Items Indicated by the Service Engine Soon/Malfunction Indicator Lamp
NOTE:
1. After the Engine Control Module (ECM) detects a malfunction, the Service Engine Soon/malfunction indicator lamp illuminates when the engine
is next turned on and the same malfunction is re-detected. However, for items marked with a"*", the Service Engine Soon/Malfunction Indicator
Lamp illuminates on the first detection of the malfunction.
2. After the Service Engine Soon/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 Service Engine Soon/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.
