The body control system consists of three modules, the dash integration module (DIM), the instrument panel module (IPM), and the rear integration module (RIM).
Dash Integration Module (DIM)
Battery voltage is provided from the rear fuse block to the DIM. The module ground is wired to ground. Battery positive sensor voltage is provided from the rear fuse block to the DIM. This battery signal is referenced to the ground sensor signal at DIM which is wired to the battery negative terminal and to ground. These sensor signals are physically connected to the battery positive and negative terminals for accurate battery voltage readings. The DIM is wired to the class 2 serial data line. The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
Instrument Panel 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.
Rear Integration Module (RIM)
Battery voltage is provided from the rear fuse block to the RIM. Ignition voltage is provided from the rear fuse block to the RIM. These voltage inputs are referenced to module ground. The RIM is wired to the class 2 serial data line. The various RIM input and output circuits are described in the corresponding functional areas as indicated on the RIM electrical schematics.
