Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle

Verify that the Door Ajar message or indicator malfunction is present.

Does the Door Ajar message/indicator operate as described in the system description and operation?

Go to Testing for Intermittent Conditions and Poor Connections

Go to Step 3

1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Close all doors.
4. With a scan tool, navigate to the body control module (BCM) Inputs Data List and observe the parameter of each door ajar switch:

•	LF Door Ajar Switch

•	RF Door Ajar Switch

•	Left rear Door Ajar Sw.

•	Right rear Door Ajar Sw.

Does the scan tool indicate that the Door Ajar Switch parameter is Closed for all doors?

Go to Step 4

Go to Step 5

1. Open all of the vehicle doors.
2. With the scan tool, observe each door ajar switch parameter in the BCM Inputs Data List:

Does the scan tool indicate that the door ajar switch parameter is Ajar for all doors?

Go to Testing for Intermittent Conditions and Poor Connections

Go to Step 6

1. Turn OFF the ignition.
2. Disconnect the harness connector at the malfunctioning door lock.
3. Turn ON the ignition, with the engine OFF.
4. With the scan tool, observe the inoperative door ajar switch parameter.

Does the scan tool display Closed?

Go to Step 11

Go to Step 9

1. Turn OFF the ignition.
2. Disconnect the harness connector at the malfunctioning door lock.
3. Connect a 3-amp fused jumper wire between the door ajar switch signal circuit and ground.
4. Turn ON the ignition, with the engine OFF.
5. With the scan tool, observe the appropriate door ajar Switch parameter.

Does the scan tool display Closed?

Go to Step 7

Go to Step 8

1. Turn OFF the ignition.
2. Connect the 3-amp fused jumper wire between the door ajar switch signal circuit and the ground circuit.
3. Turn ON the ignition, with the engine OFF.
4. With the scan tool, observe the appropriate door ajar switch parameter.

Does the scan tool display Ajar?
