You will need to fix the brake light circuit first. A failure in that circuit can cause the ABS system to not self-test and to turn on the ABS light.
Most common reason for F13 blowing is the same fault that caused the cruise recall, leaky switch on MC.
Have you had your recall done yet? If not, DO read the dozens of threads, some with photos, AFTER you've moved the truck away from the house.

Had recall done about a month ago. Truck ran and opreated great up untill now. Truck has 226000 km and cruise was used extensively whiole obtaining current milage on truck. I tried to get informa1tion from Ford regarding recall at time when I took it in for the work but they weren't very helpfull. As best as I can tell the fix amouts to a 2 amp fuse placed in the line to the switch on the mater cylinder which is sill intact. Can't seem to access the threads that you mentioned in your reply, any tips on how this is done ( kinda computer illiterate) thanks for your input

It's good to know the recall was performed.
That takes the easy and most common solution off the table. What's left is the hard stuff, a short circuit in the brake light circuit.
This has the potential to be a real PITA to find. You'll need a schematic and a meter and start troubleshooting the wiring.
The fault could be anywhere from the BOO switch, to the column (MFS), to the rear corners or the HMSL, the shift interlock (if auto), or any one of the electronic modules that uses the brake light signal as an input.
If you're not comfortable tracing a short circuit, you should probably refer this job to a technician.
