AIC 521409.02 – Armrest Multi-Function Lever Module Circuit Fault. John Deere AIC System Alert.

AIC 521409.02 (AIC )

Code: 521409.02

Shortcode:

Description:

This error code identifies a circuit fault in the Armrest Multi-Function Lever Module, specifically with button 1 on the multi-function lever. The fault is related to an error in reading the signal from the front left switch of the lever. This indicates a disruption or malfunction within the circuitry that may affect the signal integrity and operational reliability of the lever.

Reaction:

Due to this detected fault, the control unit has disabled the function associated with this part of the multi-function lever to prevent incorrect operations or further complications.

Recommendations:

  • Inspect and Test the Affected Switch and Circuit: Check the front left switch for physical damage or wear that might affect its operation. Test the circuit for continuity and proper signal transmission.
  • Diagnose Electrical Connections and Wiring: Examine all electrical connections and wiring related to the malfunctioning switch to identify any loose, damaged, or corroded components that could impair functionality.
  • Replace Faulty Components: If any components of the circuit or the switch itself are found to be faulty, replace them to ensure the integrity and functionality of the multi-function lever.
  • System Reset and Functionality Testing: After repairs or replacements, reset the system to clear any error states and conduct thorough functionality tests to verify that all components of the multi-function lever are operating correctly without any signal disruptions.

Note:

Regular checks and maintenance of electrical components and circuits in agricultural machinery controls are critical to avoid operational disruptions and ensure safety. Prompt attention to symptoms of faults and conducting routine system diagnostics can greatly reduce the risk of more extensive system failures. Proactive maintenance ensures long-term reliability and performance of the machinery.
