DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Select “Data Monitor” mode for “TRANSMISSION”.
3. Start engine.
4. Drive vehicle and maintain the following conditions for at least 2 consecutive seconds.
With GST
Follow the procedure “With CONSULT-III”.
