Front Door Ajar Switch Malfunction
- Ignition OFF, disconnect the harness connector at the appropriate front door latch assembly.
- Test for less than 5.0 ohms between ground circuit terminal listed below and ground:
- Driver door latch assembly ground circuit terminal 8.
- Passenger door latch assembly ground circuit terminal 3.
- If greater than the specified range, test the ground circuit for an open/high resistance. If the circuit tests normal, replace the appropriate door module.
- Ignition ON, verify the scan tool Door Ajar Sw parameter is Inactive.
- If not the specified value, test the signal circuit terminal listed below for a short to ground:
- Driver door latch assembly signal circuit terminal 6
- Passenger door latch assembly signal circuit terminal 1.
- If the circuit tests normal, replace the appropriate door module.
- Install a 3A fused jumper wire between the signal circuit terminal and the ground circuit terminal listed below:
- Driver door latch assembly signal circuit terminal 6 and ground circuit terminal 8
- Passenger door latch assembly signal circuit terminal 1 and ground circuit terminal 3
- 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 appropriate door module.
- If all circuits test normal, test or replace the appropriate front door latch assembly.
