note
  • 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 "*" in the diagnosis code number column, the engine warning lamp illuminates only on the first detection of the malfunction.
  • When the fuel runs out, the engine warning lamp would illuminate possibly. Supplying the fuel turns off the engine warning lamp, but the diagnosis code Nos. P1272 and P1273 are stored.

Engine-ECU Monitor Item



  • Items useful for grasping the engine control condition by the engine-ECU are provided in this monitor item section.
  • Values of these monitor items vary greatly depending on marginal difference of measurement conditions, difference of the environment, aged deterioration of vehicles and so on, and it is difficult to show the precise specification values. Therefore, check conditions, display range and movement of values are described.
