Functional Description - Power Distribution Center (PDC)

The PDC is designed to provide safe, reliable, 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 Battery Positive (B+) cable.

The power distribution systems also incorporate 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

The charging system is protected by a larger amperage fuse that is typically in the fuse array attached to the PDC.
