DPE050200000T01

• The OBD system has the following functions:

— 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 drivability when a malfunction is detected.

— Memory function: stores the DTC when a malfunction 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.
