AUTO LIGHT SYSTEM

System Diagram






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 and headlamps according to CAN communication signals from BCM.
- Optical sensor detects ambient brightness and converts light (lux) to voltage, 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 and headlamps in accordance with the ambient light. Sensitivity can be adjusted in four steps. For the details of the setting, Refer to EXL-20, "EXTERNAL LAMP: CONSULT-III Function". External Lamp: CONSULT-III Function

Component Description

AUTO LIGHT OPERATION
The auto light system operates the low beam and high beam headlamps, parking lamps, tail lamps and license plate lamps. The BCM monitors the lighting switch (combination switch) position as a part of the BCM combination switch reading function. When the lighting switch is in the AUTO position, the BCM automatically turns the lamps ON/OFF according to ambient light brightness.

NOTE: Timing for when lamps turn ON/OFF can be changed by the function setting of CONSULT-III. Refer to "EXTERNAL LAMP: CONSULT-III Function". External Lamp: CONSULT-III Function
