Description:

This diagnostic trouble code is triggered when the system voltage (ELX) exceeds 15.5 volts for more than 5 seconds. This condition indicates that the electrical system is experiencing higher than normal voltage levels, which can be detrimental to various components.

Reaction:

When this code is detected, the equipment may enter a protective mode to prevent damage to electrical components. This can result in reduced performance or temporary shutdown of certain systems to safeguard the machine’s integrity.

Recommendations:

Inspect Voltage Regulator:

• Check the voltage regulator for proper operation. A faulty voltage regulator can cause over-voltage conditions. Replace if necessary.

Inspect Battery and Alternator:

• Ensure the battery is in good condition and properly charged.
• Check the alternator output to ensure it is not exceeding the specified voltage range. Replace or repair the alternator if it is malfunctioning.

Check Electrical Connections:

• Inspect all electrical connections for signs of corrosion, looseness, or damage. Ensure all connections are clean and secure.

Monitor and Record Voltage Levels:

• Use a multimeter to monitor the system voltage and record any anomalies. This can help in diagnosing intermittent issues.

Consult Technical Support:

• If the issue persists, consult technical support or the manufacturer for further assistance in diagnosing and resolving the problem.

Note:

High voltage conditions can lead to premature failure of electrical components such as sensors, control modules, and wiring. It is essential to address this issue promptly to avoid extensive damage. Additionally, extreme environmental conditions (e.g., high temperatures) can exacerbate voltage regulation issues. Regular maintenance and inspection of the electrical system can help prevent such problems.
