REMOVAL
The Power Distribution Center (PDC) is serviced as a unit with the engine compartment wire harness. If any internal circuit of the PDC or the PDC housing is faulty or damaged, the entire PDC and engine compartment wire harness unit must be replaced.
1. Disconnect and isolate the battery negative remote cable.
2. Disconnect each of the engine compartment wire harness connectors. (Refer to ELECTRICAL/ WIRING DIAGRAM INFORMATION - DIAGNOSIS AND TESTING) for more information on the locations of the affected connectors.
3. Remove the fasteners that secure each of the engine compartment wire harness ground eyelets to the vehicle body and chassis components. (Refer to ELECTRICAL/WIRING DIAGRAM INFORMATION - DIAGNOSIS AND TESTING) for more information on the ground eyelet locations.
4. Disengage each of the retainers that secure the engine compartment wire harness to the vehicle body and chassis components. (Refer to ELECTRICAL/WIRING DIAGRAM INFORMATION - DIAGNOSIS AND TESTING) for more information on the retainer locations.
5. Remove one PDC mounting screw and disengage the PDC housing by pushing the locking tabs in on the PDC base. The mounting bracket blades are retained by a snap fit in the PDC mounting slots.
6. Remove the PDC and the engine compartment wire harness from the engine compartment as a unit.
INSTALLATION
The Power Distribution Center (PDC) is serviced as a unit with the engine compartment wire harness. If any internal circuit of the PDC or the PDC housing is faulty or damaged, the entire PDC and engine compartment wire harness unit must be replaced.
NOTE: If the power distribution center (PDC) is being replaced with a new unit, be certain to transfer each of the fuses, fuse cartridges, fusible links and relays from the old power distribution center to the proper cavities of the new power distribution center. Refer to Electrical, Wiring Diagram Information for the proper power distribution center cavity assignments.
1. Position the PDC over the mounting bracket in the engine compartment.
2. Align the PDC mounting slots with the blades on the PDC mounting bracket.
3. Push down firmly and evenly on the PDC housing until it snaps into place on the PDC mounting bracket.
4. Route the engine compartment wire harness from the PDC through the engine compartment, engaging each of the harness retainers to the mounting provisions in the vehicle body and chassis components. Make sure to make clip attachment into the rail located behind the PDC. (Refer to ELECTRICAL/WIRING DIAGRAM INFORMATION - DIAGNOSIS AND TESTING) for more information on the harness routing and retainer locations.
5. Install and tighten the fasteners that secure each of the engine compartment wire harness ground eyelets to the vehicle body and chassis components. (Refer to ELECTRICAL/WIRING DIAGRAM INFORMATION - DIAGNOSIS AND TESTING) for more information on the ground eyelet locations.
6. Reconnect each of the engine compartment wire harness connectors. (Refer to ELECTRICAL/WIRING DIAGRAM INFORMATION - DIAGNOSIS AND TESTING) for more information on the locations of the affected connectors.
7. Torque nut retaining positive battery cable at PDC to 96 - 141 N.m (85 - 130 in. lbs.).
8. Reconnect the battery negative remote cable.
