ON-BOARD DIAGNOSTIC SYSTEM [ELECTRIC POWER STEERING (EPS)]

• 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.

• 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 PID/data monitor, providing enhanced malfunction diagnosis and improved serviceability.

*1 :C: CMDTC self test, D: ODDTC self test

*2 :If the EPS CM detects an internal circuit malfunction in the resolver sensor, it flashes the power steering malfunction indicator light. At this time, if EPS system internal temperature increases, the assist force gradually weakens. Then if assist force decreases above the specified value, the power steering malfunction indicator light switches from flashing to illumination.

*3 :If the EPS CM detects the signal that a engine speed is below the specified value, it illuminates the power steering malfunction indicator light.
