- Check pole-wheel at intermediate axle right wheel for damages. - Check sensor wiring and connectors for intermittent contact. - Check fixing and mounting of the intermediate axle right wheel speed sensor (Can vibrations cause chattering?) - Check foundation brake for inadmissible vibrations at intermediate axle right wheel (return spring defect?) - Read out amplitudes of sensor signals and compare with required values. Remark: A repair can be considered successful only when the vehicle is driven again in order to detect possible dynamic failure.
