NOTE: The smart junction box (SJB) is also known as the generic electronic module (GEM).
NOTICE: Electronic modules are sensitive to static electrical charges. If exposed to these charges, damage may result.
The SJB controls the power door lock system.
The SJB monitors the door lock/unlock switch inputs from the interior door lock switches.
When the SJB receives an unlock/lock command from any door lock control switch, the module activates the door lock actuators.
The SJB also controls the following remote lock/unlock features:
Remote keyless entry (RKE) transmitter lock/unlock
Panic alarm (button is part of the RKE transmitter)
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 SJB controls the battery saver, delayed accessory function, exterior and interior lighting and the horn.
The SJB controls the tire pressure monitoring system (TPMS) for the late build vehicles only.
Early build vehicles do not have this feature
