Description:

This error code is triggered when the supply voltage (ELX) drops below 11.2 volts with the engine speed below 500 rpm. This can indicate issues with the battery, electrical connections, or charging system under low engine load conditions.

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:

• Inspect Battery and Connections:
  • Test the battery to ensure it is in good condition and can hold a charge. Inspect all connections for security and cleanliness. Replace the battery if necessary and clean or tighten connections as needed.
• Check Charging System at Low RPM:
  • Verify the alternator and voltage regulator’s performance at low engine speeds. Ensure they are providing adequate charge to the battery. Replace faulty components if necessary.
• Examine Electrical Load:
  • Reduce unnecessary electrical loads when the engine is at low RPM to ensure sufficient voltage supply to critical systems.

Note:

Low supply voltage under low RPM conditions can impact the performance of electronic control systems. Regular checks and maintenance of the battery and charging system are essential to prevent such issues.
