Headlights/Daytime Running Lights (DRL) Circuit Description

Battery voltage is applied continuously to the headlamp switch through circuit 2440. When the headlamp switch is in the HEAD position, the following conditions occur:
^ Voltage is applied to the headlamp dimmer switch.
^ Voltage is removed from circuit 306 which disengages the DRL control module.

When the headlamp dimmer switch is in the LOW position, battery voltage is applied to the following components through circuit 12:
^ The underhood accessory wiring junction block
^ The low beam headlamps

When the headlamp dimmer switch is in the HIGH position, battery voltage is applied to the following components through circuit 11:
^ The underhood accessory wiring junction block
^ The high beam headlamps
^ The instrument cluster
^ The instrument cluster head up display for the high beam indicator
