Service Trailer Brake System GMC

Service Trailer Brake System

A “Service Trailer Brake System” error notice, as described in the 2015 GMC Sierra owner’s handbook, indicates a problem with the trailer brake module or wiring, preventing power from transferring to the trailer’s brakes.

You may continue driving with this error notice displayed, but you shouldn’t tow anything until it is corrected. You’ll need to take the trailer to the dealer for maintenance since third-party support for the factory-integrated trailer brake controller is limited.

Unfortunately, I cannot think of a method to turn off the warning.

Instead of using the factory-installed trailer brake controller, which may be costly to repair and troubleshoot, you should install an aftermarket brake controller to provide superior performance. The Redarc Tow-Pro Elite Trailer Brake Controller (SKU: RED44FR) is an excellent choice for this purpose.

The Tow-Pro Elite works like a factory trailer brake controller, with a hidden control box and an external knob fitted at the driver’s discretion. You may place it almost anywhere, and it will have a sleek, professional appearance. 

The Tow-Pro Elite is superior to the standard trailer brake controller since it allows you to convert between a proportional and a user-controlled mode. In addition, most factory-integrated trailer brake controllers don’t support electric over hydraulic trailer brakes; however, this one does.

Chevy Service Trailer Brake System 

Chevy service trailer brake system is a symptom of a fault impeding the power supply from the tow truck to the trailer with the wiring or module for the trailer’s brakes. You may notice a few additional symptoms besides the error message if this occurs.

Even when the service trailer brake error notice is shown, it is still possible to drive the vehicle. You are strongly encouraged to refrain from towing any weight until the issue has been resolved.

If you do not take action to remedy the problem, your brakes might sustain further damage over time, which could result in unanticipated accidents.

When you least anticipate it, even a little mistake might result in significant consequences, such as an accident. Therefore, it is in your best interest to address any problem you discover in your car until you are certain the issue has been resolved.

Therefore, even though it is feasible to drive with an error warning shown on the trailer brake controller, doing so is neither safe nor desirable.

At no point may safety be compromised in any way. Therefore, the fact that a vehicle continues to travel while having a problem does not always suggest that everything is OK.
