Description:

This diagnostic trouble code is generated if the control software registers a supply voltage (ELX) of more than 16 V. This typically indicates an overvoltage condition in the electrical system, which could be due to issues such as a faulty voltage regulator, alternator problems, or electrical short circuits.

Reaction:

When this code is detected, the vehicle’s control systems may limit functionality to protect sensitive electronic components from potential damage due to the high voltage.

Recommendations:

Inspect Voltage Regulator:

• Check the voltage regulator for proper operation. Replace if malfunctioning.

Check Alternator:

• Inspect the alternator output voltage to ensure it is within the specified range. Repair or replace the alternator if it is overcharging.

Examine Wiring and Connections:

• Inspect all relevant wiring and connections for signs of damage, wear, or corrosion that could cause an overvoltage condition. Repair or replace as necessary.

Battery Condition:

• Ensure the battery is in good condition and not causing fluctuations in voltage. Replace if necessary.

Note:

Overvoltage conditions can cause significant damage to electronic components. Address this issue promptly to avoid further damage.
