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 power switch on (IG), the vehicle is normal.

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


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

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


      Powertrain > Hybrid Control > Data List

      Atmosphere Pressure

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

      A01MRXN

      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). This varies by weather.

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