(1), (2): Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed. (1): Drive the vehicle at 20 km/h (12 mph) for 30 seconds or more and check that the ABS warning light goes off. Clear the DTC. (2): Keep the vehicle in a stationary condition for 5 seconds or more and depress the brake pedal lightly 2 or 3 times. Repeat the above operations 3 times or more and check that the ABS warning light goes off. Clear the DTC. HINT: In some cases, Techstream cannot be used when the ABS warning light remains on. When U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 is output, inspect and repair the trouble areas indicated by these codes first. (*3): The skid control buzzer sounds.
