 DTC CONFIRMATION PROCEDURE
 1.PREPARATION BEFORE OPERATION
If another “DTC CONFIRMATION PROCEDURE” is performed just before the next test, turn the ignition switch OFF and wait for 10 seconds or more, then perform the next test. >>GO TO 2.
 2.PERFORM DTC CONFIRMATION PROCEDURE — DTC DETECTION CONDITION A
 With CONSULT-III - Turn the ignition switch ON.
- Shift the shift lever to N the position.
- Start the engine.
- Select “RANGE” and “GEAR” in “Data Monitor”.
- With the vehicle stationary, maintain the following conditions for 5 seconds or more.
- Check “Self Diagnostic Result” of “TRANSMISSION”.
 Without CONSULT-III - Turn the ignition switch ON.
- Shift the shift lever to N the position.
- Start the engine.
- With the vehicle stationary, maintain the following conditions for 5 seconds or more.
Shift lever
| : M range
| Gear
