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 All and A12. The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
