Handles, Locks, Latches and Entry Systems - Project 8: 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 Body Control Module/Gateway Module (BCM/GWM). In North American Specification (NAS) markets, the luggage compartment lid latch can also be released mechanically, by an emergency release handle and cable. The BCM/GWM controls the Central Door Locking (CDL) system, including the electrical locking and unlocking of the doors and the fuel flap.

The CDL system is part of the vehicle security system and includes the following components:

• The controlling software within the BCM/GWM
• The smart key(s)
• The Radio Frequency (RF) receiver
• The Remote Function Actuator (RFA)
• The Driver Door Module (DDM)
• The Passenger Door Module (PDM)
• The Rear Door Module (RDM) in each rear door
• The door latches
• The luggage compartment lid latch
• The hood switch
• The fuel flap release motor
• The interior lock/unlock switches
• The interior and exterior door handles.

The BCM/GWM monitors the lock and unlock requests, from the following:

• The smart key via the RF receiver and the RFA.
• The interior lock and unlock switches.

A passive entry system is installed, which incorporates a lock switch and an unlock switch in each exterior door handle, and 3 Low Frequency (LF) antennas. The passive entry system operates the CDL system without having to press the switches on the smart key. 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 RFA, which transmits the lock and unlock requests to the BCM/GWM for action by the CDL system.
