Smart Junction Box (SJB)
WARNING: This page is about a different car, the 2005 Mercury Sable and 2005 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
The SJB receives inputs from the following:
- door ajar switches
- liftgate ajar switch (wagon)
- liftgate glass switch (wagon)
- headlamp switch
- remote keyless entry (RKE) transmitter/keyless entry keypad switches
- powertrain control module (PCM) (vehicle speed signal)
- ignition switch
The SJB uses these inputs to control the output to the battery saver relay, interior lamp relay and the approach lamp relay. Both relays are integral to the SJB and cannot be accessed directly.
