Dash Integration Module (DIM)
Battery positive voltage (B+) is provided from IGN SW fuse 20 in the rear fuse block on CKT 540 (ORN) to the DIM at connector C3 terminal G. The module ground is on connector C3 terminal E, which is wired to ground G201 by CKT 451 (BLK/WHT). Battery positive sense voltage is provided from DIM fuse 39 in the rear fuse block to the DIM at connector C1 terminal A12 on CKT 3340 (ORN). This battery input is referenced to the ground sense input at DIM connector C1 terminal B12, which is wired to the battery negative terminal and to ground G307 on CKT 51 (BLK/WHT) and CKT 50 (BLK). These sense inputs 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 CKT 1807 (PPL) at connector C2 terminals A11 and A12. 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 positive voltage (B+) is provided from I/P fuse 7 in the underhood fuse block on CKT 440 (ORN) to the IPM at connector C1 terminal C1. Ignition positive voltage (IGN3) is provided from the IGN3 RR fuse 6 in the rear fuse block to the IPM on CKT 41 (BRN) at connector C1 terminal C2. The voltage inputs are referenced to the module ground at connector C1 terminal D16 on CKT 451 (BLK/WHT). The IPM is wired to the Class 2 serial data line CKT 1807 (PPL) at connector C1 terminals C7 and C8. The various IPM input and output circuits are described in the corresponding areas as indicated on the IPM electrical schematics.
Rear Integration Module (RIM)
Battery positive voltage (B+) is provided from IGN SW fuse 20 in the rear fuse block on CKT 540 (ORN) to the RIM at connector C1 terminal A1. Ignition positive voltage (IGN1) is provided from IGN1 fuse 12 in the rear fuse block on CKT 1039 (PNK) at RIM connector C1 terminal A3. These voltage inputs are referenced to module ground at connector C1 terminals B7 and B8 on CKTs 1051 (BLK). The RIM is wired to the Class 2 serial data line CKT 1807 (PPL) at connector C2 terminals B3 and B4. The various RIM inputs and outputs are described in the corresponding functional areas as indicated on the RIM electrical schematics.
