The steering gear (or steering rack whichever you want to call it) is an assembly that includes the PSCM (power steering control module) being that it is a new computer module it has not had any parameters programmed into it and a VIN assigned. If they have not done that I would bet that is your likely solution because the PSCM sends and receives data from multiple other computer modules. If they have not yet discarded the old its an easy fix. Plug in and copy paste basically otherwise I don't know how to go about telling it all the required parameters to match how your vehicle was configured (options such as lane keep assist or pro trailer back up or parallel park assist etc change what the PSCM needs to communicate with so new steering racks come with a bare bones programming in them to allow them to function and communicate)

I tried everything and could never get the errors to erase. I ended up taking it to the dealer and they programmed it for me. I think it was around 100 dollars max for them to do it and clear all the errors

I didn't have the dealer replace it. At the time, they told me they were so busy they couldn't get me in for about a month. I found a local shop that would do the work. They let me purchase the new rack myself from online which saved me some money, they put it, but they lacked the experience and know how to update it so the computer recognized everything.

How'd you determine it was going bad? How long had the problem been persisting?

Is it possible to know if the rack and pinion has been replaced in the past on a particular vehicle? Will diagnostics show if it was previously reprogrammed? Looking at buying one and it's on the 2nd owner so he doesn't have full service records for it. Just wondering if it may fail on me soon.
