NOTE
1. If the engine warning lamp illuminates because of a malfunction of the engine-ECU, communication
between MUT-II and the engine-ECU is impossible. In this case, the diagnosis code cannot be read.
2. After the engine-ECU has detected a malfunction, the engine warning lamp illuminates when the
engine is next turned on and the same malfunction is re-detected. However, for items marked with
a "L" in the diagnosis code number column, the engine warning lamp illuminates only on the first
detection of the malfunction.
3. After the engine warning lamp illuminates, it will be switched off under the following conditions.
(1) When the engine-ECU monitored the power train malfunction three times* and met set condition
requirements, it detected no malfunction.
*: In this case, "one time" indicates from engine start to stop.
(2) For misfiring malfunction, when driving conditions (engine speed, engine coolant temperature,
etc.) are similar to those when the malfunction was first recorded.
4. Sensor 1 indicates the sensor mounted at a position closest to the engine, and sensor 2 indicates
the sensor mounted at the position second closest to the engine.
