Instrument Panel Integration Module (IPM)

Battery voltage is provided from the underhood fuse block to the IPM. Ignition voltage is provided from the rear fuse block to the IPM. The voltage inputs are referenced to the module ground. The IPM is wired to the class 2 serial data line. The various IPM input and output circuits are described in the corresponding functional areas as indicated on the IPM electrical schematics.

The IPM functions include the following functions:
^ Ambient light sensor input and twilight delay input for headlights control
^ Front HVAC air delivery and temperature controls
^ I/P dimmer switch input
^ Ignition switch headlight control
^ Interior lamps switch input
^ Key in ignition switch input from the ignition switch
^ Rear compartment lid release switch input
