Symptom: New install on a Steer-Ready Versatile 4WD, can't get through calibrations and getting Valve Online Error on Steering Status screen.
Cause: Valve Type isn't set to Versatile. Also, the connectors on the factory cab pass-through harness can be seated either way, but only one way is correct. The Plus1 won't receive power if incorrect.
Resolution: Confirm Valve Type is set to Versatile. Check connections at the cab pass-through harness to confirm keys match up and that you have a green power indicator light come on the Plus1 controller.
