System Description

  • BCM (Body Control Module) controls auto light operation according to signals from optical sensor, lighting switch and ignition switch.
  • IPDM E/R (Intelligent Power Distribution Module Engine Room) operates parking, license plate, tail, front fog lamps and headlamps according to CAN communication signals from BCM.
  • Optical sensor detects ambient brightness of 800 to 2,500 lux, converts light (lux) to voltage, and then sends the optical sensor signal to BCM.

OUTLINE

The auto light control system has an optical sensor that detects outside brightness.

When the lighting switch is in AUTO position, it automatically turns ON/OFF the parking, license plate, tail, front fog lamps and headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps.
