Trailer Profile Light or Heavy Trailer

[Higginsc41]

I couldn't find a post about this so I am starting one. When I originally set up the trailer profile, the truck provided me the option to set up the trailer break for a heavy or light trailer. Having now towed a few time, I went in to change it to a heavy trailer, and the truck no longer gives me the option. I tried setting up a new trailer profile, tried change trailer type, and hitch type, but the option to select heavy or light trailer for the trailer break is no longer available. Has anyone had this issue and if so how did you fix it?

What year and model is your truck. You have a heavy duty truck and not a 1/2T right?

Sorry, thought I had added that. It is a 2024 3500 LT with less thank 2K miles on it

I need to look at mine. I don't recall having two settings.

So the funny thing is, when I first set it up, it gave me the option, which I picked light trailer, per the weight definition, and need to change it because the trailer needs the higher voltage or amperage to make the trailer breaks more responsive at a lower gain. I have tried setting up new profiles for every available trailer type, but the option still does not come up anymore. I am wondering if Chevy pushed an update to the app that removed the option, or if there is a software issue.

If you add truck info to your avatar and/or signature it won't be necessary to add every time you post.

 

 

I have profiles setup for 4 different trailers. 

I don't recall ever seeing the light/heavy trailer type thing -- but maybe I've missed it or forgotten.

 

Anyway, why can't you just adjust the gain to suit the trailer used with that profile.

Trailering app should save the last gain used for the profile.

Should be checking/verifying the brake gain setting each trip anyway -- to be sure brakes are connected and working,  that the gain is correct for the load on the trailer for current trip.

 

Interesting thing I found when changing from the a '21 truck to a '23 -- the profiles from the old truck showed up on the new truck. I assume this way done by the GM phone app and onstar. 

 

Two of my trailers use electric brakes and two do not.

Trailering app does keep track of the number of miles each trailer has been pulled (or the number of miles the profile has been used, since operator must select the profile to be used) -- useful for trailer maintenance timing

It also tracks the mpg for each one.

I'm on my 2nd 2024 and I don't remember either having that option.
