Problem: Vehicle description: school buses, medium duty trucks and tractors built with bendix air ABS with an ec-17 1030R electronic control unit (ecu), there have been reports of unwanted ABS activation at low speeds caused by 1) chafed ABS wheel speed sensor wires on rotating parts or 2) a damaged component at the wheel end that generates a certain type of erratic sensor signal.
Risk: This condition could cause the ABS ecu to exhaust the air at the air brake modulators for one or more of the wheels. This could result in extended braking distances and a possible crash.
Fix: Dealers will replace the ABS ecu.
