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.

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.

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.
