Description:

This error code indicates that the Selective Control Valve Unit VII (SV VII) is not receiving the required messages from the SCC (Selective Control Component). This lack of communication can disrupt the normal operation of the valve unit.

Reaction:

When this error code is detected, the functionality of the Selective Control Valve Unit VII may be impaired, potentially leading to hydraulic control issues.

Recommendations:

Inspect Communication Lines:

• Check the communication lines between the SCC and SV VII for any signs of damage, loose connections, or interference. Repair or replace any faulty components.

Verify SCC Operation:

• Ensure that the SCC is functioning correctly and sending the necessary messages to SV VII. Perform diagnostics on the SCC to check for any faults.

Software Updates:

• Ensure that the software for both SCC and SV VII is up-to-date. Update to the latest versions if necessary.

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:

Maintaining proper communication between control units is crucial for the efficient operation of the equipment. Regular inspections and updates can help prevent communication-related issues.
