Yep. If you're going to do any troubleshooting on a modern car, you need at least a DTC scanner. Cars nowadays are pretty good at diagnosing themselves and most of the time all you need to do is grab the DTC and Google it. With an OBD/CAN monitor, you can look at real-time parameters and look for things that aren't in spec.
