1

Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

Verify that the Door Ajar Indicator Malfunction complaint is present.

Does the Door Ajar Indicator System operate as described in the System Description and Operation?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Close all doors.
4. With the scan tool, observe the parameter of each Door Ajar Switch in each door control module data list.

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

Go to Step 4

Go to Step 5

1. Open all of the vehicle doors.
2. With the scan tool, observe the parameter of each Door Ajar Switch in each door control module data list.

Does the scan tool indicate that the Door Ajar Switch is in the Door Ajar state for all doors?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 6

1. Turn OFF the ignition.
2. Disconnect the suspect door latch assembly.
3. Turn ON the ignition, with the engine OFF.
4. With the scan tool, observe the appropriate Door Ajar Switch parameter.
