Case IH A-G-120 - Display – Autoguidance System (AFS AccuGuide): No Swath is within 1/2 the Swath Width
Issue description
This is an operational error indicating that the vehicle is located in a pattern where guidance swaths cannot be generated because the vehicle is more than one-half of the swath width away from the selected swath.
Applies to these machines
9 machines- MAGNUM AFS Connect
- STEIGER AFS Connect
- Magnum
- Steiger
- long-wheelbase Puma
- Optum
- Axial-Flow 260
- AF series
- Patriot 50 series
Check the cause
Verify the physical location of the vehicle relative to the selected A-B line or swath to ensure it is not further than half the implement's swath width away
Determine if operating in a spiral pattern and check if the innermost swaths have been reached where software limits further generation
If operating on a curved swath, verify if the vehicle has been driven past the generated swath extensions
Repair steps
Manually steer closer to swath
For standard/straight swaths, manually steer the vehicle closer to the intended swath line until you are within half the swath width, then re-engage the autoguidance.
Create new straight pattern
For spiral patterns, if you are in the midst of the innermost swaths, create a new straight pattern for the innermost area of the field.
Drive tighter on curved swath
For curved swaths, if you have driven past the extensions, drive tighter/closer on the curved swath pattern to allow the system to pick up the guidance line again.
