Trunk Release Inoperative from Key Switch

  1. Ignition OFF, disconnect the harness connector at the rear compartment lid pull down actuator.
  2. Test for less than 1 ohm of resistance between the ground circuit terminal F and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool trunk key cylinder switch parameter in Theft Data is INACTIVE.
    • If not the specified value, test the signal circuit terminal E for a short to ground. If the circuit tests normal, replace the BCM.
  4. Install a 3A fused jumper wire between the signal circuit terminal E and ground. Verify the scan tool trunk key cylinder switch parameter is ACTIVE.
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
  5. If all circuits test normal, test or replace the rear compartment lid pull down actuator.
