Normal Operation
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
With the ignition in the START or RUN mode, the Instrument Panel Cluster (IPC) receives voltage from the Smart Junction Box (SJB) fuse 29 (5A). With the ignition in the OFF mode, the IPC receives its keep-alive voltage from the SJB fuse 26 (10A). The IPC grounding is through a single ground. The IPC sets DTC U300A:62 in continuous memory and on-demand if the RUN/START input is open or if the SJB fuse 29 (5A) has failed.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- IPC
