• The OBD system has the following functions:

- Failure detection function: detects failure of the input/output devices and system components of the ATX.

- Memory function: stores the DTC when a failure is detected.

- 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.

- PID data monitoring function: monitors the input/output signal and calculated value of the TCM and sends the monitoring data to the scan tool.
