Folks,
My 2005 V8 is acting up...
Renewed my ABS ECU recently, but I now get HDC Fault, Suspension inactive messages, DCS light is on but NOT the ABS and brake warning lights. This only happens after I drive for a while. Next morning all is well until I drive for 20-30 minutes and it is all back again.
Associated issue: I can only read (using GAP scanner) the ABS ECU when stationary. When I take off communication with the ABS ECU is gone, until I come to a standstill. At this point communicating with the ABS ECU brings all warning lights on - they extinguish when I start driving again.
What gives?
