ON-BOARD DIAGNOSTIC (OBD) SYSTEM OUTLINE [AW6A-EL, AW6AX-EL] NG: AUTOMATIC TRANSAXLE
• 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: controls 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 TCM and sends
the monitoring data to the scan tool.
- Simulation function: Allows override operation of simulation items for input/output system parts preset in the
TCM.
