Principles of Operation
PRINCIPLES OF OPERATIONThe smart junction box (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.
The module also controls the following remote lock/unlock features:
- Remote keyless entry (RKE) transmitter lock/unlock
- Panic alarm
- 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.
The third row power-fold seat relays are also controlled by the SJB. This allows the seats to be adjusted by pressing one of the third row power-fold seat switches.
