Normal Operation

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

The instrument cluster communicates interactively with other electronic modules using the communication networks. With the ignition switch in the START/RUN position, the instrument cluster receives power from central junction box (CJB) fuse 28 (5A), circuit 640 (RD/YE) and CJB fuse 27 (5A), circuit 1003 (GY/YE). When in the RUN/ACC position, power is received from CJB fuse 1 (10A), circuit 489 (PK/BK). With the ignition switch in the OFF position, the instrument cluster receives its keep-alive power from CJB fuse 21 (15A), circuit 3049 (BK/LG). The instrument cluster grounding is accomplished through circuit 875 (BK/LB) and the bulb grounding is accomplished through circuit 57 (BK).
