2010 GMC Sierra 2500 HD SLE 6.0L Trailer brake controls
Posted to GM Brakes on 3/28/2017 7 Replies

We are able to use the scanner to actuate trailer brakes for the duration of the 30 second allowed test cycle. No actuation from dash control or foot pedal application. Replaced module and relay with known good parts, no effect on problem.
