Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

1. Observe the following parameters in each of the door modules data list:

•	Driver Door Jamb Sw.

•	Pass. Door Jamb Sw.

•	Left Rear Door Jamb Sw.

•	Right Rear Door Jamb Sw.

2. Open and close each door while observing the respective parameter.

Does the scan tool display change from On to Off?

Go to Symptoms - Lighting Systems in Lighting Systems

1. Install a scan tool. Select diagnostic circuit check and then class 2 power mode.
2. Close all the doors.
3. Turn ON the ignition, with the engine OFF.
4. Wait 5 seconds then turn the ignition OFF.
5. Wait the time-out for retained accessory power (RAP).

Did the scan tool display the RAP power mode, then time-out and display Off-Awake power mode?
