ABS FAULT lights

[NJB1963]

Hi I have a problem with my ABS lights coming on ( Yellow warning lights )
I have checked the sensor ring and changed the sensor, the brakes work fine and the fluid level is correct
But the warning lights still comes on on the Centre section and the right hand side section of the instrument cluster.
The STRANGE thing is that it happens 90% of the time at the same place / distance after driving home from work after +/- 60 Km, and on the same piece of road when I exit the highway onto the smaller road so going from +/- 110Kmph to 50 Kmph
It does not do it on the way to work ?
After turning off the car and restarting it they do not come on ?
Can anyone help ?
Thanks in advance
