AIC 524103.02 – SCV IV Control Lever Switch/Sensor Conflict. John Deere System Notification.

AIC 524103.02 (AIC )

Code: 524103.02

Shortcode:

Description:

The error code AIC 524103.02 is triggered due to a conflict within the SCV IV (Selective Control Valve IV) system, where the detent switch on the control lever is not aligned with the sensor voltage readings from the E-SCV IV sensor. This mismatch indicates that the physical position of the control lever does not correspond with the electrical signals being detected by the sensor, suggesting issues with either the sensor, switch, or the associated wiring, potentially affecting the accurate control of hydraulic functions.

Reaction:

The control unit has disabled SCV IV as a precautionary measure to prevent any potential operational errors or damage that could result from the sensor-switch conflict.

Recommendations:

  • Inspect the SCV IV Control Lever and Detent Switch: Carefully examine the control lever and its detent switch for signs of physical wear, misalignment, or mechanical damage that could influence its function. Ensure that the lever operates smoothly across its entire range of motion.
  • Test the E-SCV IV Sensor and Wiring: Utilize diagnostic tools to evaluate the voltage outputs and continuity of the sensor and wiring involved. Identify any discrepancies in the voltage levels that do not match the lever positions.
  • Resolve Electrical or Mechanical Issues: If any components are found to be faulty, such as damaged wires, poor connections, or a malfunctioning sensor, proceed with the necessary repairs or replacements to ensure accurate signal transmission.
  • Calibrate the SCV IV System: After repairs, recalibrate the sensor to ensure that it accurately reflects the lever’s positions. Calibration is crucial to synchronize the mechanical actions of the lever with the sensor’s electrical signals.
  • System Reset and Functional Testing: Reset the system to clear any stored faults. Conduct a series of functional tests to verify that SCV IV is fully operational and responding correctly to control inputs without any further conflicts.

Note:

Regular maintenance and calibration of SCV systems and their components are essential to maintain the reliable operation of hydraulic machinery. Frequent inspections and timely intervention when discrepancies are detected help ensure the machinery operates efficiently and safely. Proper synchronization between mechanical movements and sensor readings is crucial for the precise operation of control systems.
