ON-BOARD DIAGNOSTIC [FORWARD SENSING CAMERA (FSC)]

id1502006955a3


Outline

•  The on-board diagnostic function consists of the following functions:
―  A malfunction detection function, which detects overall malfunctions in the forward sensing camera (FSC)-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.

Malfunction detection function

•  Detects malfunctions in input/output signals.
•  If a malfunction occurs, the forward sensing camera (FSC) records the malfunction as a DTC. A recorded DTC can be read by the Mazda Modular Diagnostic System (M-MDS).

Drive cycle

•  The drive cycle is the period of time from when the engine is started to the next time the engine is started.
•  One drive cycle, as shown in the figure, indicates the period from the time engine is started to the next time the engine is started. If this period is repeated twice it then becomes two drive cycles.
am6zzn00006065
•  To detect DTCs, a required number of drive cycles for pre-detection has been set. For the number of drive cycles required for detection, refer to the 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.
am3zzn00005432


Status byte for DTC

•  The two digits (two digits after hyphen (-)) after the 7-digit DTC.
am3zzn00005433
•  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.
