Hey all! New Corvette owner here! 2006 coupe 6 speed manual.
I bought the car with the ABS and TC lights and the service and/tc/ah messages displaying on the dic.
I removed the electric side of the EBCM, checked for voltage and ground on the harness at the applicable pins. Both were okay. I thought I found the problem (bad connection on black plastic bridge connector) and re assembled it but nope! Lights all still on.
I had it scanned and have the following codes.
C0121
C0899
C0110
C0252
Can I accurately diagnose this without a Tech 2? Any help is greatly appreciated. I am willing to replace the EBCM but I want to have a concrete diagnosis before throwing parts at the car.
Do I need to replace my EBCM?
