Malfunction detection function

DTC table

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.
