SV6 004084.18 (SV6 4084.18)

Code: 004084.18

Shortcode: 4084.18

Description:

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

Reaction:

Inspect Control Valve:

  • Check the SV VI for mechanical issues that could cause undershooting, such as sticking or insufficient movement in the valve spool.

Check Hydraulic Pressure:

  • Ensure that the hydraulic pressure is adequate and within the specified range.

Calibrate Control System:

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

Set Flow Correctly:

  • If multiple valves are generating a 004084.18 code, refer to the “Determining Total Flow Demand” section in the Operator’s Manual to correctly set the flow.

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.

Recommendations:

Correct flow settings and regular calibration are crucial to prevent undershooting issues. Follow the manufacturer’s guidelines for maintenance and adjustments.
