AFS (ADAPTABLE FRONT LIGHTING SYSTEM) CONTROL MODULE FUNCTION

id091800691100

―  Light-bending lamp function

―  Auto headlight leveling function

―  On-board diagnostic system (fail-safe function)

―  Controls the light-bending illumination integrated in the headlights based on the vehicle speed and steering angle sensor signals while the vehicle is being driven.

―  Calculates the target optical axis against changes in the vehicle attitude determined by the front and rear auto leveling sensors.

―  Controls the headlight leveling actuator relative to the target optical axis according to the driving conditions determined by the rate of vehicle speed and acceleration.

―  Malfunction Detection Function

•  Detects overall malfunctions in the AFS-related parts. If the AFS (adaptive front lighting system) has a malfunction, the AFS OFF light flashes in the following pattern and a DTC is output.

DTC			Description
AFS OFF light flashing pattern		Mazda Modular Diagnostic System (M-MDS) display (instrument cluster)
1		U0483:68	AFS control module communication system
2		U0483:92	Auto leveling sensor signal
3		—	AFS control module initial setting

―  Fail-safe Function

•  If the adaptive front lighting system performance/function cannot be maintained for some reason, the system control is stopped or the system operation is restricted to a level which does not cause a loss in vehicle operability. At this time, the AFS OFF light flashes.

―  AFS (Adaptive front lighting system) operational inspection function

•  Perform the specified procedure and the AFS (Adaptive front lighting system) self-diagnosis. If the system operates normally, headlight-bending turns on. For the AFS (Adaptive front lighting system) operational inspection, refer to the workshop manual.
