If you have a trailer brake system light that keeps coming on, there are a few possible reasons why. One reason could be that the brake fluid level is low. Another possibility is that there is an issue with the wiring, such as a loose connection.

Turn off Service Trailer Brake System
If you have a Service Trailer Brake System (STBS) on your vehicle, you may be wondering how to turn it off. Here are some instructions on how to do so:
First, locate the STBS switch.
It is usually located near the brake pedal or in the center console. Once you have found the switch, flip it to the “off” position.
Now that the STBS is turned off, you will no longer have enhanced braking power when hauling a trailer.
If you need to use your trailer brakes, you will need to engage them manually by pulling on the trailer’s brake lever.
Why Does My Truck Keep Saying Trailer Brake System?
If your truck keeps saying “trailer brake system,” there could be a few different issues at play. First, it’s important to make sure that your trailer is properly connected to your truck. If the connection is loose or broken, that could be why your truck is giving you the error message.
Another possibility is that there could be an issue with the wiring between your truck and trailer. If the wires are damaged or corroded, they may not be able to carry the electrical signal from your truck to the trailer brakes properly. This can cause the error message to appear on your dashboard.
Finally, it’s possible that there is a problem with the actual trailer brakes themselves. If they’re not functioning properly, they may not be able to engage when you hit the brake pedal in your truck. This can also cause the “trailer brake system” error message to appear.
If you’re having trouble troubleshooting the issue yourself, it’s best to take your truck and trailer to a qualified mechanic or dealership for assistance. They’ll be able to diagnose and fix the problem quickly so you can get back on the road safely.
How Do You Reset a Trailer Brake Controller?
If your trailer brake controller isn’t working properly, you may need to reset it. To do this, first make sure that the vehicle’s ignition is off and the trailer is disconnected. Next, locate the fuse for the trailer brake controller and remove it.
Once the fuse is removed, press and hold the “Set” button on the controller for about 5 seconds. This will reset the controller back to its factory default settings. Finally, replace the fuse and reconnect the trailer.
Why Does My Gmc Sierra Keep Saying Trailer Brake System?
There are a few reasons that your GMC Sierra might be giving you the error message “trailer brake system.”
The first possibility is that there is an issue with the trailer’s wiring. If the trailer’s brakes are not receiving enough power, they will not be able to function properly.
Check the wiring between the truck and trailer to make sure all connections are secure and there is no damage to any of the wires.
If the wiring appears to be in good condition, then the problem may lie in the truck itself. The Sierra has a built-in Trailer Brake Controller (TBC) that helps regulate power to the trailer’s brakes.
If there is a problem with this controller, it could cause the trailer brakes to malfunction. Try resetting the TBC by disconnecting and reconnecting its power supply. If this does not fix the problem, then take your Sierra to a qualified mechanic or dealer for further diagnosis and repair.
How Do You Fix Service Trailer Brakes?
Assuming you are referring to service trailer brakes on a tow vehicle:
The first step is to check the owner’s manual to see if there are any special instructions for servicing the brakes on your particular model of vehicle. If not, the general procedure is as follows:
With the engine off, pump the brake pedal a few times to release any built-up pressure in the lines. Then hold the pedal down and loosen the bleeder screw on the caliper or wheel cylinder using a wrench. Be careful not to loosen too much – just enough so that fluid can escape when you depress the pedal.
Depress the brake pedal slowly and steadily until it reaches the floor; hold it there while fluid escapes from the bleeder screw. You may need someone else to do this part while you keep an eye on things at the caliper or wheel cylinder. When fluid stops flowing from the bleeder screw, close it up tightly and repeat this step until fresh fluid flows from the screw each time you open it.
Once you’ve bled all four brakes (or however many your vehicle has), top off The brake reservoir with fresh fluid and take your vehicle out for a test drive, being sure to go easy on The brakes until they have had a chance to “bed in” properly.
Conclusion
If you have a trailer brake system light that keeps coming on, there are a few things that could be causing the problem. One possibility is that the brakes are not adjusted properly. Another possibility is that the brake fluid level is low or there is a leak in the system.
If you suspect a leak, it’s important to have it repaired as soon as possible to avoid further damage to the system.
