A scan tool with enhanced diagnostics can save your a lot of time and worry and allow you to do most of the troubleshooting from the drivers seat.

If you have a 1996 or newer vehicle, you have OBD II. But just because it's generic and the connector will plug into your car doesn't mean any scan tool will work on your car. If you have a 1998 or later European vehicle the scan tool will need a software upgrade. Another potential problem vehicles are Korean and the scan tool may need software upgrades to read them correctly.

There are several brands of scan tools, each with different capabilities and options. If you decide to purchase one for your use, shop around and get the one that will serve your needs.

As anyone with a household PC knows, "plug and play" doesn't always work, and OBD II scan tools can encounter compatibility problems. Some European and Korean cars don't always work when they're supposed to. How can you tell? Checking a scan tool manufacturer's Web site for updates is the way to keep your tool current.

  It's many years since OBD II has come out and the early vehicles are now out of warranty. OBD II is a very complex system and I can only scratch the surface here, but hopefully it is a little less of a mystery now. Modern OBD II computers are a lot better than the early ones and are getting better every year. They can detect more problems and are much better storing the DTC's it finds.

The OTC/SPX Genysis carries the highest level of diagnostic information available to date. SPX creates the software that is used to operate the vehicles and has the most up to date software available. Although the most expensive of the bunch, you do get what you pay for. The Nemysis is the little brother to the Genysis and is less expensive but as suspected does not offer as many features.

The OTC Nemysis is the latest scan tool developed by OTC/SPX Corporation. Nemysis is an automotive scan tool designed and powered by Genysis technology. Nemysis covers early OBD I systems and all OBD II protocols, including the newly released Controller Area Network (CAN) protocol. Can protocol was introduced in 2003 model year vehicles and is the mandated protocol in all new vehicles by 2008. Matco Tools calls the nemysiss PRO SCAN PLUS. See the all New Pegysis From OTC.
