Description:

This diagnostic trouble code (DTC) is activated when the CAN+ voltage on the ISOBUS exceeds 5.0 volts, indicating an overvoltage condition. This excessive voltage can disrupt data transmission across the ISOBUS, preventing the exchange of crucial operational data between connected devices and systems.

Reaction:

To prevent damage from overvoltage, data transmission on the ISOBUS may be halted, potentially leading to system errors or loss of functionality.

Recommendations:

• Inspect Electrical Components: Check for any malfunctions in the electrical system that could be causing voltage spikes, such as damaged wires or faulty connectors.
• Monitor Voltage Levels: Regularly measure the voltage levels within the ISOBUS to ensure they remain within safe parameters.
• Implement or Check Voltage Regulators: Verify the operation of voltage regulators designed to maintain stable voltage levels within the electrical system.

Note:

Maintaining proper voltage levels on the ISOBUS is crucial for reliable data communication and overall system health. Regular monitoring and maintenance are essential to prevent voltage-related issues.
