Daytime Running Lamp Control Unit: Description and Operation
GENERAL INFORMATION
The daytime running lamps are controlled by the Daytime Running Lamp Module (DRLM). The DRLM is located in the engine compartment on
the left fender wheelhouse. The DRLM allows the high beam headlamps to illuminate at a reduced intensity when the engine is running with the
headlamp switch OFF. The Daytime running lamps will go out when the headlamp switch is turned to the headlamps on position. The passing light
feature will flash bright high beams while the daytime running lamps are activated.
