Vehicle is calibrated, but now won't auto-steer.

Symptom: Vehicle is calibrated, but now won't auto-steer.

Possible cause/resolution(s): 

1.  Power switch to ECU is not in the full forward position ("Auto" or "Steer").
2. No GPS on terminal: Go to GPS diagnostics and ensure DIFF age has between 1-8 seconds.
3. No job started: Start a new job, or continue an old one.
4. No AB line defined: Create AB straight, pivot, or contour to allow auto-steer guidance.
5. Filters not converged: This error is for eDriveX, XD, and XC only and can be found in the eDrive Status menu. If illuminated with a red exclamation mark, push on "Filter Converged" and read instructions on how to clear it. 
6. ECU and terminal needs reboot in proper sequence: Terminal first- wait until "accept" screen appears then turn on ECU to full forward position ("Auto" or "Steer").
