INSTRUMENT CLUSTER ON-BOARD DIAGNOSTIC OPERATION

id092200468500


Malfunction Detection Function

•  If a malfunction occurs in the input/output signals, other units, or the CAN system, it is recorded as a DTC. Recorded DTCs 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.
