Door Ajar Indicator Malfunction

For vehicles with the driver express up and express down features, the driver window motor will supply a 12 V signal to the driver door ajar switch signal circuit. For vehicles with all windows with express down features, the body control module (BCM) supplies a 12 V signal to each door ajar switch signal circuits. The door ajar switches are integral to each door latch assembly. When a door is opened, the normally open door ajar switch closes. With the door ajar switch closed, ground is provided to the door ajar switch signal circuit. The window motor and/or BCM will detect the voltage drop and will communicate the door ajar via serial data with the instrument panel cluster which will display the appropriate door ajar message.

Electrical Information Reference

Scan Tool Reference

Control Module References for scan tool information

1. Ignition ON, observe the scan tool Driver Door Ajar Switch parameter while opening and closing the driver door. The parameter should change between Active and Inactive.

⇒	If the value does not change, refer to Driver Door Ajar Switch Malfunction.

2. Observe the scan tool Passenger Door Ajar Switch parameter while opening and closing the front passenger door. The parameter should change between Active and Inactive.

⇒	If the value does not change, refer to Passenger Door Ajar Switch Malfunction.

3. Observe the scan tool Left Rear Door Ajar Switch and Right Rear Door Ajar Switch parameters while opening and closing the left and right rear doors. The value should change between Inactive and Active.

⇒	If a value does not change, refer to Rear Door Ajar Switch Malfunction.

Driver Door Ajar Switch Malfunction

1. Ignition OFF, disconnect the harness connector at the A23D door latch assembly - driver.
2. Test for less than 10 Ω 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 scan tool Driver Door Ajar Switch parameter is Inactive.

⇒	If not the specified value, test the signal circuit terminal 6 for a short to ground. If the circuit tests normal, replace the M74D window motor - driver (AXG) or S79D window switch-driver (AEC).

4. Install a 3 A fused jumper wire between the signal circuit terminal 6 and ground. Verify the scan tool Driver Door Ajar 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 M74D window motor - driver (AXG) or S79D window switch-driver (AEC).

5. If all circuits test normal, test or replace the A23D door latch assembly - driver.

Passenger Door Ajar Switch Malfunction

1. Ignition OFF, disconnect the harness connector at the A23P door latch assembly - passenger.
2. Test for less than 10 Ω between the ground circuit terminal 3 and ground.

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the scan tool Passenger Door Ajar Switch parameter is Inactive.

⇒	If not the specified value, test the signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the S79P window switch - passenger.

4. Install a 3 A fused jumper wire between the signal circuit terminal 1 and ground. Verify the scan tool Passenger Door Ajar 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 S79P window switch - passenger.

5. If all circuits test normal, test or replace the A23P door latch assembly - passenger.

Rear Door Ajar Switch Malfunction

1. Ignition OFF, disconnect the harness connector at the appropriate rear A23 door latch.
2. Test for less than 10 Ω between the ground circuit terminal listed below and ground:

•	Left rear door latch ground circuit terminal 8

•	Right rear door latch ground circuit terminal 3

⇒	If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, verify the appropriate scan tool Rear Door Ajar Switch parameter is Inactive.

⇒	If not the specified value, test the signal circuit terminal listed below for a short to ground. If the circuit tests normal, replace the K9 BCM.

•	Left rear door ajar switch signal circuit terminal 6

•	Right rear door ajar switch signal circuit terminal 1

4. Install a 3 A fused jumper wire between the signal circuit terminal listed below and ground. Verify the scan tool Rear Door Ajar Switch parameter is Active.

•	Left rear door ajar switch signal circuit terminal 6

•	Right rear door ajar switch signal circuit terminal 1

⇒	If not the specified value, test the signal circuit terminal listed below for an open/high resistance. If the circuit tests normal, replace the K9 BCM.

5. If all circuits tests normal, test or replace the rear A23 door latch.

Static Test

1. Ignition OFF, disconnect the wiring harness plug at the appropriate A23 door latch assembly.
2. With the switch in the open position, test for infinite resistance between the signal terminal and the ground terminal listed below:

•	A23D door latch assembly--driver terminal 6 and terminal 8

•	A23LR door latch assembly--left rear terminal 6 and terminal 8

•	A23RR door latch assembly--right rear terminal 1 and terminal 3

•	A23P door latch assembly--passenger terminal 1 and terminal 3

⇒	If not the specified value, replace the door latch.

3. With the switch in the closed position, test for less than 5 Ω between the signal terminal and the ground terminal listed below:

•	A23D door latch assembly--driver terminal 6 and terminal 8

•	A23LR door latch assembly--left rear terminal 6 and terminal 8

•	A23RR door latch assembly--right rear terminal 1 and terminal 3

•	A23P door latch assembly--passenger terminal 1 and terminal 3

⇒	If greater than the specified range, replace the door latch.
