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