AIC 523805.02 – Signal Out of Range in Multi-Function Lever Fore-Aft Axis. John Deere System Notification.

AIC 523805.02 (AIC )

Code: 523805.02

Shortcode:

Description:

This error code AIC 523805.02 reports a mismatch between the voltage received and the actual position of the multi-function lever’s fore-aft axis. This discrepancy suggests an issue with the lever’s sensor system or associated electronics, potentially due to incorrect calibration, a faulty sensor, or wiring problems that are causing the voltage signals to misalign with the physical position of the lever.

Reaction:

Due to this detected signal anomaly, the control software has limited or completely disabled the functionality of the multi-function lever in the fore-aft direction to prevent erroneous machine operations that could stem from inaccurate lever position data.

Recommendations:

  • Inspect the Multi-Function Lever and Associated Sensors: Examine the multi-function lever, focusing on the fore-aft axis components for any signs of physical damage, misalignment, or wear that could affect signal accuracy.
  • Check Electrical Connections and Circuitry: Assess the wiring and connections for the sensors associated with the fore-aft axis of the lever. Look for loose, corroded, or damaged wires that could impact signal transmission.
  • Calibrate or Replace Faulty Sensors: If the sensors are found to be improperly calibrated or defective, recalibrate them according to manufacturer specifications, or replace them if necessary to ensure accurate positional feedback.
  • Test Lever Functionality: After addressing the potential issues, test the lever to ensure that the voltage readings now correctly reflect its physical position in the fore-aft axis.
  • System Reset and Comprehensive Testing: Reset the control system to remove any limitations set due to the fault. Perform extensive operational tests to confirm that the multi-function lever and its fore-aft control are functioning correctly and reliably.

Note:

Regular maintenance of control levers and their sensors is essential for ensuring the accurate operation of machinery. This includes periodic checks and calibration of sensors to align with mechanical movements. Addressing discrepancies in signal and position promptly helps maintain operational efficiency and prevents potential safety issues in machinery operations.
