Engine-ECU monitoring items



  • This monitor item includes many useful items for understanding the engine conditions controlled by the engine-ECU.
  • However, it is hard to show the definite specification of each item, since its value may vary to a large extent with a little difference in the measuring conditions, environment, and changes with the lapse of time, etc. on the objective vehicle.Therefore, this document will describe only the check conditions, display range, and behavior of numeric values.
