Circuit/System Testing

  1. Ignition OFF, disconnect harness connector at the driver door latch assembly.
  2. Test for less than 10 ohms between the ground circuit terminal 8 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the door ajar indicator is not illuminated.
    • If the indicator is illuminated, test the signal circuit terminal 6 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 6 and the ground circuit terminal 8. Verify that the door ajar indicator is illuminated.
    • If the indicator is not illuminated, 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 circuit tests normal, test or replace the driver door latch assembly.
