Looks about right given the data provided. Could it be better? Perhaps. But in spec isn't going to get it that way under warranty. -
'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. Marv -
I usually upload to youtube then paste the link here. I haven't done it here but it worked on other forums. -
