Is it possible to create an OBDII killer (similar to usb killer)?

Question

Electronics

Good afternoon!
I'm interested in such a thing, the so-called USB Killer has been on the market for many years - a device that burns everything that is on the way along the DATA tracks using high voltage. And now the question is, is it possible to implement this only from the side of the car to devices connected via OBDII? Are there ready-made implementations of these devices?

Answer 1

can.
the circuit is elementary, the same as in the usb-killer, only connect the high-voltage outputs to the corresponding signal lines of the OBD2 interface.
plus there is a bit more signal than in usb.
well, it’s more powerful to make a scheme for farming, the voltage and current will be more powerful for obd.
main question - why the hell??
scoundrels for a car in bulk are simpler and cheaper.

Answer 2

Kan bus auto is somewhat more resistant to damage than chips on motherboards, but in general it is also possible to burn, only more voltage is needed.
And so any electronics without special protection is vulnerable to these types of attacks.

Answer 3

with a reliably reproducible result - most likely it will not work, or the device will not be similar in size to standard adapter cases. a completely different energy impact is required compared to the PC version.
