Motronic fault using Durametric Code Reader


Recommended Posts

On a 1997 993 cabrolet, I'm trying to help a friend check out why the check engine light stays on. I'm using the Durametric code reader and getting a Motronics Fault. When I clear the fault and Durametric checks for faults, the fault show up again. Durametrics will also not pull up the VIN and other information. It does check the ABS and Air conditioning so I know it is working. It also works for all codes on my 99 carrera so I don't think there is a software problem. The only known problem besides the check engine light being on is that the top does not go up and down automatically. I don't think the problems are related.

Any suggestions on where to start?

Some of the older 993's do not have much information to look at. Very early days of OBD.

What are the fault code(s)?


Thanks for the reply. I talked to Durametrics and they recommnended I download the latest version of their software and it allowed me to read the VIN , etc and reset the fault. It was a motronic fault. I guess a general fault which I cleared and hasn't come back yet.

Great website and great software.
