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.

INTRUDER SENSORA6E812050000202Outline
•WGN models are equipped with intruder sensors in two places in the vehicle, due to the necessity of movement
detection in the all around wider vehicle interior. The intruder sensors are located in the roof at the front (with
sliding sunroof), or the center (without sliding sunroof), and the cargo space.
•The structure and operation of the rear intruder sensor is the same as that of the current front and center
intruder sensors.
