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 "*1" 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 No. P1272 and P1273 are stored.
note *2: When the diagnosis codes relating to the CAN communication error are output, make sure of the vehicle equipment. When the vehicle is not equipped with the system the engine-ECU communicates to, the diagnosis code is always output. This is not abnormal.

note *1: The PTC heater relay 2 is the circuit that is turned to ON when the PTC heater relay 1 is turned to ON. The operations of the PTC heater relay 2 can be checked by the item No. 76 PTC heater relay 1. The data item, PTC heater relay 2, is shown on the M.U.T.-III display, but "OFF" is always shown.
note *2: The data item, Exhaust absolute pressure sensor is shown on the M.U.T.-III display although the exhaust absolute pressure sensor is not used. Thus, the item, Exhaust absolute pressure sensor, is not used for the check.

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.
