So I have an issue with the abs and tc lights comin on, on the dash. If I plug in a code reader it reads no faults at all. But this could be because it's just a amazon jobby. And wont read the car, although it worked fine on my other halves focus, but not sure if a 08 focus uses a canbus or not. However. The lights only seem to come on when the car is stationary at a set of traffic lights etc. And turns off if I quickly switch the car on and off again. Sometimes the lights dont come on at all. And sometimes they come on everytime I stop. I recently changed my brake pads, so wile I was doing them I took the sensors out and gave them a clean with warm water, but the problem is still the same. Any body else had a similar issue.
