Description:

This error code indicates that the Selective Control Valve IV (SV IV) is not in the NEUTRAL position. This can be caused by mechanical issues, control lever movement with the key on and engine off, or electrical faults.

Reaction:

The equipment may not operate correctly, especially in functions that require the valve to be in a neutral position. A warning will appear on the control panel.

Recommendations:

• Inspect Valve Mechanism:
  • Check for any mechanical issues within the valve that could prevent it from returning to the neutral position.
• Verify Electrical Connections:
  • Ensure all electrical connections to the SV IV are secure and free of corrosion or damage.
• Check Control Lever:
  • Avoid moving the control lever with the key on and the engine off, as this can cause the code.
• Update Software:
  • Ensure the control unit software is up-to-date to prevent any software-related issues.

Note:

Regular inspection and proper operation of the control lever can prevent this issue.
