all the DAFs I have driven over the years have all had ABS warning lights come on,seems to be a common fault with these vehicles,our senior fitter said us drivers are not connecting them correctly,so he disconnects the ABS off my unit and put’s it back in and say’s it should be ok now,5 min down the road and I get the usual,EBS/ABS trailer not connected coming up on the dash,he put’s a new lead on and it still comes up on the dash after a time,doubt if it will ever be sorted,and mine’s a 66 plate
