AIC 516316.06 – 12V Sensor Supply 1 High Current. John Deere AIC System Alert.

AIC 516316.06 (AIC )

Code: 516316.06



This diagnostic trouble code, AIC 516316.06, is generated when the current in the 12V sensor supply 1 of the Armrest Interface Control Unit exceeds safe levels, indicating a likely short to ground within the circuit. This abnormal current can lead to significant issues within the electrical system.


In response to this high current condition, the system has degraded the functionality of the affected components to prevent further damage and maintain safety.


  • Immediately inspect the 12V sensor supply 1 circuit for potential shorts to ground. Pay close attention to the wiring and connections for any signs of damage or deterioration.
  • Use an ammeter to measure the current flow through the circuit, confirming it is above recommended levels, and to help identify the exact location of the excessive current.
  • Check for and replace any damaged components or wiring within the circuit that might be contributing to the high current situation.
  • After making necessary repairs or replacements, recalibrate the circuit if required and conduct extensive testing to ensure that the current has returned to normal levels and the system’s functionality is fully restored.


Regular monitoring and maintenance of electrical systems are essential to ensure the integrity and safety of the equipment. Addressing electrical issues promptly helps prevent operational failures and extends the lifespan of the machinery.
