Is there any dust in the punching ring that affects the abs?
What you say is the 4S shop to shirk responsibility, your car is still in the period of three guarantees. In addition ABS lights, the fault is detected, without a clear definition, as you are. You ABS lights and anti-skid lights, either inductive head is not clean, or the sensor is broken, either the bad contact line.
When the gear ring is contaminated, the sensor will misread the signal and assume that the relative two wheel speeds are inconsistent, resulting in sideslip, and the ECU will give the side braking signal to keep the speed consistent. Reflects the driving is vehicle deviation.
Yes, the stamping ring on the wheel hub is not clean and has an impact on the operation of the ABS.The ABS sensor is used in motor vehicle ABS (Anti-lock Braking System anti lock braking system), ABS system mostly by the inductance sensor to monitor the speed of ABS sensor through the ring gear rotates synchronously with the action with the wheel, output a set of quasi sinusoidal AC signal, the frequency and amplitude of the wheel speed. The output signal is passed to the ABS the electronic control unit (ECU), to achieve real-time monitoring of the wheel speed.
