6.1.14. Onboard diagnostics
Work of system of onboard diagnostics of anti-blocking system of brakes (ABS/TCS) or DSC is in essence borrowed from the previous model 323 (BJ), except for the following:
– diagnostic codes, functions of the monitor of data of PID and function of active teams are changed;
– a conclusion of the TBS DLC socket is removed;
Fig. 6.8. Flowchart of system of onboard diagnostics of the Mazda 3 car: 1 – control lamp of the TCS (DSC) system; 2 – control lamp of shutdown of the TCS (DSC) system; 3 – lamp of the alarm system of anti-blocking system of brakes; 4 – lamp of the alarm system of the brake system; 5 – malfunction display function; 6 – function of onboard diagnostics; 7 – consecutive communication; 8 – memory function; 9 – failure detection function; 10 – function of control of data; 11 – function of active team; 12 – reliability function; 13 – input equipment of data; 14 – normal field of management; 15 – DLC 2 socket; 16 – WDS or analog; 17 – function of check of hydraulic elements; 18 – output device
– use of WDS or an analog with anti-blocking system of brakes (ABS/TCS) or DSC HU/CM allows to provide four-digit display of diagnostic codes and active purpose of the command modes that improves maintainability.
