Description:

This error code is triggered when the supply voltage (ELX) to the control software exceeds 15.5 volts while the engine speed is above 500 rpm. Such high voltage levels can indicate an issue with the voltage regulation system or an overcharging condition from the alternator.

Reaction:

When this error is detected, the control software may experience limited or no functionality. This can lead to reduced performance or failure of specific electronic control systems within the equipment.

Recommendations:

• Inspect the Charging System:
  • Verify the alternator’s output voltage. Ensure it is within the specified range. If the alternator is overcharging, it may need repair or replacement.
• Check Voltage Regulator:
  • Examine the voltage regulator for proper operation. A faulty regulator can cause voltage levels to rise above acceptable limits. Replace if necessary.
• Inspect Battery Connections:
  • Ensure all battery terminals and connections are clean, secure, and free from corrosion. Poor connections can affect voltage regulation.
• Examine Wiring and Connectors:
  • Inspect the wiring harness and connectors associated with the control software and power supply. Look for any signs of wear, damage, or corrosion. Repair or replace any compromised wiring or connectors.
• Monitor Engine RPM and Load:
  • Verify that the engine speed is consistent and within the normal operating range. Unusual RPM fluctuations can affect voltage levels.
• Update Control Software:
  • Ensure that the control software is up-to-date with the latest firmware. Software updates can include fixes for voltage handling and other related issues.

Note:

High supply voltage can lead to damage of sensitive electronic components over time. Regular maintenance of the electrical system, including battery and alternator checks, is essential to prevent such issues. If this error code appears frequently, it is crucial to address the root cause promptly to avoid long-term damage to the equipment’s control systems.
