  4. Drive the vehicle at 20 km/h (12.4 mph) or less, carry out the scan tool actuator test (item No. 05), and forcibly activate the ACD. Then, turn the steering wheel 180° or more to the right or left, and check that tight corner braking occurs.
    NOTE:
    • The forced activation (item No. 05: ACD operation check mode) is continued for 1 minute, then it will be cancelled automatically. Also, using the clear key on the scan tool, the activation can be forcibly cancelled.
    • When the ACD functions are stopped due to the fail-safe, the forced activation cannot be performed.
    • The occurrence levels of body vibration and noise caused by the tight corner braking phenomenon will differ depending on the conditions of tire and road surface.
    • If the tight corner braking phenomenon does not occur, the system may have an abnormality. Therefore, check the hydraulic pressure.
