2002 GT
ABS light has been on. Would go off then come back on once in a while. It's been on now for about 9 months. Finally read the codes and got:
C1805 Mismatched PCM and/or ABS/Traction control module
All the parts are the original OEM stuff.
I've cleaned out the connector on the ABS module.
Checked all ABS rings and speed sensors.
Just generally gone over stuff to see if anything looked bad.
I have a Diablo tune in it with the traction control turned off. I have noticed that sometimes the "TC Off" light will be on like it should when the car is running, other times it's off. Whether it's on or off the TC is still disengaged.
I don't have the online diagnostic resources I used to have so I figured I'd post up and see if anyone has any ideas or has had this problem before.
