Troubleshooting Genesis Brake Controller that Reads 99 instead of 40 When Braking


Whats the problem and how-to fix


Expert Reply:

Have you tried adjusting the gain of the controller down to 40? You probably already tried that but I figured I would at least mention it. What is the angle of the controller? It has to be installed in the range of angles that you see in the attached picture to work properly.

Does the controller immediately read 99 when you touch the brakes? That would indicate a short on the brake output circuit most likely to a stoplight circuit. You would need to go over the wiring of the connectors on the truck and trailer. I also attached a couple help articles on troubleshooting for you to check out as well.
