Description:

This diagnostic trouble code is generated if the control software detects that the current value at the Range A solenoid is too low. This may indicate an open circuit.

Reaction:

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

Recommendations:

• Inspect Solenoid Wiring:
  • Check the wiring and connections to the Range A solenoid for signs of damage or open circuits. Repair or replace any compromised wiring.
• Test Solenoid:
  • Test the Range A solenoid to ensure it is functioning correctly and drawing the proper current. 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 a drop in current.
• 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.

Note:

Maintaining the solenoid and its wiring is crucial for the proper function of the transmission. Regular inspections and timely repairs can prevent open circuit issues.
