RLC 002240.09 – Incorrect CAN Bus Message, Information from TEC Control Software

RLC 002240.09 (RLC 2240.09)

Code: 002240.09

Shortcode: 2240.09


This diagnostic trouble code is generated if a data transfer problem occurs between the TEC control software and the RLC control software. The reception of one, several, or all of the CAN messages transmitted by the TEC control software is intermittent or non-existent, possibly due to a loose wire. This indicates a problem in the CAN bus or the transmitting control software.


When this error is detected, the control software may experience limited or no functionality, affecting the performance or operation of specific electronic control systems within the equipment.


  • Inspect CAN Bus Connections:
    • Check all CAN bus connections between the TEC and RLC control software for signs of damage, loose connections, or corrosion. Secure or replace any compromised connectors.
  • Test CAN Bus Network:
    • Use a CAN bus analyzer to test the network for intermittent connections or data transfer issues. Identify and resolve any faults found during the analysis.
  • Verify Wiring Integrity:
    • Inspect the wiring harness for any signs of wear, damage, or corrosion. Repair or replace any compromised wiring.
  • Check for Electrical Interference:
    • Ensure there are no sources of electrical interference near the CAN bus network that could be causing communication errors.
  • Update Control Software:
    • Make sure both the TEC and RLC control software are updated to the latest versions to address any potential issues with CAN message processing.


Consistent communication between the TEC and RLC control software is crucial for the reliable operation of the equipment. Prompt diagnosis and resolution of CAN bus issues are essential to maintain system functionality.
