Daytime Running Lamp Module

On Canadian models, the instrument panel dimming module and Daytime Running Lamps (DRL) module are the same. The Instrument Panel Dimming/DRL module operates the low beams of the headlamps when the ignition is in the RUN position.

In the RUN position, the ignition switch connects circuit A2 from fuse 13 in the Power Distribution Center (PDC) to circuit A22. Circuit A22 supplies power to circuit F83 through fuse 19 in the fuse block. Circuit F83 splices to the Instrument Panel Dimming/DRL module.

Circuit L26 from the headlamp switch also connects to the Instrument Panel Dimming/DRL module.

Circuit L4 powers the low beams of the left and right headlamps. When the headlamp switch is OFF, the Instrument Panel Dimming/DRL module powers the low beams on circuit L4. When the headlamps are ON, the dimmer switch in the multi-function switch powers the low beams on circuit L4.

Circuit L3 feeds the high beams of the headlamps. When the operator flashes the headlamps with the stalk of the multi-function switch, the DRL senses voltage on circuit L3. When it senses voltage on circuit L3, the Instrument Panel Dimming/DRL module stops supplying power to the low beams on circuit L4.

Circuit Z1 provides ground for the Instrument Panel Dimming/DRL module.
