DESCRIPTION
The Integrated Power Module (IPM) is mounted in the engine compartment, next to the battery. The IPM houses all fuses and relays for the vehicle.
Fuse and relay information is laser etched inside surface of the hinged cover. As well as housing fuses and relays, the IPM is an electrical control and interface center in the engine compartment. It provides and distributes information to the rest of the vehicle. The IPM controls the following features
All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is mounted in an asymmetrical holder within the Integrated Power Module (IPM). Prior to delivery to the customer, this fuse is positioned (shipping mode) for the "always on" equipment only when the ignition is in the ON position. This avoids long term drain on the battery during shipping and storage. The IOD fuse will be aligned with the other fuses on the same row it is in when in the shipping mode. Dealer personnel are to reverse the IOD fuse to "customer mode" by rotating the asymmetrical fuse holder (with the IOD fuse in it) 180 degrees in its position to switch these features to battery power just prior to new vehicle delivery. The fuse will NOT be aligned to the other fuses in the row it is in when it is in the customer mode. When a replacement IPM is installed in the vehicle, the IOD fuse must be rotated to the "customer" position.
OPERATION
The term ignition-off draw identifies a normal condition where power is being drained from the battery with the ignition switch in the Off position. The IOD fuse feeds the memory and sleep mode functions for some of the electronic modules in the vehicle as well as various other accessories that require battery current when the ignition switch is in the Off position, including the clock. The only reason the IOD fuse is reversed in its holder is to reduce the normal IOD of the vehicle electrical system during new vehicle transportation and pre-delivery storage to reduce battery depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and moved as needed by both vehicle transportation company and dealer personnel.
This vehicle is equipped with four electrical power outlets. Two are located in the instrument panel center stack, one in the rear of the center console and one in the left quarter trim panel behind the rear seats.
One instrument panel and the center console outlet are battery powered - on at all times. The other outlets receive power only when the ignition is ON. The ignition powered instrument panel outlet will accept a cigar lighter element.
The operator can choose to make the ignition powered left rear quarter panel outlet battery powered by repositioning a fuse in the Integrated Power Module (IPM).
All outlets include tethered caps with ISO "battery" or "key" icons indicating whether they are battery or ignition powered.
