When the "ABS" warning light is on (and the brake system warning light is off), the anti −lock brake system does not operate so that the wheels could lock up during a sudden braking or braking on slippery road surfaces. If either of the following conditions occurs, this indicates a malfunction somewhere in the parts monitored by the warning light system.
