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

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; and 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 FSC 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.

Status byte for DTC

The status byte is the two digits (two digits after hyphen (-)) after the 7-digit DTC.

The status byte is a code which indicates the pending code, current/past malfunction status, or warning illumination status.

The status byte 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.
