  4. READ VALUE USING INTELLIGENT TESTER (MAP)


    1. Push the P position switch.

    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 power switch on (READY).

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