Description:

This error code indicates that the voltage of the CAN- lead is too low, suggesting a short to ground.

Reaction:

The control software may function in a limited capacity or not at all, affecting CAN Bus communication and overall vehicle operation.

Recommendations:

Inspect CAN Bus – Connections:

• Check the wiring and connections of the CAN- lead for signs of damage, loose connections, or corrosion. Repair or replace any faulty components.

Test Voltage Levels:

• Use a multimeter to measure the voltage of the CAN- lead. Ensure it remains within the specified range. If it is too low, investigate the power source for faults.

Check for Shorts:

• Inspect for any short circuits to ground along the CAN- wiring. Repair any identified shorts.

Update Control Software:

• Ensure that the control software is updated to the latest version. Firmware updates might include improvements in handling CAN Bus voltage levels.

Consult Manufacturer Support:

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

Monitor System Performance:

• After addressing the issue, monitor the system to ensure the CAN- voltage remains within the specified range and the error does not recur.

Note:

Maintaining proper voltage levels in the CAN Bus is crucial for reliable communication. Regular checks and maintenance can prevent voltage-related issues.
