ON-BOARD DIAGNOSTIC [STANDARD DEPLOYMENT CONTROL SYSTEM]

Outline

  • 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 malfunction locations and status via DTC output.

    • A PID/data monitoring function, which reads out specific input/output signals and verifies the input/output condition.

  • Using the Mazda Modular Diagnostic System (M-MDS), DTCs can be read out and deleted, and the PID/data monitoring function can be activated.

Function

Self-diagnostic function
    Memory function

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

    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.

    DTC 7-digit code definition

  • When related systems or components have failed, the CM stores the DTC of the malfunctioning part in the CM memory, and allows for the retrieval of the stored data using the scanning tool when necessary. The DTCs are indicated using seven digits. Each digit indicates the following.

    Status byte for DTC

  • The two digits (after hyphen) after the 7-digit DTC.

  • A code which indicates the pending code, current/past malfunction status, or warning illumination status.

  • Can be read by performing a CMDTC self-test using the Mazda Modular Diagnostic System (M-MDS).

  • For details on the status byte, refer to the explanation on the Mazda Modular Diagnostic System (M-MDS) when reading the DTC.

Snapshot data

NOTE:

  • The SAS control module stores the following two types of information when a DTC is detected and displays snap shot data in the Mazda Modular Diagnostic System (M-MDS).

    • Vehicle information detected by SAS control module

    • Vehicle information detected by instrument cluster and received by SAS control module via CAN signal

  • The data for all DTCs currently detected is stored.

TOTAL_DIST

km

Accumulated total traveled distance from completion of vehicle until SAS control module detects DTC (Odometer value in instrument cluster)

The total traveled distance from which the SAS control module detects DTCs to the present can be calculated by performing the following procedure.

  • Verify the odometer value in the instrument cluster.

  • Verify the snapshot data item TOTAL_DIST.

  • Subtract 2 from 1.

TOTAL_TIME

ss*1

Accumulated total elapsed time since vehicle completion until SAS control module detects a DTC*3

NOTE:

  • When the ROOM fuse is removed, and the ignition is switched off, the time is not included in the elapsed time.

The elapsed time from which the SAS control module detects DTCs to the present can be calculated by performing the following procedure.

  • Verify the instrument cluster PID item TOTAL_TIME.

  • Verify the snapshot data item TOTAL_TIME.

  • Subtract 2 from 1.
