Diagnostic Routine K

Diagnostic Overview

An Individual Button/Feature Is Inoperative From The Remote Keyless Entry (RKE) Transmitter

Normal Operations and Fault Conditions

The remote locking and unlocking of the doors, releasing the liftgate or luggage compartment lid latch, or activation of the panic alarm is accomplished by the BCM (Body Control Module) receiving a command message from the RKE (Remote Keyless Entry) transmitter. The BCM (Body Control Module) processes the command and provides the appropriate output.

The BCM (Body Control Module) disables the panic feature if the ignition key is in any position other than OFF or LOCK.
