Description:

This error code indicates that the Corner Post Display Unit (PDU) is not receiving the required messages from the Automatic Temperature Control Unit (ATC). This can result from communication failures, wiring issues, or faults in the ATC or PDU.

Reaction:

There is no immediate reaction from the control unit; however, the absence of these messages may lead to incomplete or missing information regarding temperature control on the PDU, affecting the operator’s ability to manage the vehicle’s climate.

Recommendations:

• Inspect Communication Lines:
  • Check the wiring and connectors between the PDU and ATC for any signs of damage, loose connections, or interference.
• Verify ATC Operation:
  • Ensure that the ATC is functioning properly and sending the required messages.
• Update Software:
  • Update the software of both the PDU and ATC 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 ATC.
• Consult Technical Support:
  • If the communication issue persists, contact technical support for further diagnostics and solutions.

Note:

Regular software updates and maintenance of communication lines are essential for preventing such issues and ensuring effective temperature control.
