Deere 650k VCU code

dhutch · 2025-01-05 08:55

I've got a 650k dozer that's showing a vcu 2251.9 code. Can anyone provide some suggestions on where to start or what this code pertains too? TIA

    2251.09 is the monitor lost communication with the Modular Telematics Gateway (JDLink controller).

    Thanks for posting. What's a suggested fix? Check and clean the connectors?

    Do you have an active JDLink subscription?

    No sir.

    To get rid of the code, For IT4 machines (E serial number before the last 6 digits), Remove all the JDLink (MTG) fuses. In the monitor, go to MAIN MENU – SOFTWARE - DELIVERY – DELIVERY SETTINGS – and disable. For FT4 machines (F serial number), Remove all the JDLink (MTG) fuses. In the monitor, go to MAIN MENU – OPERATION – SOFTWARE DELIVERY – DELIVERY SETTINGS – SOFTWARE DELIVERY – and disable.

    On my 650k. The code will come on and off. Will the same fix work?

    That fix worked for me, easy to do.
