- After the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates, it will be switched off under the following conditions.

- When the ECM or PCM monitored the power train malfunction three times* and met set condition requirements, it detected no malfunction. *: In this case, "Done time" indicates from engine start to stop.
