Circuit/System Testing

  1. Ignition OFF, disconnect the trunk release relay.
  2. Connect a test lamp between the relay coil B+ circuit and the relay coil control circuit.
  3. Command the trunk release ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
    • If the test lamp is always ON, test the control circuit for a short to ground. If the circuit tests normal, replace the BCM.
    • If the test lamp is always OFF, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
  4. If all circuits test normal, test or replace the trunk release relay.
