Tail Lamp: Description and Operation

PARK, TAIL AND MARKER LAMPS

The park lamps, including the license lamps, are turned on when the headlamp switch is placed in the PARK or ON position or anytime the headlights are requested. The park lamps are also turned on with the fog lights. The fuse block - rear supplies battery positive voltage to the switch contacts of the PRK LP relay. When the headlamp switch is in PARK or in ON, the park lamp switch on signal circuit of the DIM has a ground path through the headlamp switch. The DIM provides battery positive voltage to the park lamp relay control circuit of the PRK LP relay. When the park lamps and/or the tail lamps are ON, the DIM energizes the PRK LP relay coil. This closes the switch contacts. Current flows from the PRK LP relay to the LH PARK LP and the RH PARK LP fuses. From the fuse, the current flows to the park lamps. The left park lamps are grounded at G103 and G402. The right park lamps and the right tail lamps are grounded at G103 and G401. The DIMR fuse supplies battery positive voltage to the license lamps and to the I/P lamp fuse supply voltage - 1 circuit of the DIM, for interior lamps backlighting. The license lamps are grounded at G401.
