Recommendations:

• Inspect CAN Wiring:
  • Check the CAN bus wiring for any signs of damage, disconnections, or corrosion.
  • Ensure all connections to the ECU are secure and intact.
• Test CAN Bus Communication:
  • Use diagnostic tools to test the CAN bus communication and ensure messages are being transmitted correctly.
• Verify ECU Functionality:
  • Ensure the ECU is powered on and functioning properly.
  • Reboot the ECU or perform a software update if necessary.
• Replace Damaged Components:
  • Replace any damaged or faulty wiring or connectors that could be causing the communication issue.

Note:

Maintaining proper CAN bus communication is crucial for the accurate operation of the control systems and preventing further issues.
