Trailer Brake Control Module

The trailer brake control module in a 2013 Chevrolet Silverado is an essential component for safely towing trailers equipped with electric brakes. This module is responsible for coordinating the trailer's braking system with the truck's brakes, ensuring smooth and controlled stopping.

Location

The trailer brake control module in a 2013 Silverado is typically located in two possible areas:

1. Dashboard: The most common location is on the dashboard, to the left of the steering wheel, just above the 4WD mode dial. This placement allows for easy access and adjustment while driving.

2. Frame Rail: In some cases, particularly for aftermarket installations, the module may be mounted on the frame rail near the driver's side rear tire. This location is less common for factory-installed modules.

Identifying the Module

The trailer brake control module is usually a small, rectangular device with a digital display and adjustment buttons. If factory-installed, it will be seamlessly integrated into the dashboard. For frame-mounted modules, look for a black box with a multi-pin connector attached to it.

Installation and Wiring

For those installing an aftermarket brake controller, it's important to note the following:

  • The power supply for the brake controller is typically located in the engine compartment.
  • Look for a red wire taped between the fender well and the power junction box on the passenger side.
  • The wiring harness for the brake controller is often found under the dashboard, near the steering column.

Wiring Color Codes

When connecting the brake controller, use this color-coding guide:

  • Blue: Brake output to trailer
  • Red: 12+ volt power
  • White: Ground
  • White with blue stripe: Stop lights

Troubleshooting

If you're experiencing issues with your trailer brake control, such as blown fuses or error messages, consider these steps:

1. Check the fuse box for a blown trailer brake fuse.

2. Inspect the wiring harness for any damage or corrosion.

3. Ensure all connections are secure and free from debris.

4. If problems persist, the module itself may need replacement.

Remember, proper installation and maintenance of your trailer brake control module are crucial for safe towing. If you're unsure about any aspect of the installation or troubleshooting process, it's best to consult a professional mechanic or the vehicle's manual.
