Daytime Running Lamp: Description and Operation
DAYTIME RUNNING LAMPS (DRL)
The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the
outside (ambient) light level. When the BCM receives this signal, it will either turn ON the daytime running lamps (DRL) or the headlamps for auto
headlamp operation. Any function or condition that turns ON the headlights will cancel the DRL operation. With the headlight switch in the AUTO
position, the headlights will either be turned ON or OFF, after an approximate 8 second delay depending on whether daylight or low light conditions are
sensed. When the ambient light sensor signals the BCM for DRL operation in daylight conditions, the BCM illuminates the front turn signal lamp bulbs
at a constant rate. The DRL will operate when the ignition switch is in the RUN position, the headlamp and panel dimmer switch is in the AUTO
position, the gear selector is not in the PARK position, and the parking brake is released. When these conditions have been met and the ambient light
sensor indicates daytime conditions, the DRL will illuminate.
DRL operation can be temporarily disabled by momentarily placing the headlamp switch in the OFF position. This will cancel DRL operation until the
switch is momentarily placed in the OFF position again or until the next ignition key cycle occurs. Canadian requirements prohibit disabling DRL
operation therefore the Canadian export vehicles are not equipped with the DRL defeat feature.
