    Trying to read 2018 Infiniti Q60S and getting a "x7F: Negative Response Code"

    I am trying to read my 2018 Infiniti Q60 with 3.0 VR30 using SH_7253_131 and the other one and both are giving me the same error codes. "Reader upload request:x7F Negative response code"

    It says the operating system is 14GE6A.

    Any ideas?

    Haven't tried reading an Infiniti, but when I get an x7f its either low system voltage or bad USB cable.

    I updated to the beta software and now I am getting a "FAILED TO RETRIEVE FLASH DATA". I sent the infolog to HPT and am awaiting their response.

    0x7F error on Nissan is almost exclusively battery load too high (if it's not bad USB cable related). Need to make sure everything is turned off, these things are finnicky. No A/C, no headlights, no radio, etc.

    As for the failed to retrieve flash data, it's because we don't have your file stored on the server. The read of your vehicle is an actual read of the calibration, and a "virtual" read of the OS section. If we don't have your file stored on our server we don't allow the read to finish. We have to purchase it and then create a definition, then you'll perform the read after all of that is done.

    Also the controller type for the VR30 is SH_7253_331, but on downloading latest beta (when it's ready, it isn't yet) it should auto-identify as that controller.

    I'll reply to your ticket when it's ready. I just wanted to post that publicly since there have been a couple tickets from confused people on this platform.

    Will this have to be done before tuning every Nissan/Infiniti ECM?

    Responded to your ticket but since it's posted here publicly: tuned with ecutek. They lock the read. Have to return to stock first.

    I was able to put the ECM back to stock and successfully read the ECM.


    I notice that engine diag and the transmission tables are blank. Will those be available at a later date?

    Both are being worked on but there is no ETA
