Why some OBD tools don't pick up any error codes?
Each time my car got issues, i run to different shops to scan my vehicle. They all use different diagnostics tools but only 1 out of 4 will actually find an issue within the vehicle. Some shops use more than one diagnostics tool. I always ask not to delete error codes, so that if they cant pick up any issues, maybe the next shop will.
Why is that ?
Car is a Hyundai Tucson 2009, not a Tesla or Bugatti...

Not all Scan Tools are the same, OBD2 are the basic tools. Enhanced EOBD, and CAN capable scanners are more advanced and can do more.

I don't know what is happening, but it IS NOT the scan tools used. Either your OBDII system is reporting a code, or it isn't.
