PL1 000158.03 – Supply Voltage (ELX) Too High
PL1 000158.03 (PL1 158.03)
Code: 000158.03
Shortcode: 158.03
Description:
This diagnostic trouble code is generated when the control software detects a supply voltage (ELX) exceeding 16 V. This can occur due to overcharging from the alternator, issues with the voltage regulator, or wiring faults leading to excessive voltage supply.
Reaction:
When this error is detected, the equipment may enter a protective mode to prevent damage to electronic components. This could include reducing functionality or shutting down certain systems.
Recommendations:
- Inspect Alternator and Voltage Regulator:
- Check the alternator for overcharging issues.
- Verify the voltage regulator is functioning correctly and not allowing excessive voltage.
- Examine Wiring and Connections:
- Inspect wiring for any signs of damage, fraying, or poor connections.
- Ensure all connections are secure and free from corrosion.
- Check Battery Health:
- Test the battery for any faults or issues that could lead to abnormal voltage readings.
- Monitor System Voltage:
- Use a multimeter to monitor system voltage and ensure it stays within the normal range (typically 12-14 V).
Note:
High supply voltage can damage sensitive electronic components. Regular maintenance of the alternator and voltage regulator is crucial to prevent this issue.
