Normal Operation

WARNING: This page is about a different car, the 2005 Mercury Montego, 2005 Ford Freestyle, and 2005 Ford Five Hundred. However, it is still accessible from the selected car via links, so may be relevant.

The smart junction box (SJB) receives voltage for the power locks on circuit 906 (RD/OG). The door lock actuators are powered through the SJB by fuse 3 (25A). The SJB energizes the lock or unlock relays based upon input from the door lock switches, the remote keyless entry (RKE) transmitter, or the RKE keypad. If the SJB energizes circuit 1088 (PK/WH) the door lock actuators unlock the doors and the liftgate (wagon). If the SJB energizes circuit 1763 (PK/BK) the door lock actuators lock the doors and the liftgate (wagon).
