Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Trailer Brake Control Module Programming and Setup
If the Trailer Brake Control Module or the combination Fuel Pump/Trailer Brake Control Module is replaced or needs to be reprogrammed, refer to Service Programming System (SPS) . The calibrations for either of these modules are accessed through the FPCM Fuel Pump Control Module selection in the supported controllers list. The Trailer Brake Control Module is not listed as a separate choice. Once the Fuel Pump Control Module is selected, the SPS system will download the proper calibration for the vehicle based on the VIN entered.
