  • I hope it supports a whole lot more than 3000 codes, the car company I work for has over 10,000 just for powertrain and communication.
  • I think that would depends on what app you use with it
  • can it reset codes? that is the big thing to me.
  • Also dependent on app.. But torque is pretty awesome. And yes you can read and then clear codes. I've used it in probably 10-15 different vehicles over the years. Never an issue. I don't have this particular obdii reader. But they're all basically the same.
  • Bought one, how did you guys know I need one of these? Lol dealing with check engine light coming on.
