Principles of Operation (Vehicles with Remote Keyless Entry (RKE)

RKE locking system overview

This system consists of mechanical/electrical operated door latches driven by inputs from electronic door control modules. The system uses a radio frequency (RF) transmitter and receiver to operate the remote lock/unlock functions and normal key or remote door handle inputs for standard central and double locking functions.

When the remote handle is operated, switching contacts within the door latch supply a command signal to the door control module. The door control module communicates with the GEM using the central area network (CAN) bus circuit. Dependant upon the current state of the locking system, commands are then sent to all of the door control modules, which in turn allow battery voltage to be applied to the door latch motors.

The fuel filler door lock function is controlled by the GEM. The GEM receives the lock command from the door control module. The GEM operates the lock relay which supplies a voltage to the fuel filler door lock motor. To unlock the fuel filler door, the supplied voltage is reversed using the driver door/fuel filler door unlock relay.

The liftgate or luggage compartment lid is opened when the vehicle is in the unlocked mode by a ground signal from the liftgate/mimi-liftgate compartment lid release switch to the GEM. The GEM will supply a voltage to the liftgate or mimi-liftgate compartment lid latch motor.

If the vehicle is locked, the input from the liftgate/mini-liftgate compartment lid release switch will be ignored.

The RKE functions are operated by sending a radio frequency (RF) signal from the key transmitter. The signal is received by the vehicle remote RF receiver. For vehicles fitted with the Keyless system the RF signal is transferred to the keyless vehicle module and a signal is transmitted to the corresponding lock sent via CAN to the GEM module.

Keyless Vehicle System Overview

NOTE: Vehicles fitted with Keyless system the remote codes are programmed to the keyless vehicle module

The keyless vehicle system also incorporates RKE functions, however the main purpose of the system is to allow the operator of the vehicle to gain access to and operate the vehicle without carrying out any actions with a key or remote buttons.

The keyless vehicle system can be turned off to give basic key operation if required.

To isolate the keyless vehicle system, the emergency key must be inserted into the ignition switch turning knob and the ignition switch turning knob rotated to position II. It is now possible to select the KEY FREE ON or KEY FREE OFF from the instrument cluster liquid crystal display (LCD) using the remote steering column stalk control. In the OFF mode, the RKE functions still work.

Vehicles equipped with keyless vehicle systems, will be delivered from production in shipping mode.

Shipping mode reduces the vehicle battery drain to a minimum to extend the period of time the vehicle can remain dormant without discharging the vehicle battery.

To exit the shipping mode, the emergency key must be inserted into the ignition switch turning knob and rotated to position II. The shipping mode can now be deselected from the instrument cluster LCD display using the steering column stalk control.
