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) monitors the driver door disarm switch on circuit 1313 (LB/BK). The disarm signal occurs when the driver door lock key cylinder is turned to unlock causing the driver door disarm switch to complete the circuit through circuit 1205 (BK). This signals the SJB to cancel the alarm function.
