  1. Drive the vehicle at the speed of 31 mph (50 km/h) and depress the brake pedal strongly for approximately 3 seconds.
  2. Repeat the above operation 3 times or more and check that the ABS warning light goes off.
  3. Clear the DTC.

HINT:
  1. In some cases, the intelligent tester cannot be used when ABS warning light remains on.
  2. When U0073/94, U0100/65, U0123/62, U0124/95, U0126/63, U0130/68 or U0131/67 is output, inspect and repair the trouble areas indicated by these codes first.
