AIC 516317.06 – 12V Sensor Supply 2 High Current. John Deere AIC System Alert.

AIC 516317.06 (AIC )

Code: 516317.06



This code, AIC 516317.06, indicates an overcurrent condition in the 12V sensor supply 2 of the Armrest Interface Control Unit. The high current is typically due to a short to ground, which could result from damaged insulation, exposed wiring, or faulty electrical connections. Such conditions are not only detrimental to the electrical system’s integrity but also pose risks such as overheating and potential fire hazards. This problem is often observed in equipment subjected to rigorous use or environments that accelerate wear and tear on electrical components.


To mitigate any potential damage from the overcurrent, the system has automatically degraded the function of affected components.


  • Inspect the 12V sensor supply 2 circuit for any signs of shorts to ground, focusing particularly on areas where insulation may be compromised.
  • Measure the current with an ammeter to confirm that it is above safe operating levels and identify the specific sections of the circuit contributing to the high current.
  • Repair or replace any damaged wiring or connectors. Consider implementing additional protective measures, such as better-quality insulation or protective conduit, to enhance durability against environmental factors.
  • Once repairs are made, recalibrate any affected systems and conduct a full operational test to ensure that the issue has been resolved and that no other components have been impacted.


Regular preventive maintenance and immediate response to any signs of electrical system distress are crucial for maintaining the operational safety and efficiency of John Deere machinery. Properly maintained electrical systems help prevent unexpected downtime and extend the service life of the equipment.
