Smart Junction Box (SJB)

NOTE: The 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 passes the approximate mileage threshold of 80 km (50 miles), the time out for both relays will be the normal 10 minute time out, as described by the Owner's Literature. For the battery saver relay, refer to Lighting and Horns. For the accessory delay relay, refer to Windows.

The SJB is a combination of a multifunction electronic module and an interior fuse panel. SJB functions control multiple vehicle systems, which include:
- Battery saver relay
- Brake shift interlock

- Global open (front windows only)
- Heated rear window
