Principles of Operation
PRINCIPLES OF OPERATIONThe SJB is a multifunction module that controls many of the vehicle systems. Most of the SJB functions utilize hardwired inputs and/or outputs. The SJB controls the hardwired functions, using the corresponding inputs and outputs:
In addition, the SJB is involved in other vehicle systems through communication over the medium speed controller area network (MS-CAN). For a detailed list of SJB network inputs and outputs, refer to Information Bus (Module Communications Network), Principles of Operation.
Some SJB parameters are programmable. Two types of programmable parameters are available: vehicle configuration and customer preference.
