Is Adapter Needed to Use Carlisle HydraStar Actuator with Factory Brake Control on 2014 Silverado


Recently I pulled a trailer with an HBA12. I liked it so much I decided to retrofit my trailer with the same type controller. I went with the HBA16 due to the brakes being Kodiak discs. I hooked everything up according to the wiring diagram and it is not recognizing the brakes. My truck is a 2014 Silverdao diesel. I checked the brake controller on my friends trailer and do no believe can not find an HBA CAM. If it is on the trailer it is well hidden. I went through all the troubleshooting tips and the HBA16 seems fine, as when hooking the wires up as recommended to troubleshoot all works as stated. Any suggestions as to what I may be doing wrong, or is it possible the HBA12 does not have comparability issues with the GM products? The brake controller built in worked flawlessly on the HBA12. Im a little perplexed as to what to do next... Please make suggestions. I did see the up to 2013 the compatibility chart shows needs the HBACAM but again not one on the HBA12 trailer. I even jumped a ground trailer to tow vehicle separately trying to see if it might be a ground issue but did not have any impact... Any suggestions again would be appreciated!

It is likely that the Carlisle HydraStar # HBA16 is not compatible with the factory integrated brake controller on your 2014 Chevy Silverado. Also, on controllers that are electric over hydraulic compatible they have to be in the electric over hydraulic mode for everything to work. Check to see if your integrated controller has that feature.

If the issue persists then you would need to use the adapter module, # HBA-CAM, to simulate regular electric trailer brakes so the integrated brake controller will work properly with the system.
