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



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


    A250945

  1. 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

  1. Turn the power switch off.

4.READ VALUE USING INTELLIGENT TESTER (MAP)

  1. Push the P position switch.

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

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

  1. While depressing the brake pedal, turn the power switch on (READY).

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

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

  1. 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).

  1. Turn the power switch off.
