Description:

This error code indicates that the Selective Control Valve Unit V (SV V) is not receiving the required messages from the SCC (Selective Control Coordinator). This communication failure can be due to issues in the CAN bus network, wiring problems, or faults within the control units.

Reaction:

When this error is detected, the equipment may experience loss of control or functionality related to the Selective Control Valve Unit V. This can lead to operational inefficiencies and potential safety issues.

Recommendations:

Check Communication Network:

• Inspect CAN Bus Connections: Ensure all CAN bus connections are secure and free from damage. Look for loose or corroded connectors and repair or replace them as necessary.
• Test CAN Bus Integrity: Use diagnostic tools to test the integrity of the CAN bus network. Look for any breaks, shorts, or excessive resistance in the wiring.

Verify Control Unit Functionality:

• Check SCC and SV V: Ensure both the SCC and SV V units are functioning properly. Test for any internal faults or failures and replace units if necessary.
• Update Firmware: Make sure the firmware for both SCC and SV V is up-to-date to ensure proper communication and functionality.

Perform VLC Code Diagnostics:

• Associated Codes: Check for any related codes in the Vehicle Load Center (VLC) control unit, as issues here can affect communication with the SCC and SV V.
• Diagnostic Tools: Utilize John Deere specific diagnostic tools to read and clear VLC-related codes.

Monitor System After Repairs:

• Continuous Monitoring: After repairs, monitor the system to ensure the communication between SCC and SV V is restored and stable.
• Record Observations: Document any anomalies or recurring issues for further troubleshooting if needed.

Note:

Communication issues can often be complex and may require a thorough inspection of the entire control and communication system. Ensure that all related components and wiring are regularly maintained to prevent future issues.
