Module Controlled Functions: Notes
WARNING: This page is about a different car, the 2009 Ford Econoline. 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).
The SJB is the only multifunction electronic module on this vehicle.
NOTE:
Junction Box (SJB) NOTE: The time out for the battery saver relay and the accessory delay relay (both are controlled by the SJB
) is one minute if the vehicle has less than 80 km (50 miles). Once the vehicle passes the approximate mileage threshold of 80 km (50 miles), the time out for both relays is 10 minutes, as described by the Owner's Literature. For the battery saver relay, refer to
INTERIOR LIGHTING
. For the accessory delay relay, refer to
GLASS, FRAMES AND MECHANISMS
.
The SJB controls and provides diagnostic information for the following:
- Autolamps
- Battery saver function
- Delayed accessory function
- Exterior lighting
- Horn
- Interior lighting
- Power door locks
- Remote Keyless Entry (RKE) system/keyless entry keypad
- Tire Pressure Monitoring System (TPMS)
The SJB controls multiple vehicle systems including:
- Locking and unlocking all of the doors
- Panic alarm function (horn sounding and parking lamps flashing intermittently in regular intervals)
- Single horn chirp confirmation when the lock button is pressed on the RKE transmitter twice within 3 seconds and all of the doors are closed, double horn chirp confirmation if one or more doors are open
- Single flash of the parking lamps when the lock button is pressed on the RKE transmitter with all of the doors closed. There is no parking lamp flash if the RKE transmitter LOCK button is pressed and one or more doors are ajar
- Turning on the interior lamps when the doors are unlocked using an RKE transmitter
- TPMS
The SJB also monitors the door ajar signals to determine if a single or double horn chirp confirmation is necessary when locking the doors using the RKE transmitter. Also, if all of the doors are closed and the doors are locked using the RKE transmitter, the SJB turns off the interior lamps. If one or more doors are detected open by the door ajar switches, the SJB will not turn off the interior lamps.
