John Deere 3510.06 – Armrest Interface Control Unit (AIC): AIC 5 V Sensor Supply 2 Current High

This code signals an abnormally high current draw in the 5-volt sensor supply 2 circuit of the Armrest Interface Control Unit. An elevated current typically indicates a direct short to ground within the circuit, either in the wiring harness or inside one of the sensors powered by this specific 5V supply.

1. 1

   Visually inspect the wiring harness for the 5V sensor supply 2 circuit for areas where it may be rubbing against the seat frame or armrest housing, causing a short to ground.

2. 2

   Inspect all connectors on this circuit for fraying, loose pins, or corrosion.

3. 3

   Perform a sensor isolation drop test by disconnecting armrest sensors (e.g., SCV levers, hitch controls, throttle module) one at a time. If the high current code goes inactive or changes to a voltage out of range code, the unplugged sensor is internally shorted.

4. 4

   Measure the voltage and current output directly at the AIC pins for Sensor Supply 2 using a multimeter to verify if the short is in the harness or internal to the AIC board.

1. 1

   Disconnect Power

   Turn off the machine and disconnect the battery ground before servicing the CommandARM™ to prevent static damage to the circuit boards.

2. 2

   Repair Wiring

   If a short to ground was found in the harness during the visual inspection, repair the damaged wire using an approved John Deere wiring splice kit, or replace the affected harness section.

3. 3

   Replace Faulty Sensor

   If the isolation test revealed an internally shorted sensor (e.g., a faulty SCV control lever module or throttle module), remove the armrest covers and replace the specific module.

4. 4

   Replace the AIC (If Necessary)

   If the wiring is completely intact and all sensors test good, the Armrest Interface Control Unit itself has an internal short. Remove the CommandARM™ assembly covers, use a grounding strap to prevent static electricity damage, disconnect the navigation bar connector, remove the mounting screws to extract the AIC board, and install the new AIC board.

5. 5

   Recalibrate

   Reconnect the battery. Use John Deere Service ADVISOR (or the CommandCenter™ display) to clear the stored codes and perform the Armrest Interface Control Unit (AIC) Configuration and Calibration. Test all armrest functions to ensure the voltage is stable.
