PL3 000158.04 – Supply Voltage (ELX) Too Low
PL3 000158.04 (PL3 158.04)
Code: 000158.04
Shortcode: 158.04
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.
