ABS/Traction Lights Help Diagnosing Codes
I have a 1998 C5M6 72k miles.
When using the car’s onboard diagnostics, it shows 3 codes. I’ve reset them all and they come right back on immediately.
PCM codes (P1571 H C & P1644 H C).
TCM shows no communication
I also have a B2860 H C which seems to have no bearing on this.
From what I can gather, the PCM codes seem to be saying they aren’t talking to the EBTCM, which makes sense since the TCM shows no communication. Any thoughts on where to go on this? Bad EBTCM module?
