We've bypassed a couple of these with the CAN valve by replacing the factory PVED-CLS coil with a "dumb" CNH or John Deere ATR version, then run a new valve drive cable, AutoSense and (depending on model) a different manual override sensor, a power source for the lockout solenoid and then set it up as a random Case/NH non-guidance ready model (ignores the seat switch and Isolation valve messaging). The only drawback is the factory engage button on the armrest/joystick can no longer work, but definitely gets the tractor to steer properly. We had to do a Case Optum 270, and the owner loved it so much that he bought another new Optum 300 and made us bypass it before even trying the factory/CAN setup again.
