DTI 002023.09 – CAN Bus Communication Error with BIF

DTI 002023.09 (DTI 2023.09)

Code: 002023.09

Shortcode: 2023.09


This diagnostic trouble code (DTC) is issued when there is a data transfer problem between the Basic Interface (BIF) and the DTI over the CAN Bus network. The issue entails intermittent or nonexistent reception of one or more CAN messages from the BIF, potentially caused by loose wiring, poor connections, or signal interference. Such communication breakdowns can disrupt the basic interface functions, affecting data relays and system coordination.


The system may show erratic responses or operational delays, and the DTI may signal alerts to highlight the communication error.


  • Secure Wiring and Connections: Ensure that all connections and wiring between the BIF and DTI are secure and intact. Replace or repair any faulty elements.
  • Diagnose the CAN Bus System: Use diagnostic tools to analyze the network for errors or malfunctions that may impede communication.
  • Monitor BIF Functionality: Ensure that the BIF is properly functioning and capable of sending complete and accurate data.


Consistent and reliable communication via the CAN bus is essential for the smooth operation of the equipment. Routine maintenance and monitoring can help mitigate potential disruptions.
