Normal operation
The ABS operates at speeds above 3 - 6 MPH (5 - 10 km/h). The speed varies according to road conditions.
When the ABS senses that 1 or more wheels are close to locking up, the actuator rapidly applies and releases hydraulic pressure. This action is similar to pumping the brakes very quickly. You may feel a pulsation in the brake pedal and hear a noise from under the hood or feel a vibration from the actuator when it is operating. This is normal and indicates that the ABS is operating properly.
However, the pulsation may indicate that road conditions are hazardous and extra care is required while driving.
