Yes, it is often possible to add a factory trailer brake controller to a 2014 Chevrolet Silverado, even if it wasn’t originally equipped. However, the process involves specific parts, dealer programming, and a bit of technical know-how to ensure proper functionality and safety.
Understanding Trailer Brake Controllers and the 2014 Silverado
Towing a trailer requires more than just a hitch. For heavier loads, trailer brakes are essential, and a trailer brake controller is the device that allows the driver to proportionally apply those brakes from inside the cabin. The 2014 Silverado offered a factory-installed trailer brake controller as an option. If your truck didn’t come with it, don’t despair. Retrofitting is a viable alternative.
The Importance of a Properly Functioning Trailer Brake Controller
A properly functioning trailer brake controller is paramount for safe towing. It allows for synchronized braking between the tow vehicle and the trailer, preventing trailer sway, reducing stopping distances, and ultimately improving safety for you and other drivers on the road. Without a functioning trailer brake controller, the trailer’s momentum can push the tow vehicle, potentially leading to loss of control, especially in emergency braking situations.
Retrofitting a Factory Trailer Brake Controller
The process of adding a factory trailer brake controller to a 2014 Silverado involves several steps:
- Acquiring the Necessary Parts: This includes the trailer brake controller module itself, the appropriate wiring harness, and the dash trim panel with the integrated control buttons.
- Physical Installation: The controller module is typically mounted inside the dashboard, often near the steering column. The wiring harness needs to be connected to the truck’s electrical system, including the brake light switch signal.
- Programming the Truck’s Computer: This is arguably the most crucial step. The truck’s Body Control Module (BCM) needs to be reprogrammed to recognize and communicate with the newly installed trailer brake controller. This typically requires a visit to a Chevrolet dealer or a qualified mechanic with access to the necessary diagnostic tools and software.
Ensuring Compatibility and Proper Functionality
Not all aftermarket solutions are created equal. While universal trailer brake controllers are available, integrating the factory unit offers a seamless experience, utilizing the truck’s existing wiring and computer systems. This integration often provides features like trailer sway control, which relies on the truck’s sensors to detect and mitigate trailer sway by selectively applying trailer brakes. Improper installation or programming can lead to malfunctions, including brake failure, which is why professional installation and programming are highly recommended.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions regarding adding a factory trailer brake controller to a 2014 Silverado:
1. Where is the factory trailer brake controller located on a 2014 Silverado?
The factory trailer brake controller, when installed, is integrated into the lower left portion of the dashboard, near the steering column. The control buttons, which allow you to adjust the gain (braking force) and manually apply the trailer brakes, are located on the dash trim panel.
2. Can I install the trailer brake controller myself?
While some mechanically inclined individuals may attempt the installation, it’s highly recommended to have it professionally installed. The wiring can be complex, and the programming requires specialized equipment. Incorrect wiring could damage your truck’s electrical system, and improper programming can render the controller useless or even dangerous.
3. What is the approximate cost of adding a factory trailer brake controller to a 2014 Silverado?
The cost can vary depending on the source of the parts and the labor rates of the installer. Expect to pay anywhere from $400 to $800 or more for parts and labor. The dealer is generally more expensive than an independent shop that specializes in truck accessories and electronics.
4. Will adding a trailer brake controller void my truck’s warranty?
Adding a factory trailer brake controller, when done correctly using genuine GM parts, should not void your truck’s warranty. However, if the installation is done improperly and causes damage to the truck’s electrical system, it could potentially void the warranty on those specific components.
5. What is gain on a trailer brake controller?
Gain refers to the amount of braking force applied to the trailer brakes in relation to the tow vehicle’s braking. Adjusting the gain allows you to synchronize the braking between the truck and the trailer. Too little gain and the trailer won’t brake effectively; too much gain and the trailer brakes will lock up.
6. How do I adjust the gain on my trailer brake controller?
The gain is adjusted using the buttons on the dash trim panel. The goal is to set the gain so that the trailer brakes engage smoothly and proportionally with the truck’s brakes. The ideal setting depends on the weight of the trailer and the road conditions.
7. What tools are required for the installation?
The installation typically requires basic hand tools such as sockets, wrenches, screwdrivers, and wire strippers. A multimeter can be helpful for testing wiring connections. However, the most important tool is access to the GM Tech2 diagnostic tool or equivalent for programming the BCM.
8. Can I use an aftermarket trailer brake controller instead of the factory one?
Yes, aftermarket trailer brake controllers are a viable alternative. However, they may not integrate as seamlessly with the truck’s systems and may not offer features like trailer sway control. Installation of an aftermarket controller is generally simpler, but it might require splicing into the truck’s wiring.
9. What are the symptoms of a malfunctioning trailer brake controller?
Symptoms of a malfunctioning trailer brake controller can include uneven braking, trailer sway, increased stopping distances, and a “Service Trailer Brake System” message on the dashboard.
10. Where can I find the wiring diagram for the trailer brake controller on a 2014 Silverado?
The wiring diagram can be found in the factory service manual for the 2014 Silverado. You can also find online resources, but it’s crucial to verify the accuracy of any diagram before using it.
11. Does my 2014 Silverado need a special wiring harness for the trailer brake controller?
Yes, you will need a specific wiring harness designed to connect the trailer brake controller module to the truck’s electrical system. This harness is often included with the trailer brake controller kit.
12. What should I do if I get a “Service Trailer Brake System” message after installing the controller?
A “Service Trailer Brake System” message indicates a problem with the trailer brake controller system. Check all wiring connections, ensure the trailer brake wiring is properly connected, and re-check the programming of the BCM. If the problem persists, consult a qualified mechanic or Chevrolet dealer.
Conclusion
Adding a factory trailer brake controller to your 2014 Silverado is a worthwhile upgrade for those who frequently tow. While the process requires specific parts and programming, the improved safety and control offered by a properly functioning trailer brake controller make it a worthwhile investment. Always prioritize safety and seek professional assistance when needed to ensure a successful and reliable installation.
