Instrument Panel Integration Module (IPM)

Battery Positive Voltage (B+) is provided from I/P fuse 7 in the Fuse Block - Underhood to the IPM. Ignition Positive Voltage (IGN3) is provided from the IGN3 RR fuse 6 in the Fuse Block - Rear to the IPM. The voltage inputs are referenced to the module ground. The IPM is wired to the Glass 2 serial data line. The various IPM input and output circuits are described in the corresponding areas as indicated on the IPM electrical schematics.

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