cannot connect to DME


Recommended Posts

MY03 996 GT3 Cup Car, Check engine light is on, Cannot connect to DME with multiple scanners including Porsche factory scanner. The Bosch ECU MS3.2 B 261 208 260.

Can anyone confirm that this is the correct Cup Car DME?

Does anyone have MY03 996 Cup Car wiring diagram so I can confirm continuity from the DME to the OBDII connector?

Any other suggestions for troubleshooting this problem?

The 2003 GT3 Cup I worked on had MS3.1. I used the factory Modas system to connect to the DME. It doesn't connect to the OBD2 socket, but to the diagnostic connector on the roll cage, near the back of the right hand door. It uses the ETAS interface. Durametric do a version for the Cup car, but it isn't quite as comprehensive as MODAS.

I have the (very rare) wiring diagrams, which I converted from DXF to PDF format. Drop me a PM with your email address if you would like them.
