Description:

This error code, XSC 003512.04, indicates that the voltage supply to the 5-volt components has dropped below 4.75 volts. This condition suggests a short to ground or an internal fault within the control unit, which can disrupt normal operation and damage the components.

Reaction:

When this fault occurs, the control software will exhibit limited or no functionality, affecting the overall operation of the vehicle’s electronic systems.

Recommendations:

Inspect Electrical Connections:

• Check the wiring and connectors associated with the 5-volt supply for any signs of damage, corrosion, or loose connections.
• Ensure that there are no shorts to ground.

Test Voltage Regulator:

• Verify that the voltage regulator responsible for maintaining the 5-volt supply is functioning correctly.
• Replace the voltage regulator if it is found to be faulty.

Monitor Voltage Levels:

• Use diagnostic tools to monitor the voltage levels of the 5-volt supply in real-time.
• Identify and correct any deviations from the normal operating range.

Consult Technical Support:

• If the issue persists, contact John Deere technical support for further diagnostics and solutions.
• Provide detailed logs of voltage readings and any steps already taken to address the fault.

Note:

Maintaining the correct voltage supply to electronic components is crucial for their reliable operation. Regular inspections and maintenance of the electrical system can help prevent such faults.
