1. 1

   For the 'No Swath' condition (A-G-535): Verify that a valid swath/guidance line has been created and is actively selected in the AFS display menu.

2. 2

   For the 'Too Fast' condition (A-G-540 / AG-145): Verify the actual vehicle speed on the display. The system will lock out automatic steering or implement engagement if the speed exceeds the safety/operational threshold.

3. 3

   Check for related GNSS or speed mismatch codes that might indicate a sensor issue (e.g., A-G-555 - GNSS steering error or A-G-553 - Guidance speed mismatch).

1. 1

   Acknowledge error

   Acknowledge the error code on the AFS display.

2. 2

   Reduce speed

   If addressing 'Too Fast': Manually slow the vehicle down below the Autoguidance engagement threshold.

3. 3

   Select swath

   If addressing 'No Swath' (A-G-535): Navigate to the guidance menu on the display and record a new swath or select an existing valid guidance line.

4. 4

   Re-engage Autoguidance

   Re-engage the Autoguidance system once the speed is reduced and the swath is active.

5. 5

   Update software

   If the system still refuses to engage and throws unspecified errors, ensure that the latest software available on the Electronic Service Tool is loaded to the display and NAV controller.
