  One Response to “03 IMPALA ,HOW TO TEST BCM FUNCTION”

  1. Testing the BCM (Body Control Module)requires a High End Scan tool. Most dealerships have these in there shops with the ability to run vehicle specific tests including testing the BCM.
    The BCM controlls just about everything in a car that the ECM(engine control module) doesn’t.
