Note: Some vehicle models have a "delayed power-off" function for the fuse interface. To ensure the VCC regular power interface is correct, it is necessary to open the door when the ignition is switched off, turn the door lock to the locked position, use the key to lock the vehicle (into a simulated locked state), and then wait for 5 to 10 minutes before identifying an interface with a voltage of around 12V (A known model:BMW 525)
