Mercedes sprinter ABS
I had the same problem close to St. Louis 2 days from home. Went to Mercedes dealer and work was done under warranty. Would have been over $700. The rear wheels have sensors the wire either broke or came dislodge some how. Ours was caused by rough road. We were going to Yellowstone so I had it fixed. Suggest you do also. Not sure if you are still under warranty. You have 3 years from your in service date , /.Not the production date
