Brake Control System - Abs: Description: Operation

When the vehicle speed is less than 10 km/h (6 MPH) this system does not work.
The Anti-Lock Brake System (ABS) has a self-test function. The system turns on the ABS warning lamp for 1 second each time the ignition switch is turned "ON". After the engine is started, the ABS warning lamp turns off. The system performs a test the first time the vehicle reaches 6 km/h (4 MPH). A mechanical noise may be heard as the ABS performs this self-test. This is a normal part of the self-test feature. If a malfunction is found during this check, the ABS warning lamp will stay on.
While driving, a mechanical noise may be heard during ABS operation. This is a normal condition.
