DESCRIPTION
All of the electrical current distributed throughout this vehicle is directed through the standard equipment Totally Integrated Power Module (TIPM) (1).
The molded plastic TIPM housing is located in the left front corner of the engine compartment, just behind the air cleaner housing and the battery. The
TIPM housing has a molded plastic cover. The TIPM cover is easily removed for service access and has a convenient fuse and relay layout label affixed
to the inside surface of the cover to ensure proper component identification.
The TIPM housing is secured to the left inner fender well an indexing pin and one screw. All of the TIPM outputs are through the integral engine
compartment wire harness.
Operation
OPERATION
All of the current from the generator cable connection goes to the battery through a 10 gauge fusible link that is secured with a nut to the positive battery
terminal at the starter. Internal connection of all the Totally Integrated Power Module (TIPM) circuits is accomplished by an intricate network of hard
wiring and bus bars. Refer to Wiring Diagrams for complete circuit diagrams.
The fusible link, fuses and relays are available for service replacement. The TIPM unit cannot be repaired and is only serviced as a unit with the engine
compartment wire harness. If the TIPM is inoperative or damaged, the engine compartment wire harness assembly must be replaced.
