Troubleshooting Integrated Trailer Brake Controller 2020 GMC Sierra 3500 w/ Electric Over Hydraulic
Question:
I have a 2020 GMC Sierra 3500hd and I pull a 40’ gooseneck trailer with EOH brakes. I purchased the HBA-CAM hoping this would fix my issue of having no brakes and it still doesn’t work. But I can hook it up to my other truck and it works perfectly fine.

Expert Reply:
It sounds like you may have a programming issue with the factory controller on your 2020 GMC Sierra 3500HD. You will want to take your Sierra to your GMC dealer to have them verify the programming for the controller and add any updates which may be required.
The Hydrastar Electric Over Hydraulic Actuator Adapter Module # HBA-CAM is only designed to adapt the braking profile some integrated brake controllers have which only work on electric trailer brakes. While it does not appear your factory controller requires this adapter we always recommend using them since as the new controllers can receive updates from the dealer during a routine service which could change something and not allow the controller to work properly.
