Handles, Locks, Latches and Entry Systems - Vehicles With: One-Touch Open and Close Front Windows - System Operation and Component Description: RKE: Notes

The RKE feature is controlled by the BCM. When a button is pressed (IKT or passive key), the 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 or activating the horn or turn signals as required.

The RKE system can be used to:

• unlock the doors (configurable).
• lock all the doors.
• enable the liftgate release switch (located on the liftgate) for 45 seconds.
• arm/disarm the perimeter alarm (if equipped).
• activate/deactivate the panic alarm.
• provide a visual confirmation when the unlock button is pressed (a long flash of the turn signals).
• provide an audible confirmation when the lock button is pressed twice within 3 seconds with all the doors closed (sounds the horn once).
• will not provide an audible confirmation when the lock button is pressed twice within 3 seconds and any door is ajar or a door is not locked (horn will not sound).
• remotely start the vehicle (if equipped).

The RKE transmitters for a IKT and passive key have a normal operating range of 30m (98.43ft) in an open air, no obstruction environment.

The RKE transmitters and the BCM 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.
