I have been trying to understand the effects of a failing BCM, when I put the car in drive 98% of the time I get Traction Control Off warning immediately, Cruise control will not work and overdrive will not lock up, also transmission will not downshift into first either when I first start the car or when I come to a stop while driving. Check Engine light is always on and I have had intermittent air bag and charging system failure warnings. Remote start has stopped working. 2% of the time Traction Control warning does not come up and overdrive and cruise work usually until I encounter a hill and the Tranny has to downshift,then I get the TC light and loose overdrive. My codes read at the auto parts store show shift solenoid failure but I think that there is more going on than that. Has anyone had similar multi system issues?
