Component Parts Description


AFS CONTROL UNIT
AFS control unit determines current vehicle conditions by received signals and controls AFS and headlamp auto aiming.

SWIVEL ACTUATOR





Swivel actuator is configured with swivel motor and swivel position sensor and is built in headlamps.





- Swivel motor (step motor)
Swivel motor is a two-phase step motor. It is driven according to drive signals from AFS control unit when two drive windings are energized in set sequences, and adjusts low beam projector of headlamp.
The direction of actuator rotation can be changed as desired by selecting appropriate energizing sequences.
- Swivel position sensor
Swivel position sensor detects swivel angle and transmits a swivel position sensor signal to the AFS control unit.

AIMING MOTOR





Aiming motor is installed outside the headlamps. Headlamp aiming motors set the low beam projectors according to headlamp aiming motor drive signals received from AFS control unit.

AFS SWITCH





AFS switch transmits state of ON/OFF as AFS switch signals to AFS control unit.
- AFS control unit performs AFS operation when AFS switch is ON and turns off AFS off indicator lamp.
- AFS control unit does not perform AFS operation when AFS switch is OFF, and turns on AFS off indicator lamp.

HEIGHT SENSOR





The height sensor is located on the left side of the rear suspension member and detects rear vehicle height change by sensing the displacement of the rear suspension arm. And transmits a height sensor signal to the AFS control unit.






STEERING ANGLE SENSOR





The steering angle sensor is located combination switch and detects steering angle. And transmits a steering angle sensor signal to the
AFS control unit.

IPDM E/R
IPDM E/R detects ON/OFF state of low beam headlamps. It transmits a low beam state signal to the AFS control unit.

ECM
ECM transmits an engine speed signal to the AFS control unit.

TCM
TCM transmits an A/T position indicator signal to the AFS control unit.

UNIFIED METER AND A/C AMP.
- Unified meter and A/C amp. transmits vehicle speed signals to the AFS control unit.
- Unified meter and A/C amp. transmits AFS off indicator signals received from the AFS control unit to the combination meter.

COMBINATION METER
Combination meter turns on/off or blinks built-in AFS off indicator lamp depending on AFS off indicator signal received from unified meter and A/C amp.
