- Malfunction detection function: Detects malfunctions of the 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 driveability when a malfunction is detected.

- Memory function: Stores the DTC when a malfunction is detected.

- PID data monitored 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.
