NOTE:
1. Do not replace the engine control module (ECM) until a thorough terminal check reveals there are no short/open circuits.
2. After the ECM detects a malfunction, a diagnostic trouble code is recorded when the engine is next started and the same malfunction is re-detected.
Items marked with a "*", the diagnostic trouble code is recorded on the first detection of the malfunction.
3. 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.
4. O2 : Heated oxygen sensor
5. Sensor 1 : indicates sensors which are mounted closest to the engine.
6. Sensor 2 : indicates sensors which are mounted next-closest to the engine.




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