RLC 000444.04 – Control Software, Supply Voltage (BAT at Terminal J4) Too Low
RLC 000444.04 (RLC 444.04)
Code: 000444.04
Shortcode: 444.04
Description:
This error code is triggered when the supply voltage (BAT) at terminal J4 drops below 9 volts. Low voltage levels can indicate a failing battery, poor electrical connections, or issues with the charging system.
Reaction:
When this error is detected, the control software may experience limited or no functionality, affecting the performance or operation of specific electronic control systems within the equipment.
Recommendations:
- Check Battery Health:
- Test the battery to ensure it holds a charge and is in good condition. Replace the battery if it is old or unable to maintain adequate voltage.
- Inspect Electrical Connections:
- Inspect all electrical connections at terminal J4, including those at the battery and control software. Ensure they are clean, secure, and free from corrosion.
- Verify Charging System:
- Check the alternator and voltage regulator for proper operation. Ensure they are charging the battery correctly. Replace faulty components as necessary.
- Examine Wiring:
- Inspect the wiring harness for any signs of wear, damage, or corrosion. Repair or replace any compromised wiring.
Note:
Consistently low supply voltage can cause long-term damage to the control software and other electronic components. Regular maintenance of the electrical system is crucial to prevent such issues.
