8W-97 POWER DISTRIBUTION - SERVICE INFORMATION

MODULE-INTEGRATED POWER

DESCRIPTION

The Integrated Power Module (IPM) is a combination

of the Power Distribution Center (PDC) (1) and the

Front Control Module (FCM) (2). The IPM is located in

the engine compartment, next to the battery. The

power distribution center mates directly with the (FCM)

to form the IPM. The (PDC) is a printed circuit board

based module that contains fuses and relays, while

the FCM contains the electronics controlling the IPM

and other functions. The IPM connects directly to the

battery positive via a stud located on top of the unit.

The ground connection is via electrical connectors.

The IPM provides the primary means of voltage distri-

bution and protection for the entire vehicle.

All of the current from the battery and the generator output enters the integrated power module via a stud on the top

of the module. Internal connections of all of the power distribution center circuits is accomplished by a combination

of bus bars and a printed circuit board.
