WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the rearview camera.
  2. Engine running, park brake applied, transmission in REVERSE, test for B+ between the B+ circuit terminal 3 and ground.
    • If less than the specified value, test the control circuit for a short to ground or an open/high resistance.
  3. If all circuits test normal, replace the BCM.
