    ECM Not Reading

    2018 Dodge Charger R/T, bypass cable installed.
    I had sent my ecm to livernois for unlock and for use with HP Tuners. Once recieved, plugged in pcm, hooked up battery, hooked up hp, turned on to read and the software is asking for a vin number. Enter my vin and does the read. After going through the whole process, only comes up with my TCM. Nothing else. Is the pcm still locked or is it something else?

    I have disconnected the battery, checked fuses, rehooked up ecm, restarted computer.

    the correct process is that you read the factory tune send for unlock and write that factory tune
