Daytime Running Lamp: Description and Operation
DAYTIME RUNNING LAMPS (DRL)
The ambient light sensor is a light sensitive transistor that varies its signal to the body control module (BCM) in response to changes in the outside
ambient light level. Any function or condition that turns ON the headlamps will cancel daytime running lamp (DRL) operation. With the headlamp
switch in the OFF position, activating automatic lamp control (ALC), the front turn signal lamps will be turned ON after a 30-second delay under
daylight conditions, which is determined by the ambient light sensor signal to the BCM. The DRL operates when the ignition switch is in the RUN
position, the front wipers are not activated, and the transmission is not in PARK. When these conditions have been met and the ambient light sensor
indicates daylight conditions, the BCM will illuminate the front turn signal lamps ON steady.
