With Daytime Running Lights (DRL)

The HEADLAMPS receive battery voltage through the H/L LH and H/L RH Fuses at all times. When the Light Switch is in the HEAD position, a ground is provided through the DAYTIME RUNNING LIGHTS (DRL) CONTROLLER, the JUNCTION BLOCK, and the Dimmer Switch/Light Switch at G203. When the Light Switch is in the "OFF" or the PARK position, a ground is provided through the DAYTIME RUNNING LIGHTS (DRL) RESISTOR at G200 provided that all conditions for Daytime Running Lights operation are met.

The system operates the low-beam HEADLAMPS at a lower intensity than the vehicle's regular low beams. Daytime Running Light system operation is initiated when the DRL CONTROLLER senses the following:

^ A charge signal from the GENERATOR (indicating an "engine running" condition) at terminal 5.

^ No ground signal from the PARKING BRAKE SWITCH (indicating that the parking brake is not engaged) at terminal 4.

^ A lights "OFF" signal (indicating the Light Switch is in the "OFF" or PARK position) at terminal 11.

High and low-beam selection is provided by grounding the high and low-beam filaments separately. The high-beam filaments are grounded through the Dimmer Switch at G203. The low-beam filaments are grounded through the DRL CONTROLLER, JUNCTION BLOCK, Dimmer Switch, and the Light Switch at G203.

The DRL CONTROLLER receives battery voltage from system operation at terminal 7 from the IG Fuse whenever the ignition switch is in the "ON" or "START" position. The DRL CONTROLLER is permanently grounded at G203 from terminal 8.
