AIC 523923.04 – Low Voltage Fault at E-SCV I Control Lever. John Deere System Alert.

AIC 523923.04 (AIC )

Code: 523923.04



This error code AIC 523923.04 identifies a low voltage issue or a potential short to ground within the circuitry of the control lever for E-SCV I (Electronic Selective Control Valve I). Low voltage can hinder the lever’s ability to correctly transmit command signals, possibly due to wiring problems, degraded components, or a faulty electrical connection.


Due to this voltage deficiency, the control software has restricted or completely disabled the functionality of the E-SCV I control lever. This action prevents the lever from issuing potentially erroneous commands that could impact the operation and safety of the machinery.


  • Inspect the Wiring and Connections: Examine the electrical connections and wiring related to the E-SCV I control lever for signs of wear, corrosion, or damage that could cause a voltage drop or short to ground.
  • Diagnose the Electrical Circuit: Utilize diagnostic equipment to test the electrical circuit associated with the control lever. Check for continuity issues or resistance problems that could be contributing to the low voltage.
  • Repair or Replace Faulty Electrical Components: Address any identified issues by repairing or replacing damaged wiring or faulty components to ensure the circuit delivers the correct voltage levels.
  • Test Lever Functionality: Once the repairs are made, thoroughly test the E-SCV I control lever to ensure that it operates effectively and responds accurately to inputs.
  • System Reset and Comprehensive Testing: Reset the control system to clear any fault indications. Perform extensive testing to confirm that the control lever is fully operational and that all related systems function correctly without any voltage issues.


Regular maintenance of electrical systems and proactive troubleshooting of voltage irregularities are essential for the smooth and safe operation of agricultural machinery. Ensuring that control levers and their associated circuits operate within their designated voltage ranges helps prevent operational disruptions and extends the lifespan of the equipment. Addressing electrical issues promptly can significantly reduce downtime and enhance overall equipment reliability.
