Circuit Description (Export)

The taillamps, headlamp position lamps, and license lamps, are turned on when the headlamp switch is placed in either the PARK or HEAD position, or anytime the headlights are requested. With the headlamp switch placed in the OFF position, and the engine running, the Daytime Running Lamps (DRL) control module will operate the taillamps. The PARK fuse supplies battery voltage to the headlamp switch and DRL module. Current flow is from the headlamp switch to the headlamp position lamps and license lamps. The taillamps receive the headlamp switch voltage via an inactive DRL control module. For DRL operation current flow is from the DRL control module to the taillamps only. The LF headlamp position lamp is grounded at G101 and the RF headlamp position lamp is grounded at G102. The remaining lamps are grounded a G401.
