My hats off to you wrench pullers that can diagnose any of this new stuff. Wife jumped in the truck to go to work this evening, and she came back in and said there is something wrong with the truck. I went out and got the big wrench, and the advancetrac warning plus a downhill descent fault. I did what any good operator would do, I shut it down and started it again. No luck, I'm stumped. drive it. I went on line and found horror stories about the same thing, plus signal lights not working, and leading up to changing the rack and pinion. A dealer job as the unit has to be calabrated to your truck when it is installed. Then I remembered, that I had just changed the air filter, and unplugged the MAF sensor to do so. At that moment, my dog ran out to see my young spandex wearing neighbour walking her dog. I didn't remember plugging it back in. Wife calls from work, said truck worked bad, and she was not driving it home. Told her to open the hood and take a picture and send it to my FB. Sends picture. Another one more to the right. Not plugged in. Dam small head, stop distracting big head. Explained how to plug in with red tab on bottom, then push red tab in. Light out, everything works fine. Never in my life would I figure that a mass airflow sensor would affect traction control, and signal lights. Never should have got rid of points and condensers.
