*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) 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 (see page 05-765).
*2:
(1) Keep the vehicle in a stationary condition for 5 seconds or more and depress the brake pedal
lightly 2 or 3 times.
(2) Drive the vehicle at a vehicle speed of 31 mph (50 km/h). Then depress the brake pedal strongly
for about 3 seconds.
(3) Repeat the above operation 3 times or more and check that the ABS warning light goes off.
(4) Clear the DTC (see page 05-765).
