ON-BOARD DIAGNOSTIC FUNCTION
id094000101700
•
The on-board diagnostic system consists of a malfunction detection system that detects abnormalities in input/
output signals, a data monitor function that reads out specified 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, and to access the PID/data monitor function, providing enhanced
malfunction diagnosis and improved serviceability.
Malfunction Detection Function
•
The malfunction detection function detects malfunctions in the input/output signal system of the BCM.
