The IC controls the alarm indicator which is incorporated in the main display in the IC.

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

Alarm Indicator 

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

Operation of the alarm indicator is controlled by the IC which varies the flash rate of the LED to indicate the system status of the alarm systems.
