Do you know where I can find the procedure to access the BCM and then reseat the connectors? I really don't want to go back to my dealership for this. I already paid them $250 in labor before just for them to tell me the BCM is bad.Nothing special about unplugging and reseating the connectors. Just disconnect the negative cable on the battery first. The other items programmed into the BCM are the ident codes for your FOBs so it will recognize them and the PCM is programmed to recognize the identity of the BCM. It's all part of the immobilizer scheme.
