2006 F-53. Doing brake overhaul found rear rotors did NOT have ABS rings in them. Both hubs have ABS sensors, this is a 4 channel system. I had no ABS light on. Stupid me went and replaced the rot...
No codes found. Cleared the fault (light off) and took a test drive. 1.5 miles the light comes back on, no codes again. Did this twice. New rotors coming in will put them on. Stealership won't look at it anyway unless all the mechanical stuff is correct.
