ON-BOARD DIAGNOSTIC SYSTEM OUTLINE [DYNAMIC STABILITY CONTROL (DSC)]
NG: DYNAMIC STABILITY CONTROL
! The on-board diagnostic system consists of a malfunction detection system that detects malfunctions in input/
output signals when the ignition is switched to ON, a PID/data monitor function that reads out specified input/
output signals, and a active command modes function that allows for override operation of output parts (such
as solenoid valves).
! 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 and active command modes
functions, providing enhanced malfunction diagnosis and improved serviceability.
