NOTE
1. If the engine warning lamp illuminates because of a malfunction of the engine-ECU (engine-A/T-ECU),
communication between MUT-II and the engine-ECU (engine-A/T-ECU) is impossible. In this case,
the diagnosis code cannot be read.
2. After the engine-ECU (engine-A/T-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.
As for P1220, P1221, P1223, P1224, and P1228, the engine warning lamp flashes. If malfunctions
are detected at the throttle position sensor (1st channel) and the throttle position sensor (2nd channel)
at the same time, or malfunctions are detected at the accelerator pedal position sensor (1st channel)
and the accelerator pedal position sensor (2nd channel) at the same time, the engine warning lamp
will flash.
3. After the engine warning lamp illuminates, it will be switched off under the following conditions.
(1) When the engine-ECU (engine-A/T-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.
