ON-BOARD DIAGNOSTIC SYSTEM FUNCTION

id080200300300


Self-diagnostic Function


Malfunction detection function

•  Detects overall malfunctions in the air bag system-related parts.


Fail-safe function

•  If the SAS control module performance/function cannot be maintained due to any cause, the fail-safe function stops air bag system control and flashes the air bag system warning light to prevent the air bags from operating (deploying) accidentally.


Memory function

•  Stores malfunctions in the air bag system-related parts detected by the malfunction detection function, and the stored malfunction contents are not cleared even if the switch the ignition to off or the negative battery cable is disconnection.


Display function

•  When the malfunction detection function detects a malfunction, the air bag system warning light illuminates to advise the driver. Using the external tester communication function, DTCs can be output to the DLC-2 via the CAN.

PID/Data Monitoring Function

•  By using the PID/data monitoring function, the monitored item of the input/output signal, as set on the SAS control module, can be freely selected and read out in real-time.
•  The Mazda Modular Diagnostic System (M-MDS) is used to read out PID/data monitor information.
