Description:

This diagnostic trouble code is generated if the control software detects that after several attempts, the range cannot be engaged. This indicates a mechanical problem with the transmission. The range is disabled until the next tractor start-up.

Reaction:

When this error is detected, the transmission may experience limited or no function, as the range will be disabled.

Recommendations:

• Inspect Transmission Mechanism:
  • Check the mechanical components of the transmission for signs of wear, damage, or misalignment. Repair or replace any faulty components.
• Verify Solenoid Operation:
  • Ensure the Range B solenoid is functioning correctly. Test the solenoid and replace it if necessary.
• Check Hydraulic System:
  • Inspect the hydraulic system that controls the range engagement for any issues. Ensure there are no leaks and that the hydraulic pressure is within the specified range.
• Reset Control Software:
  • Restart the tractor to reset the control software and attempt to engage the range again.
• Consult Technical Support:
  • If the error persists, consult John Deere technical support or a certified technician for further diagnosis and resolution.

Note:

Regular maintenance of the transmission and its components is crucial for preventing mechanical failures. Addressing any mechanical issues promptly can prevent range engagement problems.
