I finally got around to changing the steering rack today. Everything works as it should. Only thing is when you start the truck it gives a service power steering fault. All the other errors went away such as hill decent and another one but I can’t remember it. I tried loading the as built data with FORScan on the pscm but idk if I done it correctly. The power steering works. It just has that initial fault come up. You can press ok and it goes away until you kill the truck and start it up the next time.

 

The PMI procedure must be performed, and the PSCM updated to the latest calibration, when replacing the electronic power steering rack.
