JR ! I just got the truck back from the Dealership today . The technician did a cold remote start on the truck this morning and it made the noise . It was determined that it was a starter issue and replaced it under warranty . Of course it did not make the sound after a new starter was put in because the truck was not cold . We will we see what happens tomorrow morning when I start the truck cold . Keep tuned !
Oh I found a video on YouTube of a cold start and it did the same thing your truck and mine do ,
I will see if I can find it and post it up
'22 Sierra 2500HD.
Just want to confirm,
Am about to replace the Trailer Brake Control Module (the thing above the spare tire), and then may replace the Trailer Brake Controller (in-dash device).
I understand, at least for the Module replacement, that the vehicle battery needs to be disconnected.
So, a couple questions - Is it necessary to disconnect the battery for both procedures? - Is there a difference, in any resultant electronic issues, on how long a battery is disconnected? IE does it matter if the battery is disconnected for an hour as opposed to over night? - And, for replacement of both items, is there a requirement to "re-boot" any system(s). I have been led to believe that the Module is less of an issue than the Controller, but it has been suggested that a trip to the dealer may be necessary after the Controller is replaced.
Any advice is welcome.
