AIC 522189.11 – Stuck or Defective iTEC™ Program Selection Switch. John Deere System Advisory.

AIC 522189.11 (AIC )

Code: 522189.11



This error code arises when the switch for the iTEC™ program selection is pressed for an excessively long duration, which may signal that the switch is either stuck, defective, or experiencing a shorted circuit. This prolonged activation could result from mechanical sticking, debris obstruction, or an electrical fault within the switch mechanism.


The control software has responded by limiting or completely disabling the functionality of the iTEC™ program selection switch to prevent unintended actions and to safeguard the system’s operational integrity.


  • Inspect the Switch for Mechanical Flaws: Carefully examine the iTEC™ program selection switch for any signs of physical wear, damage, or obstruction by foreign materials that could cause it to stick.
  • Check Electrical Connections and Circuitry: Assess the electrical connections and circuitry associated with the switch for any signs of short circuits or other faults that might be causing abnormal behavior.
  • Clean or Replace the Switch: If the switch is dirty or mechanically flawed, clean or repair it as necessary. If issues persist or the switch is found to be defective, replace it to ensure proper functionality.
  • Test Switch Operation: After cleaning, repairing, or replacing the switch, thoroughly test it to ensure it is functioning correctly and releasing properly after activation.
  • Reset the System and Verify Functionality: Once the switch issue is resolved, reset the control system to clear any error states and perform a full functionality test to ensure no other issues remain.


Regular checks and prompt maintenance of control switches are vital for preventing operational disruptions and maintaining the efficiency of farm machinery. Ensuring that all components are in good working order and responding correctly to inputs is essential for safe and effective equipment operation.
