Handles, Locks, Latches And Entry Systems (G1818068): Overview

The hinged panels are secured with latches and strikers. The hood and door latches are released by lever/handle and cable mechanisms. Release of the luggage compartment lid latch is electrical, controlled by the CDL (Central Door Locking) system. In NAS (North American Specification) markets, the luggage compartment lid latch can also be released mechanically, by an emergency release handle and cable. The CDL system also controls the electrical locking and unlocking of the doors and fuel flap.

The CDL system includes the Smart key(s), the RF (Radio Frequency) receiver and the controlling software in the BCM/GWM (Body Control Module/Gateway Module). The BCM/GWM monitors the lock and unlock requests, from the Smart key(s) via the RF receiver and KVM (Keyless Vehicle Module), and from the lock and unlock switches, then provides the appropriate outputs to the door modules and/or the locking motors in the latches.

A passive entry system may be installed, depending on model and market specification. Vehicles fitted with the passive entry system incorporate a lock switch and an unlock switch in each exterior door handle, and four LF (Low Frequency) antennas. The passive entry system operates the CDL system without having to press the switches on the Smart key(s). Provided a valid Smart key is present, the doors can be unlocked and locked using the exterior door handles, and the luggage compartment lid can be opened using the exterior unlock switch. The passive entry system is controlled by the KVM, which transmits the lock and unlock requests to the BCM/GWM for action by the CDL system. For additional information, Refer to: ANTI-THEFT - PASSIVE
