Installing


The original Cab Compartment Node and Powertrain Control Module must be installed and functioning properly prior to powering up the new 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 through the StarSCAN.

- Position the TIPM into the engine compartment.






- Connect the electrical wire harness connectors.

- Position the positive cable onto the TIPM stud and install the nut. Tighten the nut to 11 Nm (97 in lbs).

- Position the TIPM onto the bracket and push down until the mounting clips are fully seated.

- Open the TIPM cover and fully seat the airbag fuse holder and the ignition off draw fuse.

- Connect the negative battery cable. Refer to => [ Battery, Disconnecting and Connecting ] Tools and Equipment.

- Close the hood.

- 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.
