Last Updated on January 30, 2023 by Ryan

The Service Trailer Brake System message may be displayed when the trailer brake system is not working properly. This message is intended to notify the driver that the trailer brakes are not functioning and may cause the vehicle to become unstable.

The 2015 GMC Sierra comes with a new service trailer brake system. This system allows the brakes to be applied when the trailer is being towed, even if the vehicle is not equipped with a trailer brake controller. This can be a great feature for those who frequently tow trailers or who live in areas with hilly terrain.

The service trailer brake system can also be an excellent safety feature, as it can help to prevent accidents and injuries that could occur if the trailer were to become detached from the vehicle while in motion.

How Do You Reset a Trailer Brake Controller?

If your trailer brake controller isn’t working properly, you may need to reset it. Here’s how to do it: First, make sure that the trailer brakes are in good condition and that the wiring is connected correctly.

If everything looks good there, then the next step is to reset the brake controller. To reset the brake controller, first disconnect the power supply from the unit. Then press and hold the “Set” button on the controller for about 5 seconds.

After that, reconnect the power supply and test the brakes to see if they’re working properly. If they’re still not working right, then you may need to take it to a mechanic or an RV dealer to have them take a look at it.

What Does Trailer Brake System Mean?

When brakes are applied to the trailer wheels, the tongue weight transfers to the rear axle of the tow vehicle and creates a braking moment. This braking moment is transferred through the hitching system to the front axle of the tow vehicle where it is resisted by tire friction. If not for this transfer of weight, most vehicles would have difficulty stopping a fully loaded trailer.

The amount of transfer depends on several factors including: -The weight of the trailer -The distribution of that weight (tongue weight)

-How much friction is available between the tires and road surface -Whether or not anti-lock brakes are used -The efficiency of the hitching system in transferring braking force.

When considering these factors, you can see how different trailers will act differently when brakes are applied. Heavier trailers will require more braking power than lighter ones and those with less evenly distributed weights will tend to be harder to stop as well. The type of terrain (sandy, muddy, etc.) can also influence how well your brakes work since tires may slip more on some surfaces than others.

How Do You Turn off the Brake Assist on a Gmc Sierra?

If you need to turn off the brake assist on your GMC Sierra, you can do so by following these steps: 1. Press and hold the “Vehicle” button on the instrument panel for about five seconds. 2.Release the button when the word “Menu” appears in the display.

3. Use the arrow buttons on the instrument panel to scroll through the menu options until you find “Brake Assist.” 4. Press and hold the “Set/Reset” button until you hear a beep. This will confirm that brake assist has been turned off.

How Do You Troubleshoot a Trailer Brake Controller?

There are a few things you can do to troubleshoot your trailer brake controller. First, check the fuse for the controller. If it is blown, then replace it and see if that fixes the issue.

Next, check the wiring going to and from the controller. Make sure all connections are tight and there are no loose wires. If those two things don’t fix the problem, then you’ll need to take a closer look at the controller itself.

Check to make sure all of the connections inside the controller are tight. You may also need to replace some of the parts inside the controller if they are not working properly.

Service Trailer Brake System Gmc Sierra

The service trailer brake system on the GMC Sierra is designed to provide extra braking power when hauling a heavy load. When the system detects that the vehicle is starting to slow down, it automatically applies the brakes on the trailer, providing additional stopping power. This can be extremely helpful when travelling down a steep hill or in other situations where extra braking power is needed.

The system can be turned off and on as needed, and will automatically disengage when the vehicle comes to a stop.

2015 Gmc Sierra Trailer Brake Control Module

The GMC Sierra’s trailer brake control module is an important part of towing safety. When towing a trailer, the module helps to apply the brakes on the trailer in proportion to how much the truck is braking. This can help prevent accidents by keeping the trailer from becoming “out of control.”

If you have a 2015 GMC Sierra and are planning on doing any towing, it’s important to know where your truck’s trailer brake control module is located. The module is usually found mounted on the firewall near the brake pedal assembly. It’s important to consult your truck’s owner manual for specific instructions on finding and accessing the module.

Once you’ve located the module, you’ll need to connect it to the proper wiring harness before you can start using it. Consult your owner manual or a professional mechanic for help with this step. Once everything is properly connected, you should be all set to use your trailer brake control module whenever you need it!

Service Trailer Brake System 2015 Silverado No Trailer

If your 2015 Chevy Silverado doesn’t have a trailer brake system, don’t worry – you’re not alone. Many Silverado owners find that their trucks don’t come equipped with this feature, and it can be a real pain when trying to tow a trailer. There are a few different ways to add a trailer brake system to your Silverado, and we’ve outlined them all for you below.

The first option is to install an aftermarket trailer brake system. This is probably the easiest way to go, as there are many kits available that will fit your truck perfectly. You’ll just need to follow the instructions included in the kit, and you should be good to go.

If you’re not comfortable installing the brake system yourself, you can always take it to a professional mechanic or dealership and have them do it for you. Another option is to retrofit your existing braking system. This will require some work on your part, but it’s definitely doable if you’re handy with tools.

You’ll need to find a compatible master cylinder and proportioning valve for your Silverado, and then install them according to the instructions provided by the manufacturer. This option will likely cost more than buying an aftermarket kit, but it’ll be worth it if you want a OEM-grade installation. Finally, you could always just buy a new truck that comes equipped with a factory-installed trailer brake system.

If money isn’t an issue, this is probably the best route to take – but it’s important to note that not all Silverados come with this feature (even though most newer model years do). So if you’re dead set on having a truck with a trailer brake system, make sure to do your research before making any purchase decisions. We hope this article has helped clear up some of the confusion surrounding adding a trailer brake system to a 2015 Chevy Silverado.
