If you leave the key in the car and get out, the engine stays on? If you have the key removed from the vehicle (get out, close door) while you watch the instrument cluster, does the engine shut off as soon as "key not in vehicle" comes up?

What if you put the car in neutral and apply the emergency brake. Now the car is not in park. If you have the key removed from the vehicle, does it stay running?

Advanced Key is processed by the J393, address 0x46, not the J519, address 0x09. Maybe authorization, address 0x05, which is built into the J393.

I do not have an advanced key. I have start-stop button so i can start it without putting the key in.

before, when i leave the engine on, open the door and get out, the car would turn off the engine.
