*1, *2:
Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed.
  1. *1:
    1. Drive the vehicle at 12 mph (20 km/h) for 30 seconds or more and check that the ABS warning light goes off.
    2. Clear the DTC.
  1. *2:
    1. Keep the vehicle stationary for 5 seconds or more and depress the brake pedal lightly 2 or 3 times.
    2. Drive the vehicle at the vehicle speed of 31 mph (50 km/h) and keep depressing the brake pedal strongly for approximately 3 seconds.
    3. Repeat the above operation 3 times or more and check that the ABS warning light goes off.
    4. Clear the DTC.

HINT:
In some cases, the intelligent tester cannot be used when the ABS warning light remains on.
