2020 - 3500HD Duramax @4000 miles

2018 - Jayco Northpoint 5th Wheel

2016 - Ranger Z518 Bass Boat (Surge Brakes)

 

Sometimes when I hook to the 5th wheel I get the error "Brake Gain Not Recalled".  When this error occurs it also feels like the brakes are not being fully applied when manually overridding (for a brake check).

 

Dealer has had the truck twice now , this time for 2 weeks.  GM is telling the dealer that both my trailers have bad wiring.  I did not have this issue with a 2018F450 pulling for 2 years.

 

Has anyone else seen this issue?

 

Thanks

I get that error all the time. Sometimes shortly afterwards, I’ll get a message saying that the brake controller has been recalled.
Even if I don’t get that second message, when I confirm the controller setting, the preset output is always at the correct setting anyway.

I just associate it as one of the numerous glitches that this system had.

same here, I get the error about every 4-5 trailer connections, but other than dismissing the screen, the gain is set correctly, and everything works fine.

Ditto the above.  I find everything works best if the ignition is off when I plug in the pigtail. However, I've never had the trailer brakes not work properly regardless of the DIC message.  I just ignore the message if it says brake gain wasn't recalled.

Yes, like others have stated I get the error but it still sets the gain properly. 
maybe next update will fix it.

I’m in same boat as the rest here... but it only does it with my 35’ cougar all other trailers it hooks up fine.

There is a recall on the 1500 that I have I know for the break controller. I bet the HD are having the same issue.  I called to see if I needed to have it looked at before I pulled my trailer, the tech said it did not effect the operation of the break controller. Just if there was a perfect storm of things that happen, if I remember correctly, he said something like this would happen. I too get it regularly and always seems to be set the same.

Also a regular for this issue.  Hope GM is actually working on it!

Ditto, it has a mind of it's own

ITBS system is not quite ready for prime time. Taking my truck and camper to a RV tech to see if he can make it work.  Trailer brakes connect intermittently.  Some times I get the trailer brake gain not recalled.

Like everyone else, I also get this issue.  Occasionally it will even say "no trailer connected" but the brake gain still works.  When that happens, I shut the truck off and restart it and everything works fine (this has only happened a couple of times).  I figure it is a software glitch and hopefully a future update resolves it.

Ditto for me as well, I have had a few brake gain messages...but the trailer brakes always work.....but I always check before getting under way.

    • Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.       
    • We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper. 
    • Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money". 
    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
