Where is the fuse box that holds fuse f51 in a 2019 Model X?

    Anyone have any documentation? It’s not in the fuse box in the frunk or in the one by the gas pedal, so I’m guessing there’s a third fuse box somewhere, but I can’t find any info on it.

    Thanks in advance!

    Hi Rzod,

    I have some pretty good fuse diagrams for model X.
    For me March 2018 MCU2.
    I do not know of any electric system changes since my car was built.
    I do not see a Fuse F51 anywhere.

    What function does the fuse you are looking for support???

    F51 is the MCU power fuse in the early Model S fuse boxes. Is that what you are looking for?

    If so, no guarantee it's the same designation on other models or revisions.

    Hi guys - I’m looking for the Model X fuse for the MCU. I’ve seen two fuse boxes in my X, but corresponding diagrams I have seen don’t list the MCU fuse in either of these two fuse boxes. I was wondering if there was another fuse box somewhere that houses the fuse for the MCU. I’ve seen other reports about this fuse being labeled f51, but those were in S groups. Thanks.

    Hi Rzod,

    I answered this question on your other post.

    There is no fuse explicitly listed as an "MCU" fuse.
    The fuse you want is F236 which is located in the fuse box by your right ankle underneath the carpeting.
    This fuse on the diagrams is listed as "SCCM, iBooster IGN, ACC Sense, Rear-View Mirror, Radio, TPMS

    Any damage done to your car from removing this fuse is YOUR responsibility...
