ASC SYSTEM OPERATION CHECK


  1. INSPECT ASC SYSTEM OPERATION

    CAUTION:

    Check for safety before performing any tests.

    Tech Tips

    If the drive mode is changed to a mode other than SPORT S+ or CUSTOM* while the ASC system is operating, the dynamic engine sounds will stop.

    *: Additional engine sounds are generated when CUSTOM mode is set to Power on the Drive Mode Customization or Drive Mode Customisation screen of the multi-display.

    1. Check additional engine sounds generation


      1. Start the engine.

      2. Select SPORT S+ mode.

      3. Move the shift lever to D or M. When the vehicle speed is 6 km/h (4 mph) or more and the engine speed is 980 rpm or more, check that additional engine sounds are generated in accordance with the engine speed.

        Tech Tips

        Check the difference in sound when the mode is changed between ECO (not generated), NORMAL (not generated), SPORT S (not generated) and SPORT S+ (generated).

    2. Check additional engine sounds generation (CUSTOM mode)


      1. Start the engine.

      2. Check that CUSTOM mode has been set to Power on the Drive Mode Customization or Drive Mode Customisation screen of the multi-display.

        [Setup] → [Vehicle] → [Drive mode customization] → [Powertrain] → [Power] (Type A)

        [Setup] → [Vehicle] → [Drive mode customisation] → [Powertrain] → [Power] (Type B)

      3. Select CUSTOM mode.

      4. Move the shift lever to D or M. When the vehicle speed is 6 km/h (4 mph) or more and the engine speed is 980 rpm or more, check that additional engine sounds are generated in accordance with the engine speed.

        Tech Tips

        Check the difference in sound when the mode is changed between ECO (not generated), NORMAL (not generated), SPORT S (not generated) and CUSTOM (generated).

    3. Check intake flow noise generation


      1. Start the engine.

      2. Select SPORT S+ mode.

      3. Move the shift lever to P or N.

      4. Apply the parking brake and secure the wheels with wheel chocks.

      5. With the accelerator pedal opening angle below 10%, increase the accelerator pedal opening angle to between 15% and 70% and keep it within that range.

      6. With the accelerator pedal opening angle between 15% and 70%, increase the accelerator pedal opening angle by 15% or more in 0.01 seconds and check that intake flow noise is generated.

        Tech Tips


        • Check the difference in sound when the mode is changed between ECO (not generated), NORMAL (not generated), SPORT S (not generated) and SPORT S+ (generated).

        • To generate intake flow noise again, decrease the accelerator pedal opening angle to below 10%.
