Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hi,my name is ***** ***** I will be happy to try to assist you with this.I may need more information in some cases to help with answering your question.
When the BCM is replaced it has to be replaced with a new unprogrammed BCM.If you were to install a BCM that is already programmed to a different vehicle it cannot be reprogrammed to your vehicle and the vehicle will not start.A GM dealer has to program the BCM after it is replaced.
You can sometimes obtain a new replacement pre programmed BCM through a local parts store.If you have not contacted one of these facilities I would see if they can obtain one of these for you.
