MODULE-TOTALLY INTEGRATED POWER
DESCRIPTION
All of the electrical current distributed throughout this vehicle is directed through the standard equipment Totally Integrated Power Module (TIPM). 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 layout label affixed to the inside surface of the cover to ensure proper component identification.
The TIPM housing is secured to the TIPM mounting bracket by three clips integral to the TIPM housing. All of the TIPM outputs are through the integral engine compartment wire harness.
OPERATION
All of the current to the Totally Integrated Power Module (TIPM) comes directly from the positive battery cable to a stud located on the bottom of the TIPM. The cable is secured to the TIPM stud with a nut. 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 fuses and TIPM housing assembly are available for service replacement.
REMOVAL
1. Open hood.
2. Disconnect and isolate the battery negative cable.
3. Disconnect each of the Totally Integrated Power Module (TIPM) wire harness connectors.
4. Remove the TIPM positive cable retaining nut and remove the cable from the stud.
5. Depress the three mounting clips to disengage and remove the TIPM housing from its mounting bracket.
6. Remove the TIPM from the vehicle.
INSTALLATION
CAUTION: The original Cab Compartment Node (CCN) and Powertrain Control Module (PCM) must be installed and functioning properly prior to powering up the new Totally Integrated Power Module (TIPM). The TIPM receives vehicle configuration data from the CCN and Vehicle Identification Number information from the PCM. If configuration information becomes lost or corrupted, the data can be obtained from DealerCONNECT
1. Position the TIPM onto the mounting bracket and push down until the mounting clips are fully seated.
2. Position the TIPM positive cable onto the mounting stud and install the retaining nut. Torque nut 9 - 11 N·m (80 - 100 in. lbs.).
3. Connect each of the TIPM wire harness connectors.
4. Remove TIPM cover and fully seat the Airbag fuse holder (two fuses in one yellow carrier). Fully seat the Ignition Off Draw (IOD) fuses (two fuses in a white/natural carrier).
5. Connect the battery negative cable.
6. Close hood.
7. Insert the ignition key and turn it to the “RUN” position and wait twelve seconds. The TIPM will collect the necessary vehicle configuration and VIN data from the CCN and PCM at this time. After twelve seconds turn the ignition key to the “OFF” position and then back to the “ON” position and verify proper vehicle systems operation.
