What Does the Chevy 2500 Service Trailer Brake System Warning Mean?
The Chevy 2500 service trailer brake system warning indicates that your truck has detected a fault in the trailer brake system. This can happen due to various reasons, including issues with the Electric Brake Control Module (EBCM), wiring between the truck and the trailer, or other related components.
When this warning appears, it signifies that the truck may not be able to properly manage the trailer brakes, which can be dangerous, especially during towing. It’s essential to diagnose and fix the issue as soon as possible.
Common Causes of Chevy 2500 Service Trailer Brake System Warning
Several potential factors can trigger the Chevy 2500 service trailer brake system warning. Below are the most common causes:
- Faulty Electric Brake Control Module (EBCM): The EBCM is the heart of the trailer brake system. A malfunction here can prevent the system from working correctly, leading to the warning message.
- Damaged or Corroded Wiring: The wiring between your Chevy 2500 and the trailer must be in good condition to transmit signals effectively. If the wiring is damaged, corroded, or loose, it can lead to a communication breakdown between the truck and trailer brakes.
- Blown Fuses or Relays: Fuses and relays play an important role in supplying power to the trailer brake system. If any fuse blows or a relay fails, the brake system may not function properly, leading to the warning.
- Faulty Brake Controller: The brake controller regulates the brake force applied to the trailer. If this controller malfunctions, it can trigger the service trailer brake system message.

- Inspect the Wiring
Start by examining the wiring between your truck and trailer. Check for any signs of corrosion, damage, or loose connections. Repair or replace any compromised wiring. - Test the Electric Brake Control Module (EBCM)
Use a diagnostic scanner to check for any error codes related to the EBCM. If the module is faulty, it may need to be reprogrammed or replaced to resolve the issue. - Check the Fuses and Relays
Locate the fuses and relays responsible for powering the trailer brake system. Replace any blown fuses or faulty relays to restore proper function. - Test the Brake Controller
Use the manual override feature on your brake controller to test the trailer brakes. If the brakes don’t engage properly, the controller may need recalibration or replacement.
