On-Board Diagnostic; Outline - Mazda 6 Training Manual

OUTLINE

• The operation of the on-board diagnostic system for ABS (ABS/TCS) or DSC is essentially carried over from
that of the previous 323 (BJ) model ecept for the following. (See Mazda 323 Workshop Manual Supplement
1704-1*-99H.)
— Changed of DTC code, PID data monitor function, and active command function
— Eliminated TBS terminal of DLC
• Using the WDS or equivalent with the ABS (ABS/TCS) or DSC HU/CM, allows for a 4-digit DTC display
function, a PID/DATA monitor function, and an active command modes function, and thus improves
serviceability.
