RLC 520426.07 – Transmitted CAN Bus Messages, High Error Rate

RLC 520426.07 (RLC )

Code: 520426.07



This diagnostic trouble code is generated if there is an excessive error rate with transmitted CAN bus messages. This indicates a problem with the CAN bus network, possibly due to electrical interference, faulty components, or network overload.


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 Network:
    • Perform a thorough inspection of the CAN bus network for any physical damage, loose connections, or corrosion. Repair or replace any compromised components.
  • Check for Electrical Interference:
    • Ensure that there are no sources of electrical interference near the CAN bus network that could be causing communication errors.
  • Verify Termination Resistors:
    • Ensure that proper termination resistors are installed at both ends of the CAN bus network. Incorrect termination can lead to high error rates.
  • Monitor CAN Bus Load:
    • Check the CAN bus load to ensure it is not overloaded. Reduce the number of devices on the CAN bus if necessary.
  • Update Control Software:
    • Make sure the control software is updated to the latest version to address any potential issues with CAN message processing.


High error rates on the CAN bus can severely impact the equipment’s electronic systems. Prompt diagnosis and resolution of CAN bus issues are essential to maintain system functionality. Regular inspection and maintenance of the CAN bus network are crucial to prevent such problems.
