Toyota CH-R Service Manual: System Description

SYSTEM DESCRIPTION

AUTOMATIC HEADLIGHT BEAM LEVEL CONTROL

(a) General

The automatic headlight beam level control system ensures forward visibility and prevents dazzling of drivers in oncoming and preceding vehicles by controlling the headlight beam level vertically when the weight of passengers and loads has caused the vehicle attitude to change.

(b) Function of Main Components

Component

Outline

Headlight ECU Sub-assembly

Receives various signals, calculates changes in the vehicle posture, and actuates the headlight leveling motor.

Headlight Unit Assembly (Headlight Leveling Motor)

Based on the signals received from the headlight ECU sub-assembly LH or RH, the motors move the reflectors in the headlight to change the low beam angle.

Rear Height Control Sensor Sub-assembly LH

Transmits a height control sensor signal to the headlight ECU sub-assembly LH.

Brake Actuator Assembly (Skid Control ECU)

Transmits a speed sensor signal to the headlight ECU sub-assembly LH.

ECM

Transmits an engine running status signal to the headlight ECU sub-assembly LH.

Main Body ECU (Multiplex Network Body ECU)

Transmits a headlight status signal to the headlight ECU sub-assembly LH.

Combination Meter Assembly

If the system malfunctions, "Headlight System Malfunction Visit Your Dealer" warning message will be displayed on the multi-information display in the combination meter assembly in accordance with the signal from the headlight ECU sub-assembly LH.

(c) Initial Set Control

When the engine is started, the headlight ECU sub-assembly LH drives the headlight leveling motor and moves the headlight reflector to the lower limit position and returns it to the proper position. The headlight ECU sub-assembly LH thus assesses the position of the headlight for reference control.
