CAUTION / NOTICE / HINT

Tech Tips

After the repair, perform the following procedure to confirm the repair.


  • If the values of Data List items "Atmosphere Pressure" and "MAP" are almost the same with the engine stopped and the power switch on (IG), those sensors are normal.

  • If the values of Data List items "Atmosphere Pressure" and "MAP" are still difference 10 kPa or more after after replacing components of the inverter with converter assembly, replace the inverter with converter assembly.
