2017 Silverado 4x4 crew cab U 1510 trouble code

[Mwatt1358]

 I have a 2017 Chevy Silverado with 51,000 miles.  Just got engine light a couple days ago, run a basic scan tool  to show the U 1510 code.  I am aware that there are sub codes, but this tool does not display those.  Doing some  research looking like it could possibly be the active grill shutters module..  I’m trying to avoid taking it to the dealer at the moment . Trying to do some more research first, because conveniently this won’t be covered under power train  warranty.  I did a basic test yesterday of the shutters, I unhooked the  connector and  applied power and ground and the shutters went closed.  Tried to check the LIN bus  Signal, but I have an old oscilloscope, so I really didn’t get and accurate waveform.  Searching the Internet, I have seen this has been a fairly common problem with GM.  My next step is to replace the shutter unit.  I hate to put out over $200 for something that might not be the problem but, if I take it to the dealership I’m sure it’s gonna cost a lot more than that, by the time they figure it out.  If anyone has any information on this problem, a response would be much appreciated. Thank you and sorry for such a long post.
