how do you troubleshoot the abs light on ford f150

Brenda, most of the time when your ABS. Antilock Brake System is on the problem is the wheel sensor. An that should fix the problem.

Occasionally, a sensor(s) gets caked up with mud and grime. Visually check and clean if required.

Check ABD fuse ti see if it's blown. There's a egr valve heater that's tied in to the same circuit, wire insulation burns out due to heat and it shorts out and blows the fuse to the ABS system.

Sorry but my manual has no description in the fuse diagram that says anything about ABS, EGR valve heater. I read somewhere that it was fuse 36 under the hood but I pulled it and no lights turned off. Perhaps there is no fuse for my ABS system, I have a 2010 F150. Can anyone help
