Normal Operation

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

The Remote Keyless Entry (RKE) feature is controlled by the Tire Pressure Monitor (TPM) module and the Body Control Module (BCM). When a button is pressed on an Integrated Keyhead Transmitter (IKT) the Transmitter Identification Code (TIC) and RKE command is received by the internal TPM module antenna. If the TPM module determines that it is a valid and programmed TIC , it sends the RKE command and TIC to the BCM over the Medium Speed Controller Area Network (MS-CAN). When the BCM receives the RKE command, it carries out the command by controlling the door locks or activating the horn and turn signals for the panic alarm.

The BCM disables the panic feature if the ignition key is in any position other than OFF or LOCK.

This pinpoint test is intended to diagnose the following:

Door locks
Factory remote start system (if equipped)
Horn system
Power liftgate release (if equipped)
Turn signal system
IKT
