GM Trailer Brake Control Module (TBCM) — part number 85073616, programmed to your VIN and ready to install. GM lists this part as programming required; a blank or used module will not run the trailer brake output until it is set up for your vehicle.
This module drives the electric brake output for the factory integrated trailer brake controller (RPO JL1). Typical symptoms: "Service Trailer Brake System" message, no trailer brake output, or trailer brake DTCs that follow the module.
