Description:

This error code is generated if the control software detects that the current on the CAN BUS is too high, indicating a short circuit 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 Bus for signs of damage, loose connections, or corrosion. Repair or replace any faulty components.

Test Current Levels:

• Use a multimeter to measure the current on the CAN Bus. Ensure it remains within the specified range. If it is too high, investigate the power source for faults.

Check for Shorts:

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

Verify Terminating Resistor:

• Ensure that the terminating resistor is correctly installed and functioning properly. Replace if necessary.

Update Control Software:

• Ensure that the control software is updated to the latest version. Firmware updates might improve handling of CAN Bus current 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 Bus current remains within the specified range and the error does not recur.

Note:

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