  • Fixed my code.
For the past year and a half I’ve been getting a trailer brake service warning on my truck. This was able to fully resolve the code and remove the warning for me. Super easy installation. Once I drop the spare tire, there were only four bolts holding the whole entire sensor and sensor covered on. Installation took me about 15 minutes. Highly recommend. ... show more

  • Service Trailer Brake System - FIXED!
Fixed the annoying service trailer brake system alert on my 2014 Tahoe. No programming necessary, its pluck, chuck, and replace. But, getting to it is kind of a PITA.

  • Fixed my service trailer brake lights warning on my lmm.
Fixed my service trailer brake lights warning on my lmm. Just make sure your 30amp j fuse is good, should be the pink fuse at the end of the fuse box closest to the front of the vehicle.
