Wheel Sensor 3rd Axle Left
- Check intermediate axle left wheel speed sensor and its fixing. In case the distance between pole-wheel and sensor (air gap) is too wide, push the wheel speed sensor back to the pole wheel to adjust the air gap - Check sensor wiring and connectors for intermittent contact. If using the WABCO diagnostic tool, read out amplitude of the sensor signals and make a comparison with required values. Remark: A repair can be considered successful only when the vehicle is driven again in order to detect possible dynamic failure.
