2. With the ignition ON, lower the driver door window. Ignition OFF, remove key and close and lock all doors and liftgate/liftglass. Reach in and open the driver door with the driver door handle. Alarm should sound and exterior lights should flash.

Circuit/System Testing

1. Ignition ON, with the scan tool, check for any current DTC. Diagnose any current DTC.
2. With the scan tool verify all entry points are closed. Perform system verification. Verify that the content theft system is inoperative.

• If the theft system is inoperative, replace the BCM. Refer to repair instructions.
