Daytime Running Lamp: Description and Operation

DAYTIME RUNNING LAMPS (CANADA ONLY)

Vehicles built for use in Canada are equipped with a Daytime Running Lamp (DRL) system. The DRL system operates the high beam filaments at a lower intensity when the engine is operating and the exterior lamp switch is in either the OFF or parking lamp ON position and the parking brake is not applied. The DRL system is controlled by the Cab Compartment Node (CCN), or instrument cluster. The DRL overrides the headlamp switch when the headlamps are turned OFF. The headlamps operate normally when the headlamps are turned ON. DRL's are standard equipment on vehicles manufactured for sale in Canada. Vehicles with DRL illuminate the high beam filament of each headlamp bulb at a reduced intensity to serve as the DRL.
