I know you ask this a couple months ago but doesn't look like anyone mentioned that if you have a SGM Bypass module and a program such as AlfaOBD or DiagFCA you can go in and change the default voltage output to almost all of your external lighting, which of course will make them brighter or...

Interesting update ~ I was talking with a customer today and talking about my new truck and about the soft-key for the rear camera disappearing and he said he has had the same thing happen on his 2019 model with the 12" screen, and he didn't think about it at the time but he has also used...

On my new 2021 Longhorn with the full surround camera system the other day after using the DiagFCA program to change something UN-related to cameras the next hour my Camera system would show a blue screen and say "Camera System Unavailable", well that actually seemed to have fixed itself the...

Well now that the cameras are magically working again all on their own how about another camera-related question... I have never messed with it, and never seen a setting that looked like it would affect it... But is there a way to keep the cameras either from timing out, or at least from...

OK, Very weirdly.... Had to run some errands in town, got dinner, came home. Still wasn't working. Loaded truck, washed it, still not working. After it finished drying went out to back up to the trailer, and the cameras are all back. No clue why or how, or why they went off in the first place...

I can try it but I will not have a copy of the original configuration from AlfaOBD because I wouldn't let me do anything last night.

I can send you the save file from DiagFCA, it looks kinda similar to the thing you posted a link to, I will try and send the original that I saved before I ever did anything and then make a copy of the current config and send to you privately if I can figure out how.

I'm not using AlfaOBD, I have it but not hardly any of the features was available or worked right with this 2021 truck so I had to switch to using DiagFCA

Do you mean where it lets you export a text file of the current vehicle settings? Yes I did that before I ever started, just printed it and went thru it line by line (though oddly many things in the actual programming are NOT in the printed list). Also, what is a "Google Drive File" ...

On my new 2021 Longhorn 2500HD Cummins 4x4 last night I finally got in my bypass for the security gateway, plugged it in, activate DiagFCA and tried to activate AlfaOBD (though most things in that one are not working) do so some simple changes such as preventing the fog lights from going off...

Do they make these for the 5th Gen (2021 Longhorn Limited Edition with the Offroad Package) 2500s with the Cummins? I know the turbo intake and cooler are down under there but don't know if they're in the way or not.

Did you ever get this fixed? If so how did they finally get it fixed? My 2018 Laramie 2500HD just started doing the same thing. Always worked perfect then yesterday morning I started getting that message first on some XM channels, then within an hour all of them and has been that way since...
