Code B2A25 Ford Description

The Smart Junction Box (SJB) sends voltage signals to the door lock control switches through the lock and unlock input circuits. When the lock or unlock switch is pressed, the corresponding voltage signal is routed to ground, signaling the SJB to lock or unlock the doors. The door lock control switches have a dedicated ground circuit. The Diagnostic Trouble Code (DTC) sets when the SJB detects a short to ground from the lock or unlock request input circuits. This DTC may also set if either of the door lock control switches are pressed for longer than 2 minutes.
