Steering assists reduced

[Htown_LTZ]

So I recently installed aftermarket tow mirrors on my 2017 Z71 LT. When I went to turn it on to check if everything was working, this popped up in the screen "steering assists reduced, please drive with care" or something. I checked all my wiring and everything seems to be fine. I disconnected the negative battery cable for about a minute but it still came up. Anyone have any idea why this is happening?

My ‘17 Sierra started doing this randomly a couple weeks after I had a level kit installed. Took it to the dealer. They didn’t explain much, but they said there was a TSB for it and something had to be reprogrammed. Easy fix, had my truck back in about 20 min.

If you have a decent code reader, you might be able to clear this message yourself.

 

I got this message after installing my heated steering wheel.  It wouldn't go away...I used my EFI live as a code reader.  It did not read any codes but I did a "clear codes" anyways and it was then gone.  It hasn't been back since.

 

Good luck.
