How do you use an OBD2 scanner?

Find the 16-pin port (usually under the steering column), plug in with the ignition on, and read the stored fault codes. Look the code up before clearing it — the code is the clue, not the cure.

Do car diagnostic tools work?

For reading and clearing standard engine codes on 1996+ OBDII/EOBD cars, yes. Manufacturer-locked modules like ABS or airbags can need brand-specific kit on some marques.
