I completely unplugged both left and right working power steering control modules, i have plugged them back in but power steering doesnt work, do they need to be reprogrammed?

What is your question?

After a front end collision in my 2014 q50 premium, I had to replace some plastic components such as the bumper, brackets, supports and a few other small electrical things like sensors. To do this, I had to completely disconnect/unplug both left and right power steering control modules from the harness to gain access and replace the broken brackets. The power steering worked up until I unplugged them and they received no damage during the collision. So I replaced the brackets and plugged the PCM's back in,but now my power steering doesn't work and I am receiving a P0603 error code. I was hoping someone knows if these modules have volatile memory that stores information necessary for power steering, and if it was reset or lost due to loss of power for about a week while unplugged. I just don't see why that would be the case because people lose complete power to their cars for months all the time without having to get their PCM's reprogrammed but will mine need to be reprogrammed anyway?
