Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the rear compartment lid ajar switch.
  2. Ignition OFF, test for less than 1 ohm resistance between the ground circuit terminal B and ground.
    • If greater than 1 ohm, test the ground circuit for an open/high resistance.
  3. Using a scan tool, verify the Trunk Ajar Switch parameter displays Trunk Closed.
    • If not Trunk Closed, test the rear compartment lid ajar switch signal circuit for a short to ground. If the circuit tests normal, replace the BCM.
  4. Install a 3-amp fused jumper between the rear compartment lid ajar switch signal circuit terminal A and ground. With a scan tool, verify the Trunk Ajar Switch parameter displays Trunk Ajar.
    • If not Trunk Ajar, test the rear compartment lid ajar switch signal circuit for a short to voltage or an open/high resistance. If circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the rear compartment lid ajar switch.
