Substitution of control modules does not guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests

1. Verify the customer concern, to be sure the correct issue is investigated

2. Visually inspect for obvious signs of mechanical or electrical damage

Handles, Locks, Latches and Entry Systems - Overview

OVERVIEW

All the vehicle hinged panels are secured by latches with mating strikers. The latches incorporate panel ajar switches that will inform the driver of an open access point.

The central locking system is operated by either the remote handset or the front door central locking buttons. The central locking system controls the automatic locking and unlocking of the vehicle entry points. The software used to control the central locking system is incorporated within the CJB (central junction box).

The central locking system is also integrated with the interior lighting function. The interior lights and exterior mirror lamps are illuminated via the RF receiver and CJB following a valid unlock request from the remote handset. For additional information, refer to: (417-02 Interior Lighting)

If configured by the dealer, the exterior door mirror power fold function is also operated by the central locking system.

A concealed mechanical door lock is provided in the front LH (left-hand) door exterior handle, and is used to gain access to the vehicle if the battery is discharged or the central locking system fails.
