Marker Lamp: Description and Operation

PARK, TAIL, LICENSE 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 front 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 dash integration module (DIM) has a ground path. 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 park lamp relay control circuit. This closes the switch contacts. Current flows from the PRK LP relay to the LP PK L fuse and to the LP PK R fuse. 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 G401. When the park lamps are activated the PRK LP relay supplies battery positive voltage through the DIMR fuse to the license lamps and to the instrument panel lamp fuse supply voltage - 1 circuit of the DIM, for interior lamps dimming. The license lamps are grounded at G401.
