Check the cause
Cycle the key switch (power down completely, wait a few moments, and restart the engine) to see if the module recovers from a temporary glitch and the code clears.
Verify the battery is fully charged and the alternator is outputting the correct voltage, as low voltage can cause the module to lose power during its boot sequence.
Check the unswitched and switched power supply fuses and harness connections leading to the XSC module to ensure it is receiving consistent power.
Repair steps
Connect diagnostic tool
Connect the John Deere Service ADVISOR™ diagnostic tool to the machine.
Reprogram module
Attempt to reprogram the Steering System Control Unit (XSC) using the most current software payload file.
Perform calibrations
If the software update is successful, perform all necessary steering system configurations and calibrations (e.g., wheel angle sensor calibration) as prompted by Service ADVISOR.
Verify repair
Clear the diagnostic trouble codes and cycle the key switch to verify the repair.
Replace module
If the XSC control unit cannot be reprogrammed, fails the software update, or the 000611.09 code immediately returns, the internal hardware/software of the module is permanently corrupted. You must replace the Steering System Control Unit (XSC).
