  2. CHECK PUSH-BUTTON START FUNCTION


    1. Check the push-button start function:


      1. Get into the vehicle while carrying the electrical key transmitter sub-assembly with the power switch off. With the shift lever in P, check that the smart warning light is displayed when the brake pedal is depressed. Then check that the hybrid control system starts when the power switch is pressed after the smart warning light is displayed.

      2. While the brake pedal is released and the electrical key transmitter sub-assembly is being carried, check that the power source mode changes in the following order when the power switch is pressed: off → on (ACC) → on (IG) → off.

        Tech Tips

        When the power switch is pressed with the power switch on (IG) and the shift lever not in P, the power source mode does not change to off, but changes to on (ACC).

      3. With the shift lever in P, check that the steering lock operates when a door is opened.

        Tech Tips

        When the power switch is pressed after the vehicle is stopped, the hybrid control system stops and all the power turns off. However, if the shift lever is not in P when the power switch is pressed with the vehicle stopped, the power source mode does not change to off, but changes to on (ACC).
