New Tow Vehicle
I just purchased a 2012 F-250 with the factory brake controller. When I hook up my 2007 Classis (with electric over hydraulic disc brakes) the brake pump cycles on and off every 4 seconds. I have set the electric over hydraulic mode in the P/U and have tried the electric only selection as well, no joy though, same thing. The brakes seem to work normally when the brake pedal is pushed, or the manual brake override it activated...but once the brakes are released, back to the cycling mode. I am unable to tow until I can figure it out. If anione is familiar with this, it would be great to get some ideas.
Thanks in Advance for your assistance,
