brakes on ‘91 Ford F-350, the RABS module to be more specific. What is the proper way to ‘test’ that module?
The rear sensor on the differential shows 1600(ish) ohms, from I been told, that is acceptable?
So far, have not found the cause of the ‘Rear Antilock’ light constantly being on. If it went for the cruise control unable to activate, due to this particular warning light, I wouldn’t worry, but no cruise cuts into the mpg.

I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science.

Check Third cab roof Brake light. The cruise current runs thru that circuit--it's goofy, replaced two light bulbs there and CC resumed working. LED bulbs in that location will not work.

Are you saying you have 'no cruise control' ?

If so ,was your truck recalled due to the 'master cylinder fire' problem and was 'fixed' by Ford ?

If so, then the fuse in the 'repair' has blown as the switch in the master cylinder has shorted to ground .

there is an EASY true fix to that problem that gives you back cruise control.
