Power Distribution Center (PDC) - Operation

OPERATION

The power distribution center (PDC) is located in the engine compartment, next to the battery and connects directly to the B+ cable via a power stud located at the front of the unit, on the upper left corner of the fuse/relay block. The PDC contains fuses and relays for power distribution and circuit protection.

The PDC includes three types of fuses for circuit protection. A row with 14 MINI blade-type fuses is used for the protection of relay-controlled body electrical circuits. The MINI fuse current ratings range from 5A to 20A. A separate row with three MINI fuses is used to supply power to the powertrain control module (PCM). Two ATO blade-type fuses supply power to the blower motor (40A) and the power outlet (30A). A row with ten MAXI blade-type fuses is used for protection of the main power supply circuits. The MAXI fuse current ratings employed range from 20A for the ignition switch to 70 A for the electric power steering (EPS) system. Power from the PDC is supplied to the body control module (BCM) through a 60A MAXI fuse.
