Power and Ground Distribution: Service and Repair

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.

REMOVAL

Battery Negative:

1. Open hood then disconnect and isolate the battery negative remote cable from the remote terminal on the left shock tower.
2. Remove the Air Inlet System (housing and resonator).
3. Disconnect each of the engine compartment wire harness connectors.
4. Remove the fasteners that secure each of the engine compartment wire harness ground eyelets to the vehicle body and chassis components.
5. Disengage each of the retainers that secure the engine compartment wire harness to the vehicle body and chassis components.
6. Remove the three screws retaining the PDC to its mounting bracket.
7. Remove the PDC and the engine compartment wire harness from the engine compartment as a unit.

INSTALLATION

NOTE: If the power distribution center 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.

1. Position the PDC over the mounting bracket between the Powertrain and Transmission Control Modules in the engine compartment.
2. Align the PDC mounting slots with the blades on the PDC mounting bracket.
3. Install the three mounting screws into the PDC.
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.
5. Install and tighten the fasteners that secure each of the engine compartment wire harness ground eyelets to the vehicle body and chassis components.
6. Reconnect each of the engine compartment wire harness connectors.
7. Reconnect the battery negative remote cable to the remote terminal on the left strut tower.
