Rear Door Ajar Switch Malfunction

  1. Ignition OFF, disconnect the harness connector at the appropriate rear door latch assembly.
  2. Test for less than 1.0 ohm between ground circuit terminal listed below and ground:
    • LR door latch assembly ground circuit terminal 6
    • 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 Rear Door Ajar Switch parameter is Door Closed.
    • If not the specified value, test the signal circuit terminal listed below for a short to ground:
    • LR door latch assembly signal circuit terminal 4
    • RR door latch assembly signal circuit terminal 1
      • 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:
    • LR door latch assembly signal circuit terminal 4 and ground circuit terminal 6
    • RR door latch assembly signal circuit terminal 1 and ground circuit terminal 3
  5. Verify the scan tool Rear Door Ajar Switch parameter is Door Ajar.
    • 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.
  6. If all circuits test normal, test or replace the appropriate rear door latch assembly.
