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 wheel speed sensor for correct voltage output (sufficient voltage output?) - Replace the ABS-ECU, if sensor and air gap are correct (this is the last thing to do !) Remark: A repair can be considered successful only when the vehicle is driven again in order to detect possible dynamic failure.
