Yeah, going off what everybody else is saying, I would 100% go back and check the connections on the wheel speed sensor going into the hubs. If everything looks good there, get ahold of an OBD 2 scanner with ABS reading scanning feature and see if it’ll throw you a code and narrow it down.
Not discounting your knowledge at all, so don't take offense, but where are you going with this. Sometimes I'm not careful enough, and I actually learn something.
When I did my gears while it was on the lift I ran it at idle to look for any issues or sounds. It threw many error codes on the dash like the OP because all 4 wheels were moving at different speeds but as soon as it was driven all was fine. I knew what it was so I wasn’t worried. It occurred to me that if the OP was working on a lift he may have run it to check for binding.
Gotcha! That's never happened to me yet, I've never run it like that either. Makes sense what you're saying, and certainly worth keeping in mind. Thanks.
so I put the leveling kit back in today successfully. So it was totally my fault and I should of known better. All I had to do was unplug the battery before I started and plugged it back in after. The problem the first time was exactly that when I unplugged the speed sensor the battery was still connected and was reading that it was not working even when I plugged it back in.
Hopefully that was it. When you disconnected the battery for the length of time it took, you, in effect did a KAM reset as well. I bet it shifted different and the throttle felt different?
what what worked for me was undoing the battery and letting it sit for 10 mins then plugging back in
tried that, removed connections to battery, for 4 hours, discounted pos/neg cable tried touching together ( per ford) got nothing,, so here i sit at ford waiting for them to reflash the truck.
