how can i fix my picasso abs system?

I had this problem. Took it to Ciroen main dealers (bought car there 7 years ago).
They first cleaned the wheel sensor but no joy (free of charge whilst having annual service and MOT).
Then replaced the ABS Sensor - Joy of joys it worked a treat!
Cost me £150 including sensor. very pleased.
