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.
