Description:

This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Armrest Control Unit (ACU). This can be due to communication issues, wiring problems, or faults in the ACU or PDU.

Reaction:

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

Recommendations:

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

Note:

Regular maintenance and checks of the communication lines and control units are crucial for preventing communication-related faults and ensuring smooth operation.
