REMOVAL
The Power Distribution Center (PDC) main housing unit, the PDC fuse wedges and the PDC bus bars cannot be repaired and are only serviced as a unit with the dash wire harness. If the PDC main housing unit, the fuse wedges or the bus bars are faulty or damaged, the entire PDC and dash wire harness unit must be replaced.

1. Disconnect and isolate the battery negative cable.
2. Disconnect each of the dash wire harness connectors. Refer to Connector Locations for the location of the dash wire harness connector locations.
3. Remove all of the fasteners that secure each of the dash wire harness ground eyelets to the vehicle body and chassis components. Refer to Connector Locations in the Wiring section for the location of the ground eyelet locations.
4. Disengage each of the retainers that secure the dash wire harness to the vehicle body and chassis components. Refer to Connector Locations in the Wiring section for the location of the dash wire harness retainer locations.
