So I just bought a 2014 e350 and it has a power steering malfunction as well as interior lights don’t work and infotainment system either and the steering is hard I can’t drive it I have these codes from my scanner and I need to be pointed in the right direction the power steering rack was replaced as well as the alternator is good and I changed out the main and auxiliary battery and entire front fuse box please if anyone knows the issue would be really helpful
Hard faulty STEERING lands in the ballpark of dangerous collision...
It's not currently clear what is disrupting your new rack operation. The rack is self-reliant with an internal steering input shaft sensor.
Many valuable parts were replaced with limited results. Now its time for some troubleshooting.
A full chassis scan should be used to have a better chance at diagnosing this right. If not then you will be up for a Xentry job. Let's see what other modules are acting up...
Needless to say you did check the rack harness-side connections are free of oxidation crusties.
(disconnecting logs faults!)
Did "replacement rack" get coded or just bolted on??
2x racks can't be bad, right?

Related to your use of AUTEL Scanner...
FYI: This scanner will give a rack communication fault with engine is not running... meaning its a sort of "false fault" caused "operator error" condition.
Run the engine to enable normal RACK functions over CAN + STERRING WHEEL response.
"IGN:ON + ENG:OFF" = Non responding rack - Normally expected!!
Why... this generation of Racks are power hogs that requires high power from engine running ALT, not battery only.

It’s a new OEM rack and pinion not sure why it should be causing problems and I’ve heard it needs to be programmed to the car is that true because that wasn’t done and if it is what scanner can I use to program

This requires an active Xentry system or a professional scanner with active subscription.
(Not just a $150 handheld scanner).
