Why are the trailer brakes not working on a 2024 Chevy 2500?

Troubleshooting Trailer Brakes on a 2024 Chevy 2500
If the trailer brakes on your 2024 Chevy 2500 are not working, there are several potential causes and troubleshooting steps to consider. Here’s a breakdown of possible reasons and solutions based on the information available:
1. Trailer Brake Control Module Issue:
The Trailer Brake Control Module in certain 2023 and 2024 GM models may become disabled while pulling a trailer due to a peculiar interaction between the vehicle’s battery and the trailer’s battery. This can result in a “Service Trailer Brake System” message on the Driver Information Center.
2. Two-Way Communication and Charging:
The brake controller in the truck monitors the battery voltage in the trailer and charges it. It’s suggested that there must be two-way communication of some sort between the truck and the trailer.
3. Potential Technical Bulletin:
A technical bulletin from GM addresses the issue of trailer brakes becoming disabled, and it mentions that this condition may be caused by the solar panel battery charger or generator on the customer’s trailer.
4. Troubleshooting Process:
Discovering why the trailer brakes are not getting power will be a process of elimination. It’s important to check all systems and connections thoroughly, including the trailer brake control module, battery voltages, and potential two-way communication between the truck and the trailer.
5. Potential Solutions:
– It’s suggested to check the junction box where the cord for the trailer connects to the truck wiring, as a bad connection in this area could affect the trailer brakes.
– Some users have reported that using an in-line Echo brake controller resolved the issue with the integrated brake controller not activating the brakes on certain trailers.
It’s important to note that if your vehicle is under warranty, it’s advisable to ask for it to be covered and/or call Chevrolet/GMC Customer Service for assistance. Additionally, if the issue persists, it may be beneficial to consult with a certified technician or dealership for further diagnosis and resolution.
If you have already checked these potential causes and solutions, and the issue still persists, it may be necessary to seek professional assistance to diagnose and resolve the problem effectively.
