ON-BOARD DIAGNOSTIC [MAZDA ERA-GLONASS CONTROL MODULE]


id092200021860


Outline

•  The on-board diagnostic function consists of the following functions:
―  A malfunction detection function, which detects overall malfunctions in the MAZDA ERA-GLONASS system-related parts.
―  A memory function, which stores detected DTCs.
―  A display function, which indicates malfunction locations and status via DTC output.
•  Using the Mazda Modular Diagnostic System (M-MDS), DTCs can be read out and deleted.

Malfunction detection function

•  Detects malfunctions in input/output signals.
•  If a malfunction occurs, the MAZDA ERA-GLONASS control module records the malfunction as a DTC. A recorded DTC can be read by the Mazda Modular Diagnostic System (M-MDS).

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 store data using scanning tool when necessary. The DTCs are indicated using seven digits. Each digit indicates the following.
am3zzn00005438


Status byte for DTC

•  The two digits (two digits after hyphen (-)) after the 7-digit DTC.
am3zzn00005439
•  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 MAZDA ERA-GLONASS control module stores the following two types of snapshot data (vehicle information) when a DTC is detected and displays them in the Mazda Modular Diagnostic System (M-MDS).
―  Vehicle information detected by MAZDA ERA-GLONASS control module
―  Vehicle information detected by instrument cluster and received by MAZDA ERA-GLONASS control module via CAN communication
•  The data for all DTCs currently detected is stored.
