AIC 524017.31 – Reverse Drive Lever Supply Voltage Fault. John Deere System Alert.

AIC 524017.31 (AIC )

Code: 524017.31



This error code, AIC 524017.31, signifies a fault in the supply voltage or switch operation of the reverse drive lever system. The incorrect status detection of the neutral and/or reverse switches suggests potential issues either directly at the switches or within the general 12-volt voltage supply circuitry. These problems could affect the switches’ ability to accurately communicate the lever’s position, leading to operational errors.


As a result of this fault, the control software has restricted the tractor’s ability to move, ensuring safety until the error is addressed. The tractor’s movement can only be restored once the reverse drive lever is moved to the corner park lock position following correction of the fault.


  • Inspect the Reverse Drive Lever Switches: Examine the neutral and reverse switches for any signs of physical damage, corrosion, or loose connections that could impair their function.
  • Check the 12-Volt Supply Voltage: Measure the voltage levels in the circuit supplying the reverse drive lever to ensure it is within the correct range and stable. Look for any voltage drops or fluctuations that could indicate wiring issues or a faulty power supply.
  • Test Switch Functionality and Electrical Continuity: Utilize diagnostic tools to test the functionality of the switches and the continuity of the electrical circuit. This includes checking for shorts, opens, or resistance issues in the wiring.
  • Repair or Replace Faulty Components: If any issues are identified with the switches or the voltage supply, repair or replace the necessary components to restore correct function and voltage levels.
  • Calibrate and Test the Reverse Drive Lever: After repairs, calibrate the system and thoroughly test the reverse drive lever to ensure that it accurately reflects the lever’s position and functions properly in all modes.
  • System Reset and Operational Verification: Reset the control system to clear any fault codes and restore default settings. Perform comprehensive testing to verify that the tractor moves appropriately and that all safety measures related to the reverse drive lever are fully functional.


Maintaining the integrity of control levers and their associated electrical systems is crucial for the safe operation of heavy machinery. Regular inspections and timely resolution of electrical or mechanical issues are essential to prevent operational disruptions and ensure equipment reliability and safety. Addressing faults in critical systems such as the reverse drive lever promptly can help avoid more severe problems and extend the lifespan of the machinery.
