WARNING: This page is about a different car, the 2010 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The Smart Junction Box (SJB) is also known as the Generic Electronic Module (GEM).
NOTE:
The SJB
-controlled time out for the battery saver relay and the accessory delay relay is 1 minute if the vehicle has less than 80 km (50 miles). Once the vehicle accumulates 80 km (50 miles), the time out for both relays is 10 minutes, as described in the Owner's Literature. Refer to
INTERIOR LIGHTING
for battery saver relay information. Refer to
GLASS, FRAMES AND MECHANISMS
for accessory delay relay information.
The SJB communicates via the Medium Speed Controller Area Network (MS-CAN).
The SJB controls the power door lock system. The SJB monitors the door lock/unlock switch inputs from the interior door lock switches. When the SJB receives an unlock/lock command from any door lock control switch, the module activates the door lock actuators. Refer to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS .
The SJB also controls the following remote lock/unlock features:
- Remote Keyless Entry (RKE) transmitter lock/unlock
- Panic alarm
The SJB receives inputs and provides outputs for the exterior and interior lighting, front and rear wipers, warning chimes/lamps, and has an integrated Tire Pressure Monitoring System (TPMS).
