Description:

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

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:

• Inspect CAN Bus Connections:
  • Check all CAN bus connections between the ATC/ETC 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 ATC/ETC and RLC control software are updated to the latest versions to address any potential issues with CAN message processing.

Note:

Consistent communication between the ATC/ETC 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.
