my abs fault light keeps coming on?(picasso 1.6 petrol 2002)?

Have a look at the phonic sensor ring on the drive shaft. I have seen a few broken ones. If you turn the steering to full lock left or right then look where the drive shaft goes into the hub you will see what looks like a cog. Check to see if its loose. Both sides.Hope this helps.

The ABS computer should have the answer. The light coming on should set a fault code. Codes need reading and maybe a look at live data. As the pedal is pumping its my guess that its seeing a stationary wheel. This may be just a build up of brake pad dust on the wheel speed sensor.
