Exterior Lighting System
EXTERIOR LIGHTING SYSTEM
Exterior Lighting Battery Saver
The BCM monitors the status of and controls the park lamp, head lamp and fog lamp relay's. If any exterior lamps are left on after the ignition is turned off; the BCM will turn them off after 10 minutes.
Headlamp Delay
The headlamp time delay operates when the ignition switch is turned off while the headlamps are still on, and the headlamps are then turned off within 45 seconds after the ignition is off. This will provide a 90-second time delay before turning off the headlamps.
Headlamp Switch
The headlight switch on LH vehicles use a multiplexed (MUX) circuit to the BCM. The BCM will then control the park lamp, head lamp and fog lamp relay's based on this input.
Fog Lamp Control
The body control module controls the operation of the fog lamp relay which controls the fog lamps. The fog lamps can only be on if the park or low beam headlamps are on. If the high beams are turned on, the fog lamps will automatically be turned off.
Auto Headlamps
The headlamps and park/tail lamps will be activated by the BCM when the headlamp switch is in the auto mode. To activate the auto headlamps the BCM requires that: (1) the headlamp switch is in the 'A position, (2) the engine is running, and (3) the light level sensed through the sun load sensor falls below the calibrated level.
