Abs fault

[Saggy]

Help! Abs light on, tcl says off and skidding car light flashing. Started as intermittent fault, now as above. All reluctor rings good. O/s/r ring replaced as was cracked. All sensors magnetised. Can reset by disconnecting battery but tcl will still say off and fault comes back.
Any help much appreciated!

What does the Flashy Dash (https://www.clubvr4.com/forum/content.php?177-Reading-the-VR-4-s-Diagnostic-Codes-The-Flashy-Dash-Technique) give you for fault codes?

You say that all the rings are good, but this is typical of a failed ring or sensor - use the fault codes to figure out which wheel it is at least!

What Garry said - a tiny crack in the ring can give exactly this. The flashy dash will tell you which wheel is giving the issue assuming it is not something else. Note the error code will suggest the sensor, but the sensors failing are very rare - it is almost always the reluctor ring.
