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

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.
