Service Engine Soon....ARGHHH!
Lately my 2000 mn6 Coupe has been giving me the 'Service ABS, TC, and AH' message upon start up. Shuting off and restarting has cleared it all but once. After searching the forum here I checked my grounds and checked the harness at the ECBM by disconecting it. After reconecting everything, I now have a 'Service Engine Soon' in the DIC. Pulling codes reveals:
PCM-P1571 / TCS-No Comm. / BCM-B0502, B0507, B2482
Anybody have a clue as to what may have gone wong?
I would greatly appreciate any help, and provide a beverage of choice to anyone who helps that is near or will be near South Florida!
Thanks,
Ray

I'd manually delete all of the codes stored, especially if they are H (History) codes. See :
https://www.corvetteforum.com/techti...D=26&TopicID=1
For a description of how to delete the codes.
Then drive the car and check to see if any codes re-post. You may simply be seeing left over codes from before cleaning grounds, etc.

The codes you're getting are...
B0502 - RH DRL Relay Circuit
B0507 - LH DRL Relay Circuit
B2482 - Backup Lamp Relay Circuit
None appear directly related to the ABS, Traction Control or Active Handling...
These are related to the BCM... in the passenger side footwell. I would first check the area for any water or moisture. If you find any moisture, go through Bill Curlee's sticky at the top and it will give you lots of info on dealing with this. In fact I would recommend reading it anyway, you will learn more about the foibles of the C5 electrical system than you thought possible...
Good luck... GUSTO
