Description:

The error code VTi 523773.03 indicates that the voltage at the CAN+ lead (vehicle CAN BUS) is too high. This can occur due to issues such as a malfunctioning voltage regulator, faulty CAN BUS wiring, or interference from other electrical components. Proper voltage levels are essential for reliable communication over the CAN BUS.

Reaction:

When this error is detected, the equipment may experience communication failures or erratic behavior in systems that rely on CAN BUS data. This can affect the performance and coordination of various vehicle systems.

Recommendations:

Inspect Voltage Regulator:

• Check the voltage regulator for proper operation and ensure it is not allowing excessive voltage.
• Replace the voltage regulator if it is found to be faulty.

Examine CAN BUS Wiring:

• Inspect all CAN BUS wiring for signs of wear, damage, or improper connections.
• Ensure all connections are secure and free from corrosion.

Test CAN BUS Components:

• Use diagnostic tools to test the voltage levels on the CAN+ lead.
• Identify and replace any components that are causing high voltage readings.

Check for Electrical Interference:

• Ensure that no other electrical components are introducing interference or excessive voltage into the CAN BUS.
• Shield or reroute wiring as necessary to prevent interference.

Consult Technical Support:

• If the issue persists, contact technical support or the manufacturer for further guidance.
• They may provide additional diagnostic procedures or suggest specific parts to replace.

Note:

Regular maintenance of the CAN BUS system, including checking voltage levels and ensuring proper wiring, is crucial for reliable communication. Addressing high voltage issues promptly helps prevent communication failures and system malfunctions.
