PRINCIPLES OF OPERATION

NOTE:
- The smart junction box (SJB) is also known as the generic electronic module (GEM).
- The time out for the battery saver relay and the accessory delay relay (both are controlled by the SJB) 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. Refer to Lighting and Horns for information on the battery saver relay. Refer to Windows for information on the accessory delay relay.

The 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
- 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. Refer to Switches.
