Lighting System Indicators

HIGH BEAM
The high beam indicator is hard wired to the headlamp switch. The high beam indicator illuminates when the headlamp switch is in the high position (signal circuit is low).

TURN SIGNALS
The left and right turn signal indicators are hard wired to the turn signal switch and the hazard switch. The turn signal indicator illuminates when the turn signal lamps supply voltage circuit is active. The Body Control Module (BCM) is also hard wired to the turn signal switch. If the BCM determines that the turn signal flasher signal circuit is active for more than 1.2 km (0.75 mile), the BCM activates an audible warning.

DRIVER CONTROLS AND MODULES
The Body Control Module (BCM) module processes the inputs and the controls. The ambient light sensor supplies the BCM with a signal for daytime conditions or for low light conditions.
