Mac Willer It’s a nice feature. I’m glad they offer it

Thanks! I’m glad you enjoyed it. See my playlist on this truck here ru-vid.com/group/PLIjr-uSYDZi7J7EQ1ErTn1Yzi6ET_3Ssr

I have a break-away setup with a similar switch/cable. The cable is maybe 12 or 14 guage braded steel. I use mine every time, looped through the chain loop and back to the trailer. It's funny though, the way it is, if the chains were to fail and the only thing holding the trailer to the truck is that little braded steel wire, my money goes on the wire breaking. Then, the trailer won't do any braking. Weird design. Edit: Nevermind, I now realize there is a pin that gets pulled out, and when that pin pulls out, the brakes are applied.

Thanks! Feel free to see my others on this truck here ru-vid.com/group/PLIjr-uSYDZi7J7EQ1ErTn1Yzi6ET_3Ssr

@@dannyjohnsonsgarage Hi, just wondering how to get the trailer gain icon off the dashboard. I accidentally press the button but don't know how to take the trailer gain off.

Thanks. See my playlist for more features ru-vid.com/group/PLIjr-uSYDZi7J7EQ1ErTn1Yzi6ET_3Ssr

arlingtonguy54 I’m glad you enjoyed the video. Thanks!

It shouldn’t unless you notice it’s taking too much effort to stop. At that point add more gain, but just make sure the wheels are not locking up

I would try looking up a model number of the trailer

Yes, the Denali gets you the larger digital center screen, which is nice. When you hit tow/haul the trans temp swaps in as well. Nice features

It should be the same, perhaps without the battery it’s just a different break away safety system

Same question here. I have some doubts.

That is "tow/haul." It just changes shift points to give you more rpm in each gear before shifting, turns on the radiator fans sooner to keep the engine cool. The plus/minus is for manually shifting gears.

Leo Reyes In perfect weather at high speeds, just go with 2wd.

It typically works that way. It may depend on the trailer and how it’s setup.

Tow/Haul mode is for the truck to change shift points and engage cooling fans etc and the trailer gain is how hard the brakes will be applied on the trailer. The two systems will not know the weight of the trailer, so tow haul will always act the same and the trailer gain is set by you depending on the weight of the trailer. The video shows how to set the trailer gain

It should not be doing anything between shifts. You can manually apply the brake so you know it’s in and see how it does between shifts. My thoughts are a camper may be a little much for a GMC Canyon ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HwBqdogG-uc.html

Man I wanna give you the truth and that's it! The reason your vehicle is lurching has everything to do with the weight of the trailer versus the weight and power of your vehicle. Zero to do with the brakes! Period! Your towing vehicle may be too lightweight. Not meant to be an insult but ya gotta have weight to pull weight. If you have a tow/haul switch, USE IT. If not, it wasn't designed to be a tower in the first place. Not to say that larger vehicles automatically are set up to tow but just a general statement. Do this.... Open the owners manual, that's the trucks bible. Trust it. Glossary - Towing - Towing Capacity and get that number, the gross weight one, aight? Lets say your owners manual states 1500 pounds, for example. Now, tow the trailer loaded, fuel and all and hit a truck stop or a city dump. Get on the scale with the trailer and then without the trailer attached. I bet you'll find that the trailer is too heavy for your vehicle or it's darn close and coupled with lack of torque. And if not, I will take the hits but that's the ONLY actual and accurate way to know what you can tow anyhow so it's money/time very well spent! You seriously do not wanna be towing a trailer that's too heavy. See what I mean......

In all seriousness this was very informative! Adjusting the breaks today pulling a full size SUV was a breeze.

You can change the gain value while driving

poot111111 Yes. I have actually said that very thing lol (and if the explorer was the 5.0...maybe that too). I do really like the Yukon as well though- styling and features. I also suggested a 6.2L raptor, but my wife wasn’t on board ha ha

That has not happened to me. I can access the info at any time, but it is dim until hooked up

You would need to verify if the harness for the vehicle has the plug for it to plug in, and then it still may need to be programmed. My friend had both on his Ford, but I was pretty sure it’s not the case for GM.

Coasting should be fine, the idea is to see if the brakes lock up. They should look easier without accelerating, so it would be better to know if they lock up under no throttle (which would be more likely the case when you are applying the brakes in a real life situation without the accelerator), but that’s just my guess. Verify it with a more reputable source

The top slide manually applies the brakes. The gain is from the +\- buttons

It won’t matter because the number is how hard the trailer brakes are being told to apply, but I would leave it on 5 so when you hook up you don’t forget and Lock up the brakes on the trailer

Yes. It recalibrates the transmission shift points, usually activates the fan earlier, etc

Word!!!

Sure hope you have that coiled cable hooked up as your driving. That pulls the pin out of that safety box, thus applying the batt to your brakes in the event of a towing separation.

It did not come with that as part of your tow package. You can add one. www.amazon.com/Tekonsha-90195-Electronic-Brake-Control/dp/B000P17NXQ?keywords=gm+trailer+brake+controller&qid=1646413911&sprefix=gm+trailer+brake+,aps,126&sr=8-2-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFQTzQzWjMwOFhSU0YmZW5jcnlwdGVkSWQ9QTAzMDY2NTRVVzVLWFpRVERDTVAmZW5jcnlwdGVkQWRJZD1BMDg3NjQ5NE9ZSElPSlkzM0U1JndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ%3D%3D&linkCode=sl1&tag=2004047-20&linkId=ac18d02aacd40edce8215b280236cd55&language=en_US&ref_=as_li_ss_tl

You can delete the page from the dash until you want it, or disconnect the negative battery cable for 5 minutes and hope it resets ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ZkRws7Z1L4U.html

You’ll only be able to tell if it has power. I don’t think you’ll be able to know without hooking it up

Danny Johnson’s Garage do you know if you can install this part without a brake controller already factory in the car?

The brakes on the trailer will automatically be applied when you push on the brake pedal. The gain amount is how hard the brakes are applied on the trailer. There is also the manual brake switch to apply only trailer brakes if you want, but otherwise just push the brake pedal and it does the rest for you 👍🏼

Bea, Honey dog and me I’m not sure if this is all you would need, but here is the breakaway attachment. The people at this company could probably tell you why exactly you would need www.amazon.com/gp/product/B07YD5Q2MV/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=2004047-20&creative=9325&linkCode=as2&creativeASIN=B07YD5Q2MV&linkId=396dc598241bfc232ea3bae18d0a5869

@@dannyjohnsonsgarage Thank you. I'm just seeing your reply. Appreciate it.

Bigfoot Llamas The trailer needs a battery including it’s own brake system. Not all trailers come with brakes so you’ll need to see what it has

If you have the trailer brakes on the truck set at 10 and you manually push the brake switches together and nothing is happening, it’s more likely something is not right on the trailer end. Try setting it to 10 and put the truck in drive. As you slowly move forward does the trailer brake do anything at all?

I guess that's the problem. It has the towing package but I don't see any manual controller to make any sort of adjustments. Seems odd to me that a truck would come with the trailering package but not the manual controller.

There is a tow package for the hardware, but if you don’t have the buttons it doesn’t have the brake controller. You can purchase them aftermarket and install

@@KellerWilliamsCovina I have a 2020 TB with the tow package. The controller sits on the left side of your front USB ports. Near your right knee.

Yeah, that’s why the video discusses setting it for different road conditions and weights as well, i.e pavement, gravel, loaded, unloaded

@@dannyjohnsonsgarage For sure! I thought it was a great video, saved me time flipping through the owner's manual of my '23 Sierra. I just thought it was worth mentioning again in a comment, because many viewers seemed like first-timers with brake control. Well done!

I have a 2022 tahoe rst

It should only be on if you’re squeezing the handles to stop the trailer. If a trailer is not connected it doesn’t matter
