I installed the EOH module, then when I hooked to the 5th wheel to have new tires installed, no brakes at all....the actuator/pump would work.......called the company who installed the disc brakes and did their trouble shooting suggestions, and they said a bad solenoid in the pump and sent a replacement. I took the 5th wheel and truck to a nearby shop whio builds trailers to have them change it out....long story short, voltage leaving the truck, still wouldnt work, they brought out their tester and the actuator/pump worked like it should. They installed a Dexter magnet, un hooked the EOH module, and the only way the actuator/pump would work off the truck was to switch it back to electric brakes.
Took the truck to the dealer, and they said it showed codes, on the brake system, cleared them and re programmed it...btw, the first recall I got on the truck was for the trailer braking system. I havent changed it to elec or hyd and tried it yet....BUT just wondering if plugging in the camper while the truck was running could have caused the error codes from a arc or something.
