Description:

This error code indicates that the switched supply voltage of the cab control unit is too low, suggesting a short to ground.

Reaction:

The control software may function in a limited capacity or not at all, affecting the operation of the cab control unit.

Recommendations:

Inspect Power Supply:

• Check the power supply for the cab control unit to ensure it is providing adequate voltage and not experiencing a drop.

Inspect Wiring and Connections:

• Inspect all wiring and connections for the cab control unit for signs of damage, loose connections, or corrosion. Repair or replace any faulty components.

Test Voltage Levels:

• Use a multimeter to measure the voltage at the supply lead. Ensure it does not drop below the specified voltage range. If it does, investigate the power source for faults.

Verify Ground Integrity:

• Ensure the ground connection is secure and free of corrosion. A poor ground can cause low voltage readings.

Replace Faulty Components:

• If any component is found to be causing the low voltage, replace it with a properly functioning unit.

Update Control Software:

• Ensure that the control software is updated to the latest version. Firmware updates might improve voltage regulation.

Consult Manufacturer Support:

• If the issue persists, consult technical support or the manufacturer for further diagnostics and assistance.

Monitor System Performance:

• After taking corrective actions, monitor the system to ensure the voltage remains within the specified range and the error does not recur.

Note:

Maintaining a stable power supply and proper connections is crucial for the reliable operation of the cab control unit.
