Normal Operation

WARNING: This page is about a different car, the 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster communicates interactively with the diagnostic tool and other electronic modules using the controller area network (CAN). With the ignition switch in the START or RUN position, the instrument cluster receives voltage from the central junction box (CJB) fuse 45 (10A) through circuit 640 (RD/YE). When the ignition switch is in the RUN or ACC position, voltage is received from CJB fuse 33 (15A) through circuit 1002 (BK/PK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive voltage from CJB fuse 2 (10A) through circuit 3049 (BK/LG). The instrument cluster grounding is through circuit 676 (PK/OG) and circuit 57 (BK).
