Handles, Locks, Latches and Entry Systems - System Operation and Component Description

The luggage compartment lid latch can be released using:

the interior luggage compartment lid release switch. the exterior luggage compartment lid release switch. a valid programmed passive key.

The BCM sends voltage signals to the interior and exterior luggage compartment lid release switches. When a luggage compartment lid release switch is pressed, the voltage signal is routed to ground, indicating a request to release the luggage compartment lid latch. The BCM momentarily provides voltage to the luggage compartment lid latch to actuate the release motor.

When using the luggage compartment lid release switches, the BCM releases the luggage compartment lid only when the doors are electronically unlocked and the vehicle is in PARK.

When using a programmed RKE transmitter, press the luggage compartment lid release button twice within 3 seconds to release the luggage compartment lid latch. The luggage compartment lid latch releases if the vehicle speed is 5 km/h (3.1 mph) or less.

The luggage compartment lid latch can also be released using a programmed passive key. Refer to Luggage Compartment Lid Passive Entry in this section.

RKE

The RKE feature is controlled by the BCM. When a button is pressed, the Transmitter Identification Code (TIC) and RKE command is received by the RTM. The RTM interprets the information and sends a message to the BCM over a LIN circuit, and when the network is awake over the CAN. If the BCM detects a programmed key, it carries out the command by controlling the door locks, releasing the luggage compartment lid latch or activating the horn or turn signals as required.

The RKE system can be used to:

unlock the driver door. unlock all doors. lock all doors. release the luggage compartment lid latch (luggage compartment lid release button must be pressed twice within 3 seconds). arm/disarm the perimeter alarm. activate/deactivate the panic alarm. global open the windows (press the unlock button and then within 10 seconds press and hold the unlock button for 3 seconds) (if equipped). global close the windows (press and hold the lock button for 2 seconds) (if equipped). remotely start the vehicle. configure the staged lock programming (2-stage unlock or global unlock).

The RKE transmitters have a normal operating range of 30 m (98 ft) in an open air, no obstruction environment.

The RKE transmitters and the BCM also utilize a rolling code to prevent the code from being captured by a code grabber. The system advances the counter in the RKE transmitter and the BCM every time a RKE transmitter button is pressed.

The message center displays Key Battery Low Replace Soon when the battery in the key needs to be replaced.

RKE Transmitter Unlock

The RKE feature provides a staged process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE feature unlocks only the driver door. If another unlock request is received within 3 seconds of the first, all the doors are unlocked. This feature can be disabled so that all the doors unlock on the first press of the unlock button (global unlock) using the message center settings.

Vehicles come from the factory set with the 2-stage unlock feature disabled (single press unlocks all doors).

RKE Transmitter Lock

The RKE feature requests all of the doors lock when the lock button is pressed.
