Daytime Running Lamp Control Unit: Description and Operation
The Daytime Running Lights (Headlamps) System is installed on vehicles manufactured for sale in Canada only. A separate module, mounted on the
cowl, controls the DRL.
The headlamps are illuminated when the ignition switch is turned to the ON position. The DRL module receives a vehicle-moving signal from the
vehicle speed sensor. This provides a constant headlamps-on condition as long as the vehicle is moving. The lamps are illuminated at less than 50
percent of normal intensity.
