Simple 2013, Sierra Trailer Brake Controller Wiring Diagram Collections - Look into wiring for shorts between trailer brake (electric powered brake) twine (blue) and any/all the following trailer wires: proper turn/brake, left flip/brake, walking lighting, returned up, battery, ground. Please observe that even warmness shrunk splices are not always water tight. To request me you may put for hal only, in the first line of the query. This way i need to get it. If you want extra guidance on this subject just preserve replying to this question so all of the info is on one query touching on this trailer brake problem.
Do you think ? I'm suspecting the controller itself . I'm going to go through the checking out day after today .... See if i will locate wiring difficulty .... Is there a way to test the brake strain sensor or use an ohm meter to look if contacts are remaining when strolling? Permit me recognize what you think. Gm is receiving some of again trailer brake manipulate modules (tbcm) and trailer brake relays which can be completely functional. The tbcm monitors the voltage of the electrical brake twine (darkish blue circuit forty seven) that runs from the trailer brake relay to the 7-pin trailer connector inside the bumper. If the voltage on this cord is shorted decrease or higher than the designed output voltage of the relay the tbcm will set a dtc.
I'm going to provide you with the twine diagram. This must assist provide you with an concept of how the device is hooked up so that you can do some checks. With your information of electrical systems , this must be a benefit to you. The wiring concerns i've located were corrosion problems near where the harness connects to the tbcm and wherein people have spliced in for fifth wheel hitches. We get sodium chloride placed on our roads within the wintry weather and it surely impacts connections if they may be made poorly. Look at the complete legnth of the cord from front to lower back. Pull the inner fender on the left aspect the front to check out the harness. There are a few sharp edges which can cut into the bottom of the harness and cannot be seen from the pinnacle.
