WARNING: This page is about a different car, the 2002 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The theft deterrent ECU receives information about vehicle door status from the body control ECU across the multiplex communication bus. The body control ECU monitors the status of the door courtesy switches to determine if a door is open or closed. For testing procedures, see BODY CONTROL SYSTEMS - AVALON
