Description:

The error code VTi 523774.04 indicates that the voltage at the CAN- lead (vehicle CAN BUS) is too low. This can result from issues such as a weak power supply, faulty CAN BUS wiring, or connection problems. 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:

Check Power Supply:

• Ensure that the power supply to the CAN BUS system is stable and providing adequate voltage.
• Inspect power connections for any signs of damage or corrosion.

Examine CAN BUS Wiring:

• Inspect all CAN BUS wiring for signs of wear, damage, or loose 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 low voltage readings.

Inspect Voltage Regulator:

• Verify that the voltage regulator is functioning correctly and maintaining the correct voltage levels.
• Replace the voltage regulator if it is found to be faulty.

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 low voltage issues promptly helps prevent communication failures and system malfunctions.
