The 2019 Chevrolet Silverado's Trailering app provides useful towing information, but connectivity issues can prevent it from communicating with compatible trailers. Understanding the system helps restore functionality.
How the Trailering System Works
The Trailering app interfaces with the truck's towing systems and, when equipped with a compatible trailer sensor, provides tire pressure, temperature, and other trailer data directly in the truck's display.
Common Connectivity Problems
Trailer Module Not Detected
The truck must recognize a compatible trailer module through the 7-pin connector. Wiring issues, corroded pins, or incompatible modules prevent detection.
Bluetooth Pairing Failures
Trailer tire pressure sensors use Bluetooth to communicate with truck-mounted receivers. Pairing issues or interference can disrupt communication.
App Software Glitches
The infotainment system app can become corrupted or outdated. Software updates often resolve unexplained connectivity failures.
Trailer Wiring Problems
The data communication wire in the 7-pin connector must be properly connected. Many aftermarket wiring harnesses don't include this dedicated data circuit.
Setting Up Trailer Profiles
The system allows multiple trailer profiles with different tire pressure specifications. Ensure profiles are correctly configured for accurate warnings.
