Exterior Lights Circuit Description

The Dash Integration Module (DIM) supplies battery positive voltage (B+) to the PRK LP relay coil when the headlamps or park lamps need to be on or when the ignition switch is in the ON position. Battery positive voltage (B+) is supplied at all times to the PRK LP relay switch. When the park lamps are to be active, the DIM grounds the PRK LP relay coil. The coil is energized, closing the switch contacts. Battery positive voltage (B+) is supplied to the rear fuse block LP PK R Fuse, LP PK L Fuse, and DIMR Fuse. The LP PK R Fuse supplies battery positive voltage (B+) to the RH park lamps. The LP PK L Fuse supplies battery positive voltage (B+) to the LH park lamps. The LH and RH park lamps are permanently grounded, so all park lamps have power and ground, and then light. The DIMR Fuse supplies battery positive voltage (B+) to the DIM Park Lamp input for interior lamps dimming, the license lamps, the underhood lamp, and the cornering lamp. The license lamps are permanently grounded, so both license lamps have power and ground, and then light.
