IceCold Posted April 12, 2015 Report Share Posted April 12, 2015 Good day all: I tried to activate my onstar yesterday but all i get is the systems prerecorded message that's built into the car. When I press the on-star button again 2nd time, it tells me to please wait connecting to onstar with several beeps and it never connect. I called onstar and they ran my vehicle information and indicated that I should be fine with the new digital service already installed and suggested that I take the vehicle to the dealer for a system check, which i'm not doing. I'm receiving the following codes abs c1298 History amp u1000 Current ipm B0429 Current no irc data pcm u1040 History My traction control light stays on unless I clear codes and not restart the car. I have a new ECM (computer) that needs programming and install which I plan on doing soon, which may eliminate everything but ipm B0429 (rear AC Actuator). "IRC data" is my radio, I have an aftermarket with all the correct adapters to retain onstar, steering wheel control etc. Any suggestions or advice?
