Description:

This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Chassis Control Unit (CCU). This can occur due to communication problems, faulty wiring, or malfunctions in the CCU or PDU.

Reaction:

There is no immediate reaction from the control unit; however, the lack of communication may result in incomplete or missing chassis-related information on the PDU, affecting the operator’s ability to monitor and control chassis functions.

Recommendations:

• Inspect Communication Lines:
  • Check the wiring and connectors between the PDU and CCU for any signs of damage, loose connections, or interference.
• Verify CCU Operation:
  • Ensure that the CCU is functioning correctly and transmitting messages as expected.
• Update Software:
  • Update the software of both the PDU and CCU to the latest versions to ensure compatibility and proper communication protocols.
• Reset the System:
  • Perform a system reset to reestablish communication between the PDU and CCU.
• Consult Technical Support:
  • If the communication issue persists, contact technical support for further diagnostics and solutions.

Note:

Regular maintenance of communication lines and software updates can prevent such issues and ensure reliable operation of chassis functions.
