Vehicle speed control:accelerator pedal
Problem: Vehicle description: class 8 trucks equipped with felsted electronic accelerator pedals. The return springs can break on the accelerator pedals that are equipped with stainless steel or electroplated wire return springs.
Risk: This condition could cause the pedal to go to full throttle if both return springs break, increasing the risk of a crash.
Fix: Replacement accelerator pedals equipped with return springs manufactured of music wire with one additional coil on each spring and with an organic coating, eliminating electroplating will be installed.
Service brakes, air:antilock
Problem: Vehicle description: heavy duty trucks 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.
