Ford Explorer 2013 XLT
 “I replaced the steering wheel control module and then programmed it. After a while, the steering stopped working, and the following codes appear when I scan: 
— C1B00 86-28
— U3000 49-48
— U0100 00-48
— U3000 61-8A
— P07AE 09-C8
— U0415 00-48 
When I reprogram it, it works again, but after some time, it stops. I suspect there is an issue with the connections.”

Hey harth! Do you recall which modules set each of the fault codes that you listed?

I replaced the steering wheel control module and then programmed it.


By steering wheel control module, do you mean that you replaced the Steering Column Control Module? Or, did you replace the Power Steering Control Module?

After a while, the steering stopped working, and the following codes appear when I scan: P07AE 09-C8


When you say the steering stopped working, you mean that the power steering assist quits, right? That'd go along with the P07AE setting in the PSCM. I snipped this bit about P07AE from service info:

 

Basically, the PSCM is seeing that the steering assist motor is having to work too hard to provide power steering assist. Service info doesn't say how it measures that, but I'm inferring that it's measuring assist motor current.

You're looking for anything that can make the steering harder to turn. Binding strut mounts, bent suspension, seized ball joints, like that.

If you don't find anything wrong with the steering/suspension, then it's down to a failing steering rack assembly. This is usually where P07AE ends up, in my experience.
