Daytime Running Lamps (DRL)

NOTE: If the vehicle is equipped with DRL (Daytime Running Lamps), the BCM (Body Control Module) is configured for this feature.

The DRL (Daytime Running Lamps) system utilizes the existing circuitry and components from the headlamp system and operates the low beam headlamps at a reduced intensity.

The BCM (Body Control Module) monitors the ignition status (ignition switch for vehicles without IA (Intelligent Access) or the start/stop switch for vehicles with IA (Intelligent Access)), the headlamp switch and autolamp status.

Based on the input, the BCM (Body Control Module) activates the DRL (Daytime Running Lamps).

The DRL (Daytime Running Lamps) are activated when the ignition is in RUN and the low beams have not been turned on by the autolamp system or the headlamp switch.
