DTI 524215.04 – ISOBUS CAN+ Voltage Too Low

DTI 524215.04 (DTI )

Code: 524215.04



This diagnostic trouble code (DTC) indicates that the CAN+ voltage on the ISOBUS has fallen below 0.5 volts. Such low voltage is insufficient for normal data transmission, which can halt communication across the ISOBUS, affecting the coordination and functionality of connected systems and devices.


To prevent data corruption or loss, data transmission on the ISOBUS may be stopped, potentially leading to errors in system functionality or operational failures.


  • Inspect and Test Electrical System: Check for issues like poor connections, damaged wires, or faulty components that could be causing the voltage drop.
  • Measure Voltage Levels Regularly: Use a multimeter to monitor the CAN+ voltage levels to ensure they are within the normal operating range.
  • Enhance Electrical Connectivity: Ensure all connections are secure and improve grounding if necessary to stabilize voltage levels.


It is critical to maintain adequate voltage levels on the ISOBUS to ensure reliable and uninterrupted data communication. Regular electrical inspections and corrective measures are recommended to address any voltage issues promptly.
