Darn ABS / TC lights on dash
This popped up this week after I got my car out of the shop for some body work. 2001 C5
DIC says service ABS/ Traction Control. and they both light up on the dash.
Checked fuses: 5,7,52,53, and relay 41 and all are good
Codes are:
B2284H
U1000H
U1064H
C1214HC
C0615HC
C0690 H
C0691H
B3067H
B2284H
C1214HC
I had the EBCM rebuilt 5 years ago and the supplier says the codes do not reflect a problem with it.
Any ideas what my problem is.... thanks so much, Ron

Assuming your battery is okay and the wiring harness to the EBCM is okay, then your EBCM has failed. Most likely either the power relay failed or has broken solder connections to the PCB. Perhaps the last repair shop's work was not as good as it should have been.

Highlighted code bove is the main power relay in the EBCM. ABSOLUTELY will illuminate the ABS/AH/TC lights on the dash and disable ABS. TC and AH for the current ignition cycle.
C0690, C0691 and C0615 are all issues with the electronic suspension control. Your profile says you have C6Z06 shocks. Most likely you did not program out the F45 RPO or if you used resistors or sims they have failed.
