• The OBD system has the following functions:

  - Failure detection function: detects failure of input/output devices and system components of the ATX.
  - Fail-safe function: fixes the output device function and input value of the sensors/switches to ensure minimum vehicle drivability when a failure is detected.
  - Memory function: stores the DTC when a failure is detected.
  - PID data monitoring function: monitors the input/output signal and calculated value of the PCM and sends the monitoring data to the WDS or equivalent.
  - Simulation function: Allows override operation of simulation items for input/output system parts preset in the PCM.
