AIC 524216.09 – CAN Bus Communication Fault with PTF Control Software. John Deere System Advisory.

AIC 524216.09 (AIC )

Code: 524216.09



This error code, AIC 524216.09, indicates a data transfer problem between the Armrest Interface Control (AIC) software and the Power Take-Off Front (PTF) control software, signifying a communication issue within the Controller Area Network (CAN) bus system. The problem may stem from faults in the CAN bus itself or issues within the transmitting control software, potentially causing incorrect or lost messages that disrupt normal operations.


The control unit has responded to this communication fault by limiting or entirely disabling the functionality of the control software associated with the PTF system. This precautionary measure is intended to prevent incorrect operation or potential damage due to unreliable data communication.


  • Diagnose CAN Bus Connectivity: Use diagnostic tools to check the integrity of the CAN bus connections. Look for signs of physical damage, loose connections, or corrosion at connection points which might impair signal integrity.
  • Check Software Configuration: Ensure that the software configurations in both the AIC and PTF control systems are correct and compatible. Update or reconfigure software settings if discrepancies are found.
  • Test Data Transfer and Signal Integrity: Perform tests to ensure that messages are being transmitted and received correctly across the CAN bus. Utilize software tools to monitor live data and check for errors or lost messages.
  • Address Any Identified Faults: Repair or replace hardware components related to the CAN bus as necessary. If software issues are detected, consult with technical support for updates or bug fixes that may resolve the communication errors.
  • System Reset and Comprehensive Testing: After making necessary adjustments and repairs, reset the systems involved to ensure all settings take effect. Perform comprehensive testing to verify that communication between the AIC and PTF control software is restored and functions reliably under all operational conditions.


Maintaining robust communication across the CAN bus is critical for the synchronized operation of advanced machinery control systems. Regular system checks and timely resolution of communication issues are essential to avoid operational disruptions and ensure that the machinery operates safely and efficiently. Ensuring that all system components, both hardware, and software, are in good working order and properly configured, is key to preventing future problems.
