Porsche immobilizer
Hello, I have a Porsche Macan 2015 diesel pcm 3.0 that was in an accident with a major left side impact. Only the left head airbag and the driver's seat airbag were deployed, the vehicle could no longer start, no crank because the pyrofuse was triggered so I bypassed the pyrofuse on the positive terminal then the vehicle was able to start but the engine runs for 5 seconds then it cuts out. I did a diagnostic with a Launch tablet which tells me the code p157000 "ECU blocked" and the code 170100 "transmission control unit blocked". Does the Porsche ECU block after an accident and cause an immobilizer? And can you unlock this only with the ECU in hand removed from the vehicle? Or we can unlock with Piwis without a ppn online
I would like to point out that the vehicle is equipped with an alarm and VTS system with PCC and that the central locking no longer works because the driver's door is damaged and the rear door, so the vehicle does not respond when I press the control buttons to open and close the vehicle.

Ok so if I understand correctly with the piwis program without connecting online with a ppn. I can unlock my ecu which was blocked after the side impact accident in the door driver. And restart the car. Because it start 3secondes and it cut
