Troubleshooting John Deere 748G 3 Skidder Fault Codes F475 and F477

Question:

I am currently experiencing issues with my J.D 748G 3 skidder, specifically with fault codes F475 and F477. While I have found information on F475 relating to the engine, I am unable to determine the meaning of F477. Can anyone provide assistance with this? Thank you.

If you encounter a 477 security code error, it may be due to an incompatible ECU installed on the engine or a replacement monitor not recognized by the ECU. In such cases, seeking assistance from John Deere or utilizing John Deere programming services is recommended. In my experience, resolving this issue involved replacing both the ECU and dash monitor, and programming them to communicate effectively. It's crucial to ensure that all components are properly recognized by each other to avoid further issues.
