Instrument Cluster

The Body Control Module/Gateway Module (BCM/GWM) controls the security system status indicator which is incorporated in the main display in the Instrument Cluster (IC).

The IC also controls the engine immobilization, in conjunction with the BCM/GWM, the Powertrain Control Module (PCM) and the Anti-Lock Brake System (ABS) control module. The PCM controls the engine crank and fuel functions and the ABS control module controls the tilt function. The PCM and ABS control module communicate to each other after the BCM/GWM processes the valid smart key information.

Security System Status Indicator 

The security system status indicator is a red Light Emitting Diode (LED) located in the Instrument Cluster (IC). When the ignition is switched off, the indicator gives a visual indication of the active anti-theft system to show if the alarm system is set or unset.

In Power Mode 6 (Ignition ON), the security system status indicator provides a visual indication of the status of the passive anti-theft (engine immobilization) system. If the immobilization system is operating correctly, the LED will be illuminated for 3 seconds after the ignition is switched on and then extinguish.

If a fault exists in the immobilization system, the LED will be either permanently illuminated or flashing for 60 seconds. This indicates that a fault exists and a Diagnostic Trouble Code (DTC) has been recorded. After the 60 second period, the LED will flash at different frequencies which indicates the nature of the fault.

Operation of the security system status indicator is controlled by the IC. The IC varies the flash rate of the LED to indicate the system status of the alarm and the immobilization systems.

Operation of the security system status indicator is also controlled by the Body Control Module/Gateway Module (BCM/GWM).
