ON-BOARD DIAGNOSTIC FUNCTIONA6E811155430205Outline
•The on-board diagnostic function is incorporated into the PCM, TCM, ABS (ABS/TCS) HU/CM (with ABS (ABS/
TCS)), DSC HU/CM (with DSC), 4WD control module, and instrument cluster. This function can narrow down
CAN system malfunction locations.
•Due to the adoption of the TCM and the 4WD CM, some DTCs and PID/data monitor items have been added.
Other functions are the same as those of the current Mazda6 (GG) model.
Block Diagram
.
Fail-Safe Function
•When the failure detection function detemines that there is a malfunction, the fail-safe function illuminates a
warning light to advise the driver of the malfunction.

Self-Malfunction Diagnostic Function
•The self-malfunction diagnostic function determines that there is a malfunction, and outputs a signal, as a DTC,
to the DLC-2. The DTC can be read out using an SST (WDS or equivalent).
DTC table
PID/Data Monitoring Function
•The PID/data monitoring function is used to freely select and read out, in real time, the monitored items for the
input/output signals of the TCM, ABS (ABS/TCS) HU/CM, DSC HU/CM and instrument cluster.
•An SST (WDS or equivalent) is used to read out the PID/data monitor information.
