DTI 002033.09 – CAN Bus Communication Error with BCU

DTI 002033.09 (DTI 2033.09)

Code: 002033.09

Shortcode: 2033.09

Description:

This diagnostic trouble code (DTC) indicates a communication failure between the Body Control Unit (BCU) and the DTI. The fault involves intermittent or nonexistent reception of CAN messages from the BCU, possibly due to issues like loose wiring or connection faults. This can affect the management of various body control functions, potentially leading to system inaccuracies or failures.

Reaction:

System instability or erratic operations may occur, with the DTI displaying warnings to notify the operator of the communication issue.

Recommendations:

  • Check and Secure Wiring: Ensure that the wiring and connections for the CAN bus system, especially those related to the BCU, are properly secured and undamaged.
  • Diagnose Communication Links: Use diagnostic tools to evaluate and troubleshoot the CAN bus and its components to restore reliable communication.
  • Verify BCU Operation: Make sure the BCU is functioning correctly and sending consistent, accurate data to the DTI.

Note:

Maintaining proper communication between the DTI and the BCU is essential for accurate body control and overall system functionality. Routine diagnostics and corrective maintenance are recommended to ensure system reliability.
