Description:

This error code indicates that the Selective Control Valve VII (SV VII) spool is overshooting its desired position. This can occur due to issues with the control system or mechanical components of the valve.

Reaction:

When this error code is detected, the valve may not achieve the precise control needed for proper operation, leading to potential hydraulic performance issues.

Recommendations:

Inspect Control System:

• Check the control system and signals being sent to SV VII to ensure they are accurate and properly calibrated.

Inspect Valve Mechanism:

• Examine the mechanical components of SV VII for any signs of wear or damage that could cause overshooting. Repair or replace parts as necessary.

Software Calibration:

• Perform a software calibration of SV VII to ensure it is correctly configured to achieve the desired positions.

Consult Technical Support:

• Contact John Deere technical support if the issue persists after performing the above steps. They can provide further guidance and advanced diagnostic procedures.

Note:

Precision in valve control is crucial for optimal hydraulic performance. Regular calibration and maintenance can help prevent issues with overshooting.
