I have a transit and it’s showing the abs light and will also tell you brake assist not available. Plus the traction control won’t turn off when you press the button. I hooked it up to a code reader and to FORScan lite and there are no codes to go by. All wires to wheels look to be in good shape. Any idea where to start? Van is a 2019 250, bare bones work truck.

 

To update this, i found an obd2 app that does abs, it showed back wheel tuning ring fault. Easy to change, but you need to pull axle. Just jack it up high and you dont lose fluid.

 

This must be a common problem in Transits.
I’ve read this several times on FB Transit camper build page.
