      No 

      • If a camera was swapped from a like configured vehicle return the camera to that vehicle.
      • If the camera has been replaced because a like configured vehicle was not available, perform the BODY VERIFICATION TEST. Refer to BODY VERIFICATION TEST .
  3. TEST THE REAR CAMERA CIRCUITS
