Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

1. Observe the following parameters in BCM data list:

•	Driver Door Jamb Sw.

•	Pass. Door Jamb Sw.

•	Side Door Jamb Switch

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

Does the scan tool display change from Active/On to Inactive/Off?

Go to Step 3

Go to Symptoms - Lighting Systems in Lighting Systems

1. Observe the RAP Relay parameter under BCM outputs.
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 On, then time-out and display Off?
