ON-BOARD DIAGNOSIS SYSTEM [REAR ONE-TOUCH WALK-IN CONTROL MODULE]

id091300408700

Outline

Function

•  The on-board diagnostic function consists of the following functions:

―  A malfunction detection function, which detects overall malfunctions in the rear one-touch walk-in control module-related parts.

―  A memory function, which stores detected DTCs.

―  A display function, which indicates malfunction locations and status via DTC output.

―  A PID/data monitor 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 monitor function can be activated.

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.

am6zzn00002847

Status byte for DTC

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

am6zzn00002848

•  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.
