AIC 524102.02 – SCV V Control Lever Switch/Sensor Conflict. John Deere System Notification.

AIC 524102.02 (AIC )

Code: 524102.02



This error code, AIC 524102.02, points to a conflict within the SCV V (Selective Control Valve V) system, specifically between the detent switch on the control lever and the sensor voltage readings from the E-SCV V sensor. There is a discrepancy indicating that the physical position of the control lever does not align with the voltage being detected by the sensor. This could be due to a malfunction in the sensor, the switch, or associated wiring, which may lead to incorrect operation or signaling of the hydraulic functions controlled by SCV V.


Due to this detected conflict, the control unit has disabled SCV IV (possibly a typo in the alert, intended as SCV V) to prevent incorrect hydraulic operations, which could result in system damage or operational hazards.


  • Inspect the SCV V Control Lever and Detent Switch: Examine the control lever and its detent switch for any physical damage or signs of wear that might impact its accurate positioning and function. Ensure that the lever is correctly aligned and moves smoothly across all positions.
  • Diagnose the E-SCV V Sensor and Electrical Connections: Use diagnostic tools to assess the sensor and the wiring involved. Check for accurate voltage readings corresponding to different lever positions and identify any electrical irregularities such as shorts or disconnections.
  • Repair or Replace Faulty Components: If the sensor, switch, or wiring is found to be defective, proceed with repairs or replacements. Ensure all new installations are securely connected and properly configured.
  • Calibrate the SCV V System: After repairing or replacing any parts, recalibrate the system to ensure the control lever and sensor are in sync, providing accurate readings that reflect the actual lever positions.
  • System Reset and Operational Testing: Reset the control system to clear any errors. Perform extensive operational tests to confirm the functionality of SCV V and ensure that there are no remaining conflicts or issues in the system.


Regular maintenance of the SCV systems and their components is vital to ensure the effective and safe operation of machinery. Frequent checks and immediate rectification of any detected issues help maintain system integrity, prevent potential malfunctions, and extend the lifespan of the equipment. Ensuring that control levers and sensors are properly calibrated and functioning correctly is crucial for precise hydraulic control.
