Best 2007, Sierra Trailer Brake Wiring Diagram Galleries - Some clients may additionally remark of a service trailer brake message on the dic and one or greater of the subsequent dtc's: c1115, c1116, c1117, c1118. This concern can be very intermittent and might occur with or without a trailer linked to the truck. For the duration of a recent warranty overview of lower back trailer brake manage switches all switches had been located to be ntf (no problem observed). I wish gm had a system description that might list the operation in info that technicians want to diagnose these systems. Sadly, as i mentioned before, data may be very restricted, and a test device is needed for diagnostics.

€? if the voltage is better, the up to date calibration will help. Reprogram the tbcm with the cutting-edge cals in tis2web.?? if the voltage is lower, then the updated calibration need to nevertheless be installed, but additional diagnostics can be needed to accurate the concern. Please follow the below statistics and suitable si diagnostics for additional help. Do the analysis tomorrow and lets see what the consequences are after that. We will think this problem to loss of life, and all the possibilities. But until we affirm the circuits, all we're doing is guessing.

The wiring concerns i have determined were corrosion issues close to where the harness connects to the tbcm and where people have spliced in for fifth wheel hitches. We get sodium chloride put on our roads within the iciness and it surely affects connections if they're made poorly. Check out the whole legnth of the cord from the front to lower back. Pull the inner fender at the left aspect front to look at the harness. There are a few sharp edges which can reduce into the lowest of the harness and can not be visible from the pinnacle. Do you observed ? I'm suspecting the controller itself . I'm going to undergo the checking out tomorrow .... See if i will discover wiring difficulty .... Is there a manner to check the brake stress sensor or use an ohm meter to peer if contacts are last while strolling? Allow me know what you watched.
