• The on-board diagnostic system consists of a malfunction detection system that detects abnormalities in input/
output signals when the ignition switch is at the ON position, a data monitor function that reads out specified
input/output signals, and an active command modes function that execuse the wheel unit ID registration.
• The Data Link Connector 2 (DLC-2), which groups together all the connectors used for malfunction diagnosis
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 data monitor, providing enhanced malfunction
diagnosis and improved serviceability.
