    Going into READY mode, is generally a bad 12v battery, nothing to do with the hybrid battery. Actually a bad 12v battery will sometimes cause people to mistakenly replace the HV pack because all sorts of weird codes are thrown.

    Step 1, replace 12v battery and report back.

    12V battery or hybrid battery. They are different.

    And a "new" battery doesn't always mean a good battery. When the car is not in READY mode, the HV pack is completely disconnected. If the pack was completely dead or functioning perfectly it doesn't matter since it is physically disconnected from the vehicle through relay disconnects. So if the car is not going into READY, your problem lies with the low power 12v auxiliary bus and has nothing to do with hybrid anything.

    Who did the remanufacturing of the hv battery? That most likely is your problem.

    You can reset the car and it'll start and get into Ready mode again, but that won't fix your problem.

    Your cryptic responses without actually answering anything are useless and you won't get much useful help that way.

    "State of charge" OF WHAT is "good"? 12v battery? HV battery? How can you check the SOC of the HV battery if not in READY mode? How do you determine "good"? What can look "good" to one is poor to an actual engineer.

    Have you checked the big HV battery interlock switch? If that is not seated properly (and it often looks good but isnt) then it wont go READY. The fact that the car worked for a while after HV replacement, then died suggests the problem lies elsewhere.

    Most of the time, it is the 12v battery. Get a voltmeter on it.
    Have you checked

    What DTCs does Torque provide? You should have codes if the triangle of death is displayed. Are you able to get into ACC mode?
