  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.

      A250945
      Tip:

      • Standard atmospheric pressure is approximately 101 kPa (15 psi).

      • For every 100 m (328 ft.) increase in altitude, atmospheric pressure drops by approximately 1 kPa (0.1 psi). This varies by weather.

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