Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the appropriate door latch assembly.
  2. Test for less than 1.0 ohm between ground circuit terminal listed below and ground:
    • Driver door latch assembly ground circuit terminal 8
    • LR door latch assembly ground circuit terminal 6
    • Passenger and RR door latch assembly ground circuit terminal 3
      • If not the specified value, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify the scan tool Door Ajar Switch is Door Closed.
    • If not the specified value, test the signal circuit terminal listed below 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 and the ground circuit terminal listed below. Verify the scan tool Door Ajar Switch is Ajar.
    • Driver door latch assembly signal circuit terminal 6 and ground circuit terminal 8
    • LR door latch assembly signal circuit terminal 4 and ground circuit terminal 6
    • Passenger and RR door latch assembly signal circuit terminal 1 and ground circuit terminal 3
      • 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 door latch assembly.
