Not uncommon, this one......best to check the abs wires to each wheel, look for disconnection or damage to the reluctor wheels on the front driveshafts.
Good luck!

Or take it to local garage and ask for diagnosis.

ih, Perhaps not immediately helpful, but don’t exclude the possibility that the ABS wires and adjacent cables may have been chewed by wildlife. It’s worth getting whoever is best placed to have a recce underneath the car to look for random bite marks along cables mounted on the back axle/suspension (rear) and those running to the front wheels. My neighbours and I were plagued a couple of years ago with the same problem. Never worked out if it was rats, fox cubs or whatever. FYI, this problem is more widespread that most people are aware of. Best of luck to the car owner.
