AIC 522769.09 – Missing LIN Message from Armrest Hitch Controls Module. John Deere System Alert.

AIC 522769.09 (AIC )

Code: 522769.09

Shortcode:

Description:

This error code indicates a communication failure within the hitch controls of the armrest, specifically pointing to a missing LIN message that the Armrest Interface Control software (AIC) is expected to receive from the armrest hitch controls module. The issue is localized to data transfer problems between the AIC and the LIN Bus module at position M, suggesting a malfunction either in the LIN Bus system itself or in the module responsible for transmitting data.

Reaction:

Due to this communication breakdown, the control unit has restricted the functionality of the hitch controls to a limited mode, aiming to prevent potential operational errors and to maintain the system’s overall safety and reliability.

Recommendations:

  • Inspect LIN Bus Module at Position M: Thoroughly check the LIN Bus module for any signs of damage or malfunction that could disrupt data transmission.
  • Diagnose Connectivity and Network Integrity: Employ diagnostic tools to evaluate the connectivity and integrity of the LIN Bus network, particularly focusing on the modules and connections at position M.
  • Rectify Wiring and Connectivity Issues: Address any detected issues with wiring or connections that may impair communication. Ensure all connections are secure and free of corrosion or damage.
  • Replace Faulty LIN Bus Module if Necessary: If the LIN Bus module at position M is found to be defective, replacing it may be required to restore proper communication within the system.
  • Reset the System and Conduct Comprehensive Tests: After resolving the identified issues, reset the system to clear any error states and conduct comprehensive tests to ensure that communication has been fully restored and that the hitch controls are operating correctly.

Note:

Regular maintenance and proactive monitoring of the LIN Bus and its associated modules are essential to prevent communication failures that can lead to operational disruptions. Ensuring that all system components function seamlessly and effectively helps maintain the efficiency and safety of the machinery.
