    Recovering 1VD 200 Series 2018 Sahara

    Write time out occurred at approximately 20%.
    Unable to recover.
    I have tried to bench the ECU using multiple tools without success.
    The MAPS are intact, I wrote factory firmware back to the ECU and the vehicle will not start, Techstream will not communicate and it cannot be ID'd.
    Checksum is ok.

    What is the process to recover this ECU once HPTuners has bricked it?

    I will add that this is the second time a write timeout occurred, however I was able to recover via OBD using another tool as the write progress must have finished the ECU side and moved onto the transmission (perhaps).

    Thanks.

    Tried 3 other tools, no good. All are able to communicate with the ECM on the bench and read/write. The maps are written to the ECM and checksum is ok.
