AIC 522553.02 – Field Cruise/Engine Set Speed Button Circuit Conflict. John Deere System Notification.

AIC 522553.02 (AIC )

Code: 522553.02



The error code AIC 522553.02 highlights a fault within the engine speed control module, specifically involving the Field Cruise/Engine Set Speed on/off button. The issue is identified by both the ON and OFF contacts of the button registering the same value, suggesting that the switch may be stuck, or there could be an underlying defect in the circuit.


In response to this circuit conflict, the control unit has disabled the functionality of the Field Cruise/Engine Set Speed button to prevent unintended engine behavior and to safeguard the operational integrity of the machinery.


  • Inspect the Field Cruise/Engine Set Speed Button: Examine the button for any signs of sticking, mechanical blockage, or physical damage that might prevent it from toggling between states.
  • Check Electrical Connections and Circuitry: Investigate the electrical connections and circuit components related to the button. Look for issues such as shorts, disconnections, or deteriorated components that could cause both contacts to show the same value.
  • Repair or Replace Defective Parts: If any defects are identified in the switch mechanism or its circuitry, undertake necessary repairs or replace the defective parts to ensure proper functionality.
  • Test Button Operation: After repairs or replacement, thoroughly test the button to ensure it correctly alternates between ON and OFF states without any issues.
  • System Reset and Comprehensive Testing: Reset the control system to clear any fault statuses set due to the conflict. Perform a detailed operational test to confirm that the Field Cruise/Engine Set Speed button is functioning correctly and that the engine responds appropriately to its settings.


Maintaining the functionality and reliability of control buttons and their circuits is critical for the efficient operation of agricultural machinery. Routine checks and timely intervention when faults are detected can prevent operational disruptions and extend the lifespan of the equipment.
