ON-BOARD DIAGNOSTIC FUNCTION [AFS (ADAPTIVE FRONT LIGHTING SYSTEM) CONTROL MODULE]

id091800693000


Malfunction Detection Function

•  The AFS has an on-board diagnostic function to facilitate system diagnosis.
•  The on-board diagnostic function consists of the following functions: a malfunction detection function, which detects overall malfunctions in the AFS-related parts; a memory function, which stores detected DTCs; a display function, which indicates system malfunctions via DTC display; and a PID/data monitoring function, which reads out specific input/output signals.
•  Using the Mazda Modular Diagnostic System (M-MDS), DTC read-out can be performed. Also, some DTCs can be read out based on the AFS OFF light flashing pattern
•  Detected DTCs are recorded in the AFS control module.
•  After vehicle repair, the recorded DTCs can be cleared using the Mazda Modular Diagnostic System (M-MDS).
•  Refer to the Workshop Manual for DTC read-out and clearing procedures.

AFS OFF light flashing pattern

•  If the AFS has a malfunction, the AFS OFF light flashes in the following pattern and a DTC is output.

DTC 7-digit code definition

•  When related systems or components have failed, the CM stores the DTC of the malfunctioning part in the CM memory, and allows for the retrieval of the store data using scanning tool when necessary. The DTCs are indicated using seven digits. Each digit indicates the following.
