• The air bag system has an on-board diagnostic function to facilitate the system diagnosis.
• The on-board diagnostic function consists of the following functions: a malfunction detection function, which detects overall malfunctions in the air bag system-related parts; a memory function, which stores detected DTCs; a display function, which indicates system malfunctions by DTC display; a PID/data monitoring function, which reads out specific input/output signals.
• Using the Mazda Modular Diagnostic System (M-MDS), DTCs can be read out and deleted, and the PID/data monitoring function can be activated.
• The system has a fail-safe function to prevent the accidental activation of the air bags in case of an air bag system malfunction.
