I have only seen the C056D code related to the Power Steering. In some cases, the factory recommends replacing or reprogramming the Power Steering Control Module. The C056D code may not be related to the symptoms you have.
Have you tried clearing the code? Do you have any other codes?Reply here: https://www.autocodes.com/c...

Suddenly lost power steering in my 2017 Cadillac XTS. Dealer diagnosed with C056D 39, power and ground was good to the control module. They wanted to replaced steering gear assembly due to a failed power steering control module but gear assembly(84494618) is on back-order until who knows when. Wouldn't reprogramming or replacing the power steering control module fix this?
-
Yes, reprogramming the control module will fix the problem. There is even a factory service bulletin for that problem. Here is the link to the bulletin: https://www.autocodes.com/t...

" steering assist is reduced drive with care"
steering get jammed then became alright on its own. Signal gain came and DTC was C056D. Service center is telling to replace entire steering assembly -
Since you also have a code, the issue sounds more like a problem with the steering control module and not with the gear. Let me see if I can find more information, what model and year is your vehicle?
