  • There are cheap scanners and cheap scanners... What car? Do you want to do this remotely, because if you are in the car with the computer it seems futile... – Solar Mike Jul 5 at 11:47
  • I personally have chevrolet cruze 2012, i want to make sort of a deivce that will connect to the obd wirelessly and tell me the status, isbit possible to make this device compatible for all sorts of cars? Or each car has it own system codes? – Dudu Gvili Jul 5 at 13:26

There are companies that provide "security" systems for high end cars, and these allow remote access for a range of things, however after a friend of mine demonstrated this attack, I wouldn't use one myself:
