If a diagnostic device or the car detects a fault in the ABS system it may or may not be able to say exactly what the problem is. Either way it will involve getting your hands dirty and having a look see - first things to check are the ABS sensors and reluctor rings are are clean and intact and no signs of split rings. Following that it may be prudent to check the multi-plug connection to the ABS controller unit is secure and clean.
No diagnostic system can tell the difference between a duff connection and a duff component.
A mate of mine took his car to a dealer (non Renault) and they diagnosed a faulty ABS unit and after 500 plus he was no better off - it turned out to be a cracked reluctor ring which he was able to repair using two-part epoxy adhesive. It seems they took the most expensive option - nothing new there now is there!!

Even something a simple a bit of grunge blocking one the teeth in the reluctor ring will bring up a fault
