Description:

This diagnostic trouble code is generated if the control software registers a supply voltage (ELX) of less than 9 V. This typically indicates an undervoltage condition in the electrical system, which could be due to issues such as a weak battery, faulty alternator, or poor electrical connections.

Reaction:

When this code is detected, the vehicle’s control systems may limit functionality to protect sensitive electronic components from insufficient power supply.

Recommendations:

Check Battery:

• Test the battery’s voltage and load capacity. Replace the battery if it is weak or failing.

Inspect Alternator:

• Verify the alternator is providing adequate voltage. Repair or replace the alternator if it is undercharging.

Examine Wiring and Connections:

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

Inspect Ground Connections:

• Ensure all ground connections are secure and free of corrosion.

Note:

Undervoltage conditions can affect vehicle performance and damage electronic systems. Promptly address any issues to maintain optimal functionality.
