Tribute 2WD V6-3.0L (2008)
Power Distribution Module: Description and Operation
Smart Junction Box (SJB)
SMART JUNCTION BOX (SJB)
Principles of Operation
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). For additional
information on the battery saver relay, see INTERIOR LIGHTING. For additional information on the accessory delay relay, see GLASS, FRAMES
AND MECHANISMS. 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.
The SJB is a multi-function control module that controls many of the vehicle systems. Several SJB functions utilize hardwired inputs and/or outputs. The
SJB controls the following hardwired functions, using the corresponding inputs and outputs:
In addition, the SJB is involved in other vehicle systems through communication over the controller area network (CAN). For a detailed list of SJB
network inputs and outputs, see MODULE CONFIGURATION. See: Body and Frame/Body Control Systems/Testing and Inspection/Programming and
Relearning
Some SJB parameters are programmable. Two types of programmable parameters are available: vehicle configuration and customer preference. See
MODULE CONFIGURATION See: Body and Frame/Body Control Systems/Testing and Inspection/Programming and Relearning for additional
information on programmable parameters.
The SJB utilizes a protective circuit strategy for many of its outputs (for example, the headlamp output circuit). Output loads (current level) are
