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


id091800693000

•  The on-board diagnostic system consists of a malfunction detection system that detects abnormalities in input/output signals.
•  The data link connector 2 (DLC-2), which groups together all the connectors used for malfunction diagnosis and detecting/repair into a single location, has been adopted, thereby improving serviceability. Diagnosis is performed by connecting the Mazda Modular Diagnostic System (M-MDS) to the DLC-2.
•  In addition to DTC read-out, the Mazda Modular Diagnostic System (M-MDS) is used to clear DTCs using the display screen of the diagnostic tester, providing enhanced malfunction diagnosis and improved serviceability.

Malfunction Detection Function

•  The malfunction detection function detects malfunctions in the input/output signal system of the AFS control module.

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.
