Principles of Operation
PRINCIPLES OF OPERATIONThe SJB communicates via the medium speed controller area network (MS-CAN).
The SJB controls the power door lock system. The module monitors the door lock/unlock switch inputs from the interior door lock switches. When the module receives an unlock/lock command from any door lock control switch, the module activates the door lock actuators. Refer to Locks.
The module also controls the following remote lock/unlock features:
- Remote keyless entry (RKE) transmitter lock/unlock (buttons are part of the integrated keyhead transmitter [IKT] key)
- Panic alarm (button is part of the IKT key)
- Keyless entry keypad
The SJB controls the autolamp subsystem. The autolamp subsystem provides light-sensitive automatic on/off control of the headlamps and parking lamps. Refer to Lighting and Horns.
