AIC 523349.02 – AutoTrac™ Resume Switch Conflict. John Deere System Alert.

AIC 523349.02 (AIC )

Code: 523349.02



This error code highlights a malfunction within the AutoTrac™ resume switch, specifically noting that the ON and OFF contacts are registering the same value. This unusual behavior typically indicates a fault in the switch itself or an underlying issue within the circuitry, which could include a stuck switch, a short circuit, or a failure in the electrical connections.


In response to this conflict, the control unit has restricted or completely disabled the functionality of the AutoTrac™ resume switch to prevent incorrect operations and potential system errors.


  • Inspect the AutoTrac™ Resume Switch: Examine the switch for any signs of physical damage, wear, or debris that might cause it to stick or malfunction. Ensure that the switch can freely toggle between ON and OFF positions.
  • Test Electrical Circuitry: Utilize diagnostic tools to evaluate the electrical connections and circuitry of the switch. Look for shorts, opens, or inconsistent signal outputs that could be causing both contacts to show the same value.
  • Repair or Replace Faulty Components: If the switch or associated circuitry is found to be defective, make the necessary repairs or replace the faulty parts to ensure proper function.
  • Functionality Testing of the Switch: After repairs or replacement, thoroughly test the switch to ensure it operates correctly and integrates seamlessly with the AutoTrac™ system’s other controls.
  • System Reset and Operational Verification: Reset the system to clear any fault statuses set by the control software. Perform a comprehensive test to confirm that the AutoTrac™ resume switch is functioning correctly and that no further issues are detected.


Regular maintenance and prompt attention to issues with the control switches and their circuits are vital for maintaining the operational efficiency and safety of agricultural machinery. Ensuring that all components function correctly helps prevent operational disruptions and extends the lifespan of the equipment.
