Abs light but no faults

Hi sorry if this has been asked before but I'm a bit stuck, I've got an mot coming up on my 1999 rover 45 and thought I'd better get my abs light sorted. It comes on every now and again along with throbbing threw the pedal so I checked and replaced the cv joint because of a cracked exciter ring, however since I've replaced it the light is now on permanently so I use a snap-on solus pro to scan the abs system but there were no codes present this left me scratching my head and I was wondering is there any way of clearing this light before my mot is due and if so what's the procedure! I've tried driving it fast/slow breaking heavily and light! The abs works fine but the light is still on.



Any ideas?
