Description:

This error code indicates that the Selective Control Valve VI (SV VI) spool is overshooting its desired position. This can occur due to control system errors, hydraulic pressure issues, or mechanical problems with the valve.

Reaction:

When this error code is detected, the system will log the fault and may display a warning on the operator’s console. The precision of the valve operation may be compromised, potentially affecting equipment performance.

Recommendations:

Inspect Control Valve:

• Check the SV VI for mechanical issues that could cause overshooting, such as sticking or excessive play in the valve spool.

Check Hydraulic Pressure:

• Ensure that the hydraulic pressure is within the specified range and not causing the valve to move too quickly.

Calibrate Control System:

• Perform a calibration of the control system to ensure accurate positioning of the valve spool.

Update Software:

• Ensure that the control unit software is up-to-date with the latest versions provided by John Deere.

Consult Technical Support:

• If the issue persists after performing the above steps, consult John Deere technical support for further assistance.

Monitor System:

• After performing corrective actions, monitor the system to ensure the fault does not reoccur.

Note:

Proper calibration and regular maintenance are essential to prevent overshooting issues. Ensure that all control parameters are set correctly according to the manufacturer’s specifications.
