AIC 521574.09 – Missing LIN Message from Armrest Middle Right Module. John Deere System Alert.

AIC 521574.09 (AIC )

Code: 521574.09



The error AIC 521574.09 is reported when the Armrest Interface Control software (AIC) fails to receive a LIN message from the armrest middle right module. This communication breakdown involves data transfer issues between the AIC and the LIN Bus at positions F and G, suggesting problems either with the LIN Bus itself or the modules transmitting from these positions.


Due to this communication failure, the control unit has limited the functionality of the affected module to reduce the risk of operational errors and ensure system stability.


  • Examine LIN Bus Modules at Positions F and G: Inspect these modules for any physical damage or electronic discrepancies that could be impacting their ability to transmit data.
  • Conduct Thorough Diagnostic Tests: Use advanced diagnostic tools to check the communication effectiveness and integrity of the LIN Bus modules at positions F and G.
  • Resolve Wiring and Connectivity Issues: Ensure all wiring and connections associated with these positions are intact and functioning properly. Repair or replace any faulty elements.
  • Consider Module Replacement: If either of the LIN Bus modules at positions F or G is found to be defective, replacing it might be necessary to restore full communication capabilities.
  • System Reset and Comprehensive Testing: After addressing the issues, reset the system and perform detailed operational tests to confirm that the armrest middle right module is fully functional and that all LIN messages are being properly received.


Maintaining robust communication networks within agricultural machinery is essential for operational efficiency and safety. Regular monitoring and maintenance of the LIN Bus and its components can prevent significant disruptions and ensure continuous, reliable performance of the machinery.
