Description:

This error code indicates that the Cab Load Center (CLC) switched supply voltage exceeds 15.5 V while the engine speed is above 512 rpm. Elevated voltage levels can suggest issues such as a malfunctioning alternator or incorrect regulator settings, which may lead to potential damage to electronic components or erratic system behavior.

Reaction:

The system may limit or disable certain functions to prevent damage to sensitive electronic components due to high voltage.

Recommendations:

• Check Voltage Regulator and Alternator: Ensure that the alternator and voltage regulator are functioning correctly and are not overcharging the electrical system.
• Inspect Wiring and Connections: Look for any damaged wires or loose connections that might be causing irregular voltage levels.
• Monitor Voltage Levels: Regularly monitor the CLC voltage levels, especially under varying engine speeds, to ensure they remain within specified limits.
• Consult Technical Support: If the above steps do not resolve the issue, it may be advisable to consult John Deere technical support for further diagnostics.

Note:

Maintaining proper voltage levels is critical for the safety and functionality of electronic systems in heavy machinery. Regular checks and maintenance can prevent issues associated with high voltage conditions.
