AIC 522189.02 – Circuit Fault in iTEC™ Program Selection Switch. John Deere System Notification.

AIC 522189.02 (AIC )

Code: 522189.02

Shortcode:

Description:

The error code AIC 522189.02 highlights a circuit fault involving the iTEC™ program selection switch. Specifically, an incorrect switch logic has been detected at the switch for iTEC™ program sequences 3 and 4, suggesting a potential fault in either the switch itself or its circuit. This could be due to wiring issues, a malfunctioning switch component, or software errors affecting switch operation.

Reaction:

As a result of this fault, the iTEC™ functionalities related to the affected sequences have been disabled by the control unit to prevent incorrect operations and potential damage to the system.

Recommendations:

  • Inspect the iTEC™ Switch and Associated Wiring: Check for physical damage, signs of wear, or any disconnections in the wiring connected to the iTEC™ switch. Ensure all connections are secure and intact.
  • Diagnose Circuit and Switch Logic: Use diagnostic tools to evaluate the switch logic and the electrical pathways involved in sequences 3 and 4. Look for inconsistencies or abnormalities in the switch behavior.
  • Repair or Replace Faulty Components: If a fault in the switch or circuit is confirmed, proceed with repairs or replace the defective parts to ensure proper functionality.
  • Test Switch Operation: After repairs, thoroughly test the iTEC™ switch to ensure it operates correctly across all sequences, with particular attention to sequences 3 and 4.
  • System Reset and Operational Check: Reset the system to clear any error states induced by the fault. Perform a comprehensive operational check to confirm that all iTEC™ functions are fully restored and functioning as intended.

Note:

Regular checks and timely maintenance of switch circuits in agricultural machinery are crucial for avoiding operational failures. Ensuring that all system components function correctly helps maintain the machinery’s efficiency and operational safety, significantly reducing the risk of unexpected downtime.
