CAUTION / NOTICE / HINT

Tech Tips

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


  1. If the values of Data List items "Atmosphere Pressure" and "MAP" are almost the same with the engine stopped and the ignition switch to ON (IG), the vehicle is normal.

  3. READ VALUE USING GTS (MAP, ATMOSPHERE PRESSURE)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Data List / MAP, Atmosphere Pressure.

    4. Using the table, read the normal atmospheric pressure value for the applicable altitude.

      A004FSJ

      Tech Tips


      • Standard atmospheric pressure is approximately 101 kPa.

      • For every 100 m (328 ft) increase in altitude, atmospheric pressure drops by approximately 1 kPa (7.5 mmHg).

      • The actual atmospheric pressure also varies by weather.

    5. Compare the MAP and Atmosphere Pressure values in the Data List with the normal atmospheric value from the table.

      Result
      Result Proceed to
      Other than the following. A
      Difference between MAP in Data List and "normal atmospheric pressure value" is 10 kPa or more. B
      Difference between Atmosphere Pressure in Data List and "normal atmospheric pressure value" is 10 kPa or more. C

    6. Turn the ignition switch off.

  4. READ VALUE USING GTS (MAP)


    1. Move the shift lever to P.

    2. Enter the following menus: Powertrain / Hybrid Control / Data List / MAP

    3. Read the MAP value in the Data List with the engine stopped.

    4. While depressing the brake pedal, Turn the ignition switch to ON (READY).

    5. With the READY indicator light illuminated, fully depress the accelerator pedal.

    6. Read the MAP value in the Data List with the engine running.

    7. Compare the MAP value noted with the engine stopped and the MAP value noted with the engine running.

      OK
      The MAP value changes (pressure decreases when the engine is started).

    8. Turn the ignition switch off.
