Circuit/System Testing

WARNING: This page is about a different car, the 2010 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at each of the object alarm sensors.
  2. Ignition ON, verify DTC B1E3A is not set as current.
    • If DTC is set, test the 8 V reference circuit terminal 1 for a short to voltage, short to ground, or an open/high resistance. If circuit tests normal, replace the rear object sensor control module.
  3. Install each sensor harness connector one at a time, checking DTCs after each sensor is connected. Verify DTC B1E3A is not set as current.
    • If DTC is set, replace the object alarm sensor that was connected immediately before the DTC set.
