Do something simple and free first. Remove ground cable from one batt and then go to the other battery and remove ground cable and touch to the positive post, it will not short or anything but it will drain capcitors in the control modules. Hold the ground to pos for 15 seconds and then hook up both grounds and see if the light goes off after you drive past 10-12 MPH.
Some control modules go offline and the capacitor in the circuit to stabilize voltage can keep it from powering down and resetting. I haven't known this to be a trick used on Ford's but your 05 has some CAN computer multiplexing. Other car makes with multiplexed CM's are often reset like this when goofy things occur.

 

did you find the problem? i just had the exact thing happen? been messing with it all day, new batteries alternator, rear vss sensor , still no speedo and abs light its on? pulling what little hair i have left out lol

 

I have a 05 f250 super duty with the 6.0 diesel an I was pulling a camper an the truck shutoff an the battery light came on asa the truck died. I have a code reader for the truck an it’s only throwing abs codes for the truck an not throwing anymore codes for my truck. What can I do to find out if anything else about it. It has fuel going to the engine an turning over.
