When this error is detected, the transmission may experience limited or no function.


  • Inspect Solenoid Wiring:
    • Check the wiring and connections to the Range C solenoid for signs of short circuits. Look for damaged insulation or exposed wires. Repair or replace any compromised wiring.
  • Test Solenoid:
    • Test the Range C solenoid to ensure it is not damaged or causing excessive current draw. Replace any faulty solenoid components.
  • Verify Power Supply:
    • Ensure the power supply to the solenoid is stable and within the specified range. Inspect for any issues that could cause an overcurrent condition.
  • Check Control Unit:
    • Inspect the control unit for any faults or malfunctions that could affect the solenoid current. Update the control unit software if necessary.
  • Consult Technical Support:
    • If the error persists, consult John Deere technical support or a certified technician for further diagnosis and resolution.


Excessive current can damage the solenoid and associated circuitry. Regular inspection and maintenance of the solenoid and its wiring are essential to prevent short circuit issues.
