Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The smart junction box (SJB) energizes the lock or unlock relays based upon input from the RKE keypad. The RKE keypad uses circuits CPK29 (GY/BU), CPK30 (VT/GN) and CPK31 (YE/GN) to send signals to the SJB by grounding the selected circuit through the RKE keypad on circuit GD126 (BK/WH). The SJB locks or unlocks the doors based on RKE keypad input.
