NOTES:
1. After the Engine Control Module (ECM) detects a malfunction, the check engine/malfunction indicator lamp illuminates when the engine is next turned on and the same malfunction is re-detected. However, for items marked with an asterisk, the check engine/malfunction indicator lamp illuminates on the first detection of the malfunction.

2. After the check engine/malfunction indicator lamp illuminates, it will be switched off under the following conditions.
- When the ECM monitored the powertrain malfunction three times* and detected no malfunction. *: In this case, one time indicates from engine start to stop.
- For misfiring or a fuel trim malfunction, when driving conditions (engine speed, engine coolant temperature, etc.) are similar to those when the malfunction was first recorded.

CAUTION: If the check engine malfunction indicator lamp illuminates because of a malfunction of the ECM, transmission between the scan tool and the ECM cannot occur. In this case, the diagnostic trouble code cannot be read.
