RLC 001231.12 – Implement CAN Bus, High Error Rate

RLC 001231.12 (RLC 1231.12)

Code: 001231.12

Shortcode: 1231.12

Description:

This error code indicates that the CAN bus messages received cannot all be processed, possibly due to a CAN bus overload or an internal control software error.

Reaction:

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.

Recommendations:

  • Monitor Implement CAN Bus Load:
    • Check the load on the implement CAN bus to ensure it is within acceptable limits. Reduce the number of devices on the CAN bus if it is overloaded.
  • Inspect Implement CAN Bus Connections:
    • Inspect all connections on the implement CAN bus for signs of damage, loose connections, or corrosion. Secure or replace any compromised connectors.
  • Verify Termination Resistors:
    • Ensure that proper termination resistors are installed at both ends of the implement CAN bus network. Incorrect termination can lead to communication errors.
  • Update Control Software:
    • Ensure that the control software is updated to the latest version to address any potential issues with CAN bus message handling.
  • Consult Technical Support:
    • If the issue persists, contact technical support for further diagnostics and assistance.

Note:

High error rates on the implement CAN bus can lead to significant communication issues and affect the overall functionality of the vehicle’s electronic systems. Regular inspection and maintenance of the CAN bus network are crucial to prevent such problems.
