'01 Corolla U (L/O 0005) "ABS" warning light The light comes on when the ignition key is turned to the "ON" position. If the anti- lock brake system works properly, the light turns off after a few seconds. Thereafter, if the system malfunctions, the light comes on again. When the "ABS" warning light is on (and the brake system warning light is off), the anti-lock brake system does not operate, but the brake system still operates conventionally. Type A A warning light turning on briefly during operation does not indicate a problem. 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. Contact your Toyota dealer as soon as possible to service the vehicle. D The light does not come on when the ignition key is turned to the "ON" position, or remains on.
