Description:

This diagnostic trouble code (DTC) UIC 000237.02 is generated when the Vehicle Identification Number (VIN) from other control units is not the same as expected. This indicates a mismatch in the VIN information across different control units.

Reaction:

When this error occurs, the control unit may prevent certain functions or operations to ensure vehicle security and integrity, potentially limiting vehicle performance.

Recommendations:

• Verify VIN Consistency:
  • Check the VIN stored in all control units and ensure they match the official VIN of the vehicle.
  • Use diagnostic tools to read and compare VIN information from all control units.
• Reprogram Control Units:
  • If a mismatch is found, reprogram the control units with the correct VIN information.
  • Ensure that the programming procedure is done correctly to prevent future mismatches.
• Consult Technical Support:
  • If the issue persists after reprogramming, contact John Deere technical support for further assistance and potential software updates.

Note:

Ensure all control units are using the latest software versions to avoid compatibility issues.
