Power Distribution Center (PDC)

WARNING: This page is about a different variant/trim than selected.

The PDC is designed to provide centralized and convenient access to distribution of the electrical current required to operate all of the many standard and optional factory-installed electrical and electronic powertrain, chassis, safety, comfort and convenience systems. At the same time, these systems were designed to provide centralized locations for conducting diagnosis of faulty circuits and for sourcing the additional current requirements of many aftermarket vehicle accessory and convenience items. The PDC connects directly to the 12v Battery Positive (B+) cable.

The power distribution system also incorporates various types of circuit control and protection features, including:

Automatic resetting circuit breakers
Cartridge fuses
Blade fuses
Removable Relays
Non serviceable Printed Circuit Board (PCB) Relays

For charging of the low voltage system, the Power Pack Unit replaces the alternator charging output. The output from the PPU connects to the low voltage system through the PDC, just as the alternator does on a conventional charging system. The PPU output is protected by a larger amperage fuse typical used for the alternator output protection.
