse in classical mythology and is also a northern constellation between Cygnus and Aquarius. It represents the freedom of the wireless capability that allows the auto tech to move around the vehicle when performing diagnostic tests. Auto scan tools normally have an interface cable that keeps the tech in the seat or requires the cable to be draped through the door or window to reach the engine compartment.

Pegisys has a touch screen. In addition to being able to use the scroll to change frames when using the scan tool, the Pegisys allows the user to make selections right on the touch screen. Everyone knows that guys are "visual" creatures. So, what better way for a guy to find the application he wants than to just touch the image on the screen?

OTC 3825 equipped with a scope. Sometimes when testing a particular component on a car, a scope is needed to see the wave patterns to help detect momentary glitches. This is particularly helpful when testing sensors like the TPS (Throttle Position Sensor).

Updates through the Internet. The Pegisys comes with a one year subscription that starts when the tool is registered for warranty on the Pegisys website. It comes with USA Domestic and Asian software and even has OBD I and OBD II cables included. Optional software enables the Pegisys to be used on European vehicles and Heavy duty truck applications.

OTC also produces car dealer specific diagnostic scan tools like the Tech 2 Scan tool for Chevrolet. While the Tech 2 has programming/flashing capability it is limited to GM. The key to the Pegisys scan tool is that it has the capability to access many different makes and many systems.

This makes the OTC Pegisys Scan Tool a good choice for repair shops that need to service many different makes and models. With access to the Internet, technicians can also easily find more information from Identifix an optional data base that has fixes that auto techs in the real shop environment have uploaded. Indentifix can of course be accessed without the Pegisys, but with the wireless Internet it just makes it very convenient.

A Backyard Mechanic's Guide to Troubleshooting a Diesel Engine

A Backyard Mechanic's Guide to Troubleshooting a Diesel Engine

You don't have to be a certified mechanic to troubleshoot a diesel engine. All you need is a bit of mechanical aptitude and some basic tools. You have to determine what happened right before the breakdown. This is called the story line, it's a blow by blow sequence of events that will help you determine the cause of the failure.

By the way, if your diesel engine is electronic you may find yourself towing it to a dealer who has a scanner to get the codes out of the On Board Diagnostics System. BUT there are still checks you can perform before you call the hook.

Always check the simple things first!

Diesel engines require air and fuel to run.

This is investigative information that will guide you to a possible solution. You have to ask the driver of the vehicle the following questions.

1. What was exactly going on when the engine quit?

2. Were there any dash gauges or warning lights acting up?

3. Were there any unusual noises?

This will help you get some clues on any contributing factors that could give you some troubleshooting wisdom. If the engine was hesitating or losing power you could be looking at air in the fuel. If the engine just quit instantly you should check the ignition system, fuel transfer pump and engine shutdown solenoid.

Here Are Some Basic Checks You can Follow up With: Mostly for a rough running engine condition before it quit.

1. Is the fuel tank topped up? I know this is a lame question but it's happened before.

2. Is there gas in the tank instead of diesel? Again, I've seen this happen before.

3. Check the fuel filter and make sure it is full of fuel. This determines if you have a fuel starvation problem or not.

4. Check for water in the fuel separator, the first filter closest to the tank. They have a bleed off valve at the bottom of the housing.

5. Check for fuel leaks at the lines and fittings.

6. Check the air filter for any restrictions. This won't cause a no start unless air intake is totally blocked off.

7. Make sure you are getting fuel to the injection pump. Crack a line before the injection pump and crank over the engine to determine if the fuel transfer pump is working.

8. Crack open an injector fuel line at one of the cylinders and crank over the engine.
Are there signs of pressure or a foamy substance? The latter means there is air in the fuel.

By this time you will have determined where the problem is in the fuel system. Once you nail down a general theory to what component is at fault you can do some digging and pick some brains at the local repair shop. These procedures will help you possibly find a problem along the way, get some experience and save a few bucks.

Computer Hard Drives - Hard Drive Problems and Symptoms

Computer Hard Drives - Hard Drive Problems and Symptoms

Is your hard drive acting up? Do you fear the loss of data, downtime, and possible loss of revenue this could bring? Let's take a look at diagnosing hard drive problems, and what the symptoms are.

The surest sign of a major problem is this: when you write data to the disk, and retrieve it later, errors pop up. It might take the form of small amounts of data going missing, or being turned into gibberish. If this happens in more than one program, disk failure looms in the very near future.

Some users "cure" this problem by reformatting the drive, then re-installing the OS and all programs. Unfortunately, this doesn't correct the root cause of the trouble, and it will only be a matter of time before it pops up again, perhaps fatally.

Strange noises, particularly high pitched squeaks, are often attributed to the hard drive. In the majority of cases, these squeaks aren't coming from the drive, but from a case fan, or power supply fan.

Listen closely with one of the side panels removed to zero in on the sound. If necessary, unplug the drive's power cable, then turn the computer on. If you still hear the squeak, you know it's a fan. But if the squeak goes away, only to return when you boot the hard drive, you have a very serious problem.

If your hard drive seems to be working too much, constantly chugging away, always sending data to and from RAM, the problem isn't your drive. The odds are you need more RAM. Today's giant programs are memory hogs, immense in size, creating multi-megabyte files.

If your hard drive is slowing down there are a number of different causes. These won't lead to disk failure, but they can be frustrating.

The first, and easiest to deal with, is drive fragmentation. In XP and Vista it's easy to defragment a drive, requiring only a few mouse clicks, yet most users let months go by without doing it. They wait until their machines have slowed to a crawl before performing this most basic act of computer maintenance.

Another cause is the volume of data stored there. The more data on the disk, the slower retrieval and write-to rates become. The cure is obvious. Either do a bit of house cleaning, removing unneeded files, or add another drive.

Sometimes, a sluggish hard drive can be a symptom of spyware, adware, or a virus. A good security program can scan your drive, and tell you if you have one of these problems.

"HDD Diagnostic" Virus Removal Guide

"HDD Diagnostic" Virus Removal Guide

HDD Diagnostic is another fake computer optimization program pretending to be a hard drive defragmenter. The application attempts to scare you by displaying fake detections of system errors and then will present you with a perfect solution for all problems that you are experiencing in your PC by purchasing a registration code that will unlock the full version of the program. This is a total scam because the full version will not do anything to improve the condition of your PC and all the problems that you have. The slowing down of your system, the blocking of your Internet settings and disabling of Task Manager are all caused by HDD Diagnostic Virus. You should remove this program to prevent further damage and infecting other computers. This tutorial will guide you to remove the infection from your PC.

HDD Diagnostic is a clever invention by hackers categorized as a "malware" program or malicious software that enters your system without your knowledge through the help of Trojans, via fake websites, rogue downloads and bogus e-mail attachments. The hackers who created the application use this tool to gain access to any personal information that you might have stored inside your computer. Aside from causing problems in your system and offering you false upgrades, the program keeps displaying error messages that prevent you from concentrating on your work. All program files of this application should be removed to get rid of the virus.

HDD Diagnostic Removal

This virus is basically a rogue piece of software, meaning that in order to get rid of it, you'll need to take several more steps than just using an antivirus application. You need to first stop the virus from running, and then delete all of its files. This can be done either manually (if you're confident with PCs), or automatically (which is recommended). Manual removal of the infection can be done by loading up your computer into "Safe Mode" and then deleting all of the files that it is using (listed below). If you're not sure what safe mode is, then it's strongly advised you use a reputable automated tool to fix the infection.

This virus will install its files here:

%Temp%\

The most reliable way of removing the HDD Diagnostic Virus is to use a trusted "anti-malware" program created by well known and legitimate software security firms that can scan through your system and delete all infected files. Our trials have led us to believe that the most effective tool in dealing with the HDD Diagnostic Virus is an application called "Frontline Rogue Remover" - a newly released tool which basically works to show you how to stop the virus from running before getting rd of it from your PC. You can use this tool by downloading it onto an uninfected PC and then following its 2-step process to fix your infected system for good.

Stay Away From 'Double Billing' When Engaged in This Radiology Procedure

Stay Away From 'Double Billing' When Engaged in This Radiology Procedure

After suffering a blow to the head, a patient showed the following symptoms - dizziness, sleepiness, slurred speech, and confusion. The doctor attending to the patient ordered a CT scan to check for internal injuries and aneurysm. After finding out that there was no evidence of serious injury, the doctor admitted the patient for observation.

Under such circumstances, can the physician biller bill for the interpretation?

The answer is no. The physician biller cannot bill for the interpretation. A facility radiologist or other physician may give interpretations for all ordered tests as a matter of policy in a hospital or other inpatient facility. As such, you being the admitting but not attending/ordering, physician's biller, you are not entitled to reporting the interpretation for 70460.

You need to ensure that only one person reads the diagnostic test and the person billing it should have an all-encompassing report. If your physician reads the films/fluoros and bills for them, then you should keep handy a separate note with a separate signature at the end of the op.

You probably could not report the CT scan interpretation for your doctor in the above scenario because, very likely, the hospital radiologist would prepare the initial report for the CT scan. Even when your doctor provides the immediate interpretation used for treatment and the radiologist provides an "over-read" (secondary quality assurance review), hospital rules may give the charge to the radiologist.

Conclusion: So if one physician has already interpreted a test and provided a report outlining the result, no other physician can bill for the same service. This would fall under the category of radiology procedure double-billing.

Case Study: Automotive Repair Industry Process Improvement

Case Study: Automotive Repair Industry Process Improvement

When customers think of automotive control modules, what comes to mind are engine control modules, transmission control modules, and body control modules. Some people are genuinely surprised to find there can be as many as 80-120 different control modules functioning in their vehicle, controlling everything from power windows to drive train components. As everyone in the industry knows, as fuel economy, emissions and safety become more important to shoppers; control modules will become even more important to a smooth operating automobile.

At the same time, the ability of repair shops to diagnose and repair control module problems is being challenged. Many shops do not have the proper scan tools needed to see deeply enough into the vehicle's control module network to determine what is really happening there. In these cases, the shop is forced to diagnose the vehicle with circumstantial information instead of with the actual observation of vehicle network data. This is equivalent to looking at a "boot print" of the problem instead of actually seeing the boot. This drives questions such as:

· How do I know that the module is really bad?

· If I replace the module, will the vehicle start working properly?

· What can cause the module to go bad?

This is both a challenge and an opportunity for repair shops and the replacement parts industry. Two aspects of customer satisfaction affect every business: satisfaction with the product and satisfaction with the service surrounding it. This is the premise underlying the processes we sat up for Automotive Electronic Solutions (AES) to use in its business of repairing and remanufacturing automotive control modules.

In the case of control modules, the "service surrounding the product" challenge is to understand that the shop first needs a quality diagnosis, before the subject of quality replacement parts can take place. For AES, this is a matter of determining what level of service best fits the customer's problem. Specifically, AES will ask about trouble codes and symptoms to determine the best solution for the customer. If the trouble codes and symptoms do not clarify the level of service needed, the customer can ship the module to us for internal component evaluation. This evaluation will determine what, if anything, is wrong with the module, as well as determining whether it can be fixed. This is a low cost, overnight service. From there AES can return the module to them with diagnostic notes, repair their original module, or remanufacture a replacement module for them. This reduces a repair shop's risk in servicing their customer and allows them to control the cost of the service.

From a product standpoint, when a remanufactured module is needed, AES works with recyclers around the country to obtain core modules to work with. These are then remanufactured. The recyclers are an integral player in this process because they know the history of the source vehicle, which avoids potential problems resulting from incorrect part numbers and security configuration. To leverage recycler domain knowledge and help recyclers become a quality supply chain player, AES developed Core Module Configuration and Quality Inspection criteria. As a result, both the recycler and AES operate with fewer mistakes. Recyclers benefit from the ability to sell control modules in a low risk venue.

When AES delivers a repaired or replacement part to the customer, service quality is in play again. Along with the part, the customer receives instructions as to what other parts might need to be replaced in order to protect the repaired or replacement module, and installation requirements to protect their investment in the part. This includes what on-board programming may be needed after installation. Getting out in front of potential problems is the best way to reduce or eliminate customer dissatisfaction issues.

ASE also hired ASE Certified Master Techs to help customers with the details of module replacement and diagnosis. The end result is that when a customer service issue arises, AES has the internal domain knowledge to deal with it. This is another aspect of the service surrounding the product.

Lastly, AES defined what they don't do. This allows AES to work within the limits of proven service abilities. It also helped to define what R&D was needed to expand the scope of their service.

The main intellectual take away for AES is this. Whether you are a recycler, repair facility, or a remanufacturer of automotive control modules, you operate in a process based industry. To become truly customer focused, your customer must be a part of the process. From a sales perspective, customers want to know that you care about their success as much as you do your own. This is true whether the customer is an end user, shop or warehouse distributor.

Wireless Network Site Survey Overview

Wireless Network Site Survey Overview

Overview

The site survey is an assessment of signal coverage per each access point (AP) within a specific building. It confirms with the client 100% coverage at a specified signal guaranteeing employees will have no issues with sending wireless packets across the network. Each building structure will have a design that determines signal characteristics. The most often issues that cause problems with decreasing wireless signals include water, metal, building contours and devices that emit electro-magnetic interference. Some access points can send a pattern of coverage extending 100 - 170 feet while some will emit a signal 50 feet with same characteristics. The building structural design has a lot to do with that.

The following is an overview of the site survey process:

1) Discuss Signal / Noise and Data Rate with Client

2) Obtain Floor Plans

3) Survey Buildings Noting Signal and Coverage

4) Document Access Point Placement

What then is an acceptable signal? Signal to noise separation of around 20 - 25 dBm at 54 Mbps is a minimum with most designs. The site survey software measuring a continuous 75 dBm signal and 95 dBm noise (75/95) would be enough to have employees connected and sending packets with same service level as wired clients. As signal weakens it becomes more difficult to distinguish between a signal of 80 dBm and noise of 95 dBm (80/95). There is less separation between signal and noise making the signal difficult to detect. It is counter intuitive that a larger number is a weaker signal however the key with signal and noise measurements is the signal is a negative number and hence a lower value is a bigger number. Discuss with the client what specific client adapter, 802.11a/b/g wireless standard and data rate they'll implement and survey with that. Deploying the 802.11a standard doesn't require a separate survey if you implement dual band and surveyed with 802.11g. Some companies with higher bandwidth demands will improve cell coverage with a separate 802.11a survey. It isn't as cost effective with additional access points deployed per cell coverage. Configure the access point with the selected 802.11a/b/g protocol, transmit power and data rate. Set the data rate and transmit power of the client adapter to maximum during the survey.

The site survey of a building involves walking around with a laptop on a powered cart configured with a Cisco wireless client adapter and the Cisco Aironet Desktop Utility (ADU). The software is a utility available with Cisco client adapters. The Cisco access point is placed at a specific spot on the ceiling or above the ceiling tile, wall, desktop or cubicle and measurements of signal coverage is noted. The access point is moved until optimal coverage occurs for that cell. Select ADU active mode to examine data rate, link status and errors while surveying. The cell coverage can be transferred to a Visio drawing floor plan with specific access placement and signal boundaries. The access point is moved around until the entire building is mapped. The minimum signal strength should be recorded per coverage cell. Be as specific as possible as you describe where access points should be implemented. Some clients will have floor plans which makes the site survey much easier to document coverage. Scan each floor plan as a Visio drawing noting specific placement of access points and assignment of channels.

Your map will have some overlapping of coverage which isn't a concern. You should assign a channel that doesn't overlap with neighbor cells and employees won't have any problem with channel interference. As mentioned the 802.11b and 802.11g wireless standards use the 2.4 GHz frequency band which can cause interference however there are 3 non-overlapping channels (1, 6 and 11) that can be assigned. As an example should your building have a main floor with 17 rooms and each access point cover 3 rooms use the following channel assignments:

AP1 Channel 1 Rooms 1-3

AP2 Channel 6 Rooms 4-6

AP3 Channel 11 Rooms 7-9

AP4 Channel 1 Rooms 10-12

AP5 Channel 6 Rooms 13-15

AP6 Channel 11 Rooms 16-17

In some instances you could have signal overrun between AP2 and AP5 with specific building design shapes. Decrease the transmit power from 100 mW to 20 mW on either or both access points and confirm signal strength is still acceptable at those rooms. Should the decreased transmit power setting not allow for same coverage, change position of the AP (access point), implement an additional AP at decreased wattage or an external antenna. Site surveys take some trial and error knowing where possible signal coverage will occur. You will know after doing some preliminary testing at a specific building what coverage to expect. Walk around with the laptop when starting and get some understanding of signal patterns. Signal overrun can often occur outside the building posing a security risk with hackers on the street. The site survey should confirm no signal overrun with minimized AP transmit power.

Multi-floor buildings will have some access points that will send signals across several floors. You can of course use fewer access points should APs cover those floors or decrease transmit power and assign non-overlapping channels as discussed. The issue with signal overrun is a concern where an AP covers some of a floor and not all of a room on another floor. You want APs spaced with proper signal coverage and minimal overlapping. Again the building could allow for an AP to cover a single floor or 2 floors with a signal strength as needed everywhere. Should a third floor exist you can deploy it on that floor. The first and second floor would have an access point on the first floor. Deploying on the second floor would cause signal overlap. That isn't an issue with non-overlapping channels, however clients with fast roaming should associate with the nearest access point. Having APs on second and third floors could cause some clients on the third floor to select a second floor AP over utilizing it and decreasing performance.

The client sends out a beacon and selects the nearest AP with the best signal, lower number of clients and matching security settings. A negotiation between AP and client adapter occurs and data is sent at the highest supported rate available. The coverage map with AP placement should be specific as possible during the survey describing access point placement. Deploy all APs and test connectivity. With all APs transmitting the chances for interference occurs and the design can be modified before deployment. Signal overrun outside can be tested confirming the signal stays within wall boundaries and there is no AP from the street. Spectrum analyzers can be deployed during the site survey or after to examine frequencies with interference and possible sources. Defining a security test plan is a good idea after deploying access points.

Make survey notes concerning mounting issues, where AC power outlets unavailable, distance between wiring closets and cabling distance between access point and switch. Cisco does have outside wireless bridges available connecting buildings with line of sight. There is a survey involved with deploying those bridges that considers path loss with transmitted signals and how environmental issues such as wind and rain will affect data transmitted.

Challenges for a HR Professional in BPO

Brand equity: People still consider BPO to be "low brow", thus making it difficult to attract the best talent.

Standard pre-job training: Again, due to the wide variety of the jobs, lack of general clarity on skill sets, etc, there is no standard curriculum, which could be designed and followed.

Benchmarks: There are hardly any benchmarks for compensation and benefits, performance or HR policies. Everyone is charting their own course.

Customer-companies tend to demand better results from outsourcing partners than what they could actually expect from their own departments. "When the job is being done 10,000 miles away, demands on parameters such as quality, turn around timeliness, information security, business continuity and disaster recovery, etc, are far higher than at home. So, how to be more efficient than the original?

Lack of focused training and certifications
Given this background, the recruiting and compensation challenges of HR departments are only understandable.

Key To success

The key to success in ramping up talent in a BPO environment is a rapid training module. The training component has to be seen as an important sub-process, requiring constant re-engineering.
Business Process Outsourcing: The Top Rankers
WNS has emerged as the top BPO in India, pushing Wipro Spectramind to the second position, according to a survey done by NASSCOM. The basis of ranking is the revenues generated by the BPO companies in 2003-04, as per US GAAP. A list of top fifteen BPO companies in India is given below.

Maternity Leave

Employee Stock Option Plan

Inspite of all these benefits, the attrition rate in BPO industry is very high, why?. What is the reason for an employee to leave? These and many more are the questions that need immediate attention from the industrial gurus.

Why people prefer to join BPO's?

In general a person with any graduation can join any of the BPO. Some BPO's like to take people with MBA but then again the specialization are of an individual hardly makes any difference. Again, this is the industry, where there is no reference checks and very often people don't even specify there exact age. Lets me share with you some of the reasons as why people prefer to join a BPO:

Did not get a better job.

Find nothing better to do.

Education level doesn't matter

Good work environment

Good Benefits

Flexibility of time

Attractive life style

Transport facility

Why people leave the BPO's?

When there are so many benefits associated with BPO industry....when there are so many privileges for the BPO employees than what makes them to change the company/industry?? Is it only MONEY that matters or anything else as well?? Here are some of the reasons for a BPO professional to change his/her job.

No growth opportunity/lack of promotion

For higher Salary

For Higher education

Misguidance by the company

Policies and procedures are not conducive

No personal life

Physical strains

Uneasy relationship with peers or managers

What they have to say?

With so much of uncertainty in the market.....people are trying their best to stop or to at least have a control on the attrition rate...let me share with you the opinion of the real gurus of the industry.

"Training is a very important aspect of the ITES-BPO industry"- Mr. Arjun Vaznaik, COO, Tracmail

" Career growth in the industry is robust and there is a long-term opportunity. The great growth momentum that the industry is witnessing is creating both vertical and lateral career opportunities. There also exists enough growth opportunities in the middle-management and supervisory level within the industry". - Aadesh Goyal, Executive Vice President & GM, Hughes BPO Services

"It will not be possible for the industry to arrive at a blanket agreement on poaching but bilateral agreements between companies are being signed. Basic norms are being put in place and code of ethics is being stressed upon by industry players within the sector with respect to HR practices. We are encouraging companies to adopt responsible behavior in order to ensure that the industry does not become a victim of its own actions. Industry needs to go aggressive but not cannibalistic." - Mr. Suren Singh Rasaily, Senior Vice President, NIIT Ltd. and Head Plantworkz,

Conclusion:

This is a descriptive report on BPO industry. I have tried to cover almost everything related to the industry. I like to have your opinion about the same. Even at the end of this comprehensive report, my concerns are related to development of employees in BPO, controlling attrition rate in BPO, can we have some standard industrial compensation package/ break-ups?

How to Check an Ignition Coil Or Fuel Injector - DIY Low Tech Method

How to Check an Ignition Coil Or Fuel Injector - DIY Low Tech Method

An ignition coil can be OHM checked with a meter to see if it is out of range or if it has a completely open circuit. But what if the car seems to run fine and a misfire code is directing you to a particular cylinder? For instance if you have a code for * P0301 (#1 misfire code) but the engine seems to be running OK, below is a low tech method for testing the coil without any special tools. This method works well for ignition coils or fuel injectors that may have an intermittent problem. Also it works best with ignition coils and injectors that are easily accessible. Obviously it's best to check the basics first like a visual inspection to see if engine oil may be shorting a connection or if there is evidence of tracking of the spark arcing to the engine. Sometimes after an engine is cleaned water can go into the spark plug recess and short the connection to the plug as well. The simple low tech method is assuming the spark plugs and wires are good and there is still a misfire code setting.

What is the low tech method?

Simple, switch the coil or injector with the neighboring one. After making the switch clear the code and see if the misfire code sets for the other cylinder. Sometimes in service manuals, you may read "install a known good component." This is basically what is being done without the expense of purchasing a new part for testing purposes. Usually with electronic parts, stores will not allow returns. This way no unneeded parts will be purchased.

Save money by using this simple low tech diagnosis method. Pinpoint intermittent problems with ignition coils or fuel injectors. Use this method without extensive knowledge of the ignition or FI systems. Perfect DIY test to verify a failing component without spending money or guessing. By switching cylinder #1 and #2 coils the code should move from * P0301 to P0302 if the coil is bad. Eliminate the possibility of bad wiring or a computer driver issue.

What Does the Check Engine Light Really Mean?

What Does the Check Engine Light Really Mean?

When a car's check engine light comes on, it is a mystery to most drivers. It instills panic in many for good reason. There are times when that light can mean drastic problems in a car's engine system or other operating parts. There are also times when it simply means you changed your brand of gasoline and the car needs to adjust to the new mix. For that reason there is a tendency to ignore that little light and hope the problem will go away.

Should You Worry About Your Check Engine Light?

How do you know if the check engine light is trying to tell you there is a serious problem or if it is nothing to worry about? One way is to take the time out of your busy schedule, drive to the mechanic and pay a hefty fee to have them hook up their machine to your car's OBDII system and then tell you to tighten your gas cap as a result. Or you can get your own OBD diagnostic tool that will give you all the information you need right at your fingertips.

Onboard Diagnostic System

These simple devices attach to your automobile's OBDII (onboard diagnostic system) right under the dash just like the big machine at the mechanic shop does and it will give you the exact same readouts plus provide easy to understand graphs and explanations of those confusing codes your mechanic gives you to keep you in the dark as to what is really going on.

Simply take the OBD diagnostic system for a short ride with you when your check engine light comes on and then take it in the house to your personal computer and download the data. The website provided to you with your OBD diagnostic system will decipher the information and give you all the information you need to determine if the problem is serious or not at fractions of the cost of a mechanic's garage. The readout will also give you simple solutions to the easier fixes if they are available plus if you do need to take the car to your mechanic, you can go in well-armed with the knowledge you need to keep from being overcharged for their services.

The OBD system will also alert you to potentially damaging driving habits you may have acquired over time even when your check engine light is not blinking. Things like hard braking and excessive acceleration so that you can correct problems before they affect your car's mechanisms.

Benefits of OBD

There are even more benefits to your own OBD diagnostic system. Never get stuck with a lemon again by taking it on all of your test drives. With your own diagnostic system, you will be able to find out for yourself if your potential new or used car is in good operating order before you drive off the lot. You can even find out why the check engine light [http://www.carcheckup.com/check-engine-light/] is on. You can also take all the worry out of vacations when you hook it up before a road trip.

Auto Repair Help Troubleshooting - Using General Diagnostics

Auto Repair Help Troubleshooting - Using General Diagnostics

Welcome to a briefly informative auto repair troubleshooting article. There is extreme consumption of time and money, if you are not ready for the auto repair shop. The vehicles of today are extremely complex, it takes training and skill to properly diagnose your vehicle. There are ways of educating yourself for the dreaded auto repair visit; therefore automotive diagnostic troubleshooting is essential information to obtain. Make sure the information you are receiving is credible. In this article I will examine general diagnostic troubleshooting and some procedures that follow.

Diagnostic trouble shooting for auto repair takes equipment, education and pure skill. Knowing a honest and reliable auto technician can be a great commodity. Having some general diagnostic knowledge will keep you from being ripped off and may help you to stay out of the repair shop. The Internet is rich with information and can help you in diagnosing your vehicle for repair, which will save you time and money. Remember this does not make you qualified for auto repair, but will help you to briefly understand what is involved.

Does the vehicle run? Many times I will diagnose a no start on a vehicle and it is something simple like a loose battery cable. Make sure you check all battery power & ground connections. Are the battery cable ends loose? Do they look corroded? A majority of the time you will find your no start condition is the battery connections or the battery itself.

Does the vehicle crank OK, but not start? When diagnosing a crank and no start, you will need some basic tools.

- Fuel Pressure gauge
- Compression tester
- Spark tester

These tools will help you to establish the most important duties a vehicle must perform in order to start. Fuel pressure, Compression and spark are the essential basics for an internal combustion engine to operate. Consult a qualified auto repair technician or the manufacturer for proper testing procedures.

The automobile starts, then dies? Many times on the newer vehicles, this condition will cause a check engine light, but is subject to the problem. No starts can have tail tale signs from the vehicles computer and may be intermittent. Usually a no start problem is due to an ignition component failure (crankshaft sensor, camshaft sensor, ignition module etc.). When diagnosing a vehicle that starts and then dies, make sure you harness the proper equipment for the job. Warning, Improper diagnosing techniques may result in damage to your cars computer. Use caution when attempting any form of vehicle auto repair troubleshooting.

Does the vehicle run, but has no power and a check engine light? Again remember the basics; fuel pressure, compression and spark the essentials to make your auto operate. These three parameters must first be examined to diagnose a drive ability or "check engine light" problem. Scan your vehicles computer for the check engine indicator light, which will get you to the circuit failure. The rest depends on what you have learned and or how much knowledge your auto repair consultant has.

In this article I have briefly examined some basic auto repair troubleshooting.

Slow Computer? 5 Most Common Causes or Reasons Why

Slow Computer? 5 Most Common Causes or Reasons Why

Computers are always in their tip-top conditions when we have just bought them. We appreciate how convenient and useful they are but after some time working with a computer, we suddenly notice ourselves getting impatient and irritable in front of them. It's not because you got some serious problem with yourself and you need to get some help psychologically. It's not you but it's your computer that's got a serious problem. It's gotten slower than before. You suddenly start to notice that your computer freezes from time to time, or it takes forever to open a file or make your computer do a task. That is because your computer has undergone some tremendous changes after a long time of using it or after a long time of getting access to the internet.

Below is a summary of the most common possible reasons why your computer is running slower and what you can do to fix it:

1. Too many programs running in the background. If you run your task manager and see a long list of processes, your computer may be using too much memory than it can handle. It can only do a definite amount of things at a time. Aside from the programs that you manually run, most of these processes are run automatically during startup. To fix this problem, you can disable some of the programs that automatically run during startup by running the msconfig application and unchecking some of the items in the startup tab if you're using Windows. You can also go to the services administrative tool and disable some of the services that automatically runs during startup. Restart your computer and you'll see that some of these programs are removed in the task manager's list of processes. However, if you can't live without all these programs, you can always get a new RAM and add more memory for your computer. This way, you can speed up your computer and run as many programs as you like.

2. Badly fragmented files. Fragmentation in computer is the scattering of files in your storage space causing the reduction of storage capacity and performance of your computer. This happens when the computer allocates a memory that is not properly used, leaving holes of storage space or causes the memory to be broken down or divided into small pieces. Fragmentation, when built up over time by running applications that do not properly deallocate memory, will cause the computer to lag down. This is because the computer has to do more rotations when searching a file in every separate space of memory. To fix this problem, you have to run a defragmentation tool to rearrange data storage so that related files are placed closely to each other. Patience is needed when defragmenting since it takes a long time to complete the process. The tool is available in windows but you can also get one from PC optimization and diagnostics softwares available online.

3. Cluttered Registry Errors. The registry is said to be the central nervous system of a PC's operating system. While the microprocessor is the brain of your PC's hardware, the registry is the brain of the operating system. It stores all information about system configurations, network settings and user profiles. Every time a computer performs a task such as accessing, installing, and uninstalling programs, or changing configurations and settings in your PC, an entry or a key is added to the registry. When these keys are no longer used, these are usually automatically deleted. However, some of these keys are either left behind or create holes causing fragmentation within the registry. These occur especially when uninstalling an application did not finished or when a computer did not shutdown properly. Useless and redundant keys pile up to form a cluttered registry making it hard to access valid keys and causing errors because the keys do not point to an existing file or document. Registry errors are sometimes the cause why a computer crashes, freezes or boots so slowly. The best way to fix registry errors is to get a trusted reputable registry cleaner online. Although there is a way to manually fix registry errors, registry cleaners can automatically scan and fix your registry, saving you a lot of time.

4. Computer is full of Temporary Files. Every time you run an application, temporary files are sometimes created. Temporary files are used to back up or store temporary data while the program is running especially for those that handle large files like image editing, word processing, and video editing programs. When an application ends or closes, temporary files are usually deleted; however, an application could sometimes meet an unexpected error and fails to delete these temporary files while it terminates. On the other hand, some applications just don't delete them because they might be of use in the future. When temporary files accumulate from time to time, they cause major fragmentation of storage space which in turn affects the computer's performance. This is evident when you run an application continuously for days and suddenly when you check back, your computer is already very slow, then, you can find a bunch of temporary files stored in your hard drive. Running applications is not the only source of temporary files; using the internet also creates these temporary files as well. That is why it is necessary to get rid of these files. A common solution to these is to run the disk cleanup tool in Windows but some registry cleaners and pc optimization tools provide a similar service too as well. After which, you can defragment your PC to speed it up once again.

5. Your computer has been infected or intruded. A Virus is probably the most notorious thing in the internet. Just like Satan, it is the old dragon of the web. It is there for who knows when. When your computer gets infected, it means the virus has already multiplied and you will suddenly notice a tremendous loss of free storage space. A Spyware, on the other hand, is like a bad secret agent of the internet. It stealthily maneuvers deep in your PC to wait for an opportunity to spy and collect valuable information about you.
