Integrated Power Module (IPM): Notes

The Integrated Power Module (IPM) is an electrical control and interface center located in the engine compartment. The IPM houses in one module what is known in other vehicles as the Power Distribution Center and the Front Control Module. The IPM, with its fuses and relays provides power and signal distribution throughout most of the vehicle. The IPM receives both hard wire and digital electronic inputs from the vehicle electrical system. Based on these inputs and the ignition switch position, it provides direct power feeds and relay control to some of the vehicles' most critical electrical systems.
