Description:

This error code is triggered when the supply voltage (ELX) exceeds 16 volts. Excessive voltage levels can indicate an issue with the voltage regulator or an overcharging condition from the alternator.

Reaction:

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

Recommendations:

• Inspect the Voltage Regulator:
  • Check the voltage regulator for proper operation. A faulty regulator can cause voltage levels to rise above acceptable limits. Replace if necessary.
• Verify Alternator Output:
  • Measure the alternator’s output voltage to ensure it is within the specified range. Repair or replace the alternator if it is overcharging.
• Examine Battery Connections:
  • Ensure all battery terminals and connections are clean, secure, and free from corrosion. Poor connections can affect voltage regulation.
• Inspect 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.
• 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.
