If any failure is detected which causes one of the above codes to set, the ANTI-LOCK light may or may not remain on, depending on type of failure. At low speeds, wheel sensor can set code, then clear itself. At high speeds, code will be set and remain set. Intermittent open in sensor cable can lead to code being set, then clearing itself.
