Principles of Operation
PRINCIPLES OF OPERATIONWhen the headlamp switch is placed in the autolamp position, the smart junction box (SJB) monitors the light sensor. The light sensor detects the ambient light level, and in turn, the SJB determines whether to turn the exterior lamps on or off.
The autolamp feature also delays turning off the exterior lamps after the ignition switch is placed in the OFF or ACC position. The delay period for turning off the exterior lamps is 20 seconds.
