Buying a Replacement Trailer Brake Control Module For Your 2015 GMC Sierra

There are a few factors to consider before buying a replacement trailer brake control module for your 2015 GMC Sierra. These include location, cost, and reliability. If your truck is not factory installed, the brake controller could be the cause of your problems. To get the best replacement brake controller, you may consider getting one from the manufacturer. Alternatively, you can purchase an aftermarket trailer brake controller, but you should keep in mind that it may not be as good as the one from GM.

Location

If your truck has a trailer brake control module, you will need to know its location. This will be indicated on your truck’s DIC (driver information center). This module is a very complicated piece of equipment, but it is extremely important for your safety. There are a few things that you should do if you find that this part is not working properly. First, make sure that the trailer brake system is working properly.

If you receive the error message “Service Trailer Brake System,” the problem is most likely in the trailer brake control module or its wiring. This malfunction will prevent power from reaching the trailer brakes. As a result, towing is not recommended during this period. Since third party support for trailer brake control modules is limited, it is best to take your truck and trailer to a dealer for proper diagnosis and repair.

Cost

If you want to add trailer brakes to your 2015 GMC Sierra, you’ll need a trailer brake control module. This component controls the trailer’s brake system, and helps it apply or release pressure when necessary. It comes with an OEM-style interface and is compatible with trailers with two to eight brakes and one to four axles. It also features plug-and-play wiring and tri-color LEDs.

The module connects to the trailer’s wiring system and has a power button. It also needs a fuse, so you should replace it if it burns out. To test the controller, connect a multimeter to the blue wire connected to the trailer connector. When testing the voltage, make sure the device is working properly. If it isn’t, call a mechanic to install it.

Problems

A 2015 GMC Sierra has a known trailer brake control problem. The unit is located just above the spare tire under the bed of the truck. It costs $695 to replace. While the problem has been reported to GM, the company hasn’t done much to address it. They’ve issued no recall notices and haven’t offered any solutions to the problem.

The trailer brake system light is constantly on and off. The warning beep sounds every thirty seconds. It goes off after the truck stops moving, but it happens at all speeds.

Reliability

If you own a 2015 GMC Sierra, you may be wondering about the reliability of the trailer brake control module. This device is integrated with the brake system in your vehicle and can cause an “error message” if it malfunctions. The “error message” indicates a problem with the trailer brake control module or wiring, and it prevents power from being sent to the trailer brakes. While this error message is usually harmless, towing is not recommended while the error message is displayed. Third-party support for factory-integrated trailer brake controllers is limited, and it may require you to take your vehicle to a dealer for repair.

The exact mounting location of the trailer brake control module can vary by trim and configuration, so check your owner's manual or ask a dealer to confirm it on your specific truck. The module controls how many brakes are released at once, and depending on the vehicle, it may stop working altogether. This is most likely to happen when the trailer is loaded beyond its rated weight, since an overloaded trailer can cause the brake control module to function improperly and increase rollover risk.

Maintenance

If you’re concerned about your vehicle’s brake performance, you might need to get your trailer brake control module checked. A malfunction in this electronic device can affect traction control systems, so maintenance is essential. Fortunately, this procedure is relatively simple, and you don’t have to jack up the vehicle. However, if you’re unfamiliar with electrical work, it’s best to leave it to an ASE-certified mechanic.

If you notice that your trailer brake light is flashing or not working, it might be time to check the module. Usually, the malfunction is caused by a disconnection in the wiring. Moreover, if the module is not functioning properly, you may be at risk of a vehicle accident. Fortunately, you can repair this problem by recalibrating the electronic brake control module.
