That's true for most newer cars. Some really old OBD-II cars will not retest fast enough and pass.
Basically when OBD-II rolled out in 1996, code scanners were so few and far between that the ECMs would retest much longer cycles. You could clear codes and eek through, so CARB and EPA required shorter retesting periods.
The "clear" function clears some non-historical codes, but when the ECM re-runs the tests, they'll come right back if they're still failing. So it won't work for a smog check with any car made in the last 15-20 years.
It's still a concern for a test drive, so you should definitely test drive a car for 15 minutes of run time, and then retest with a scan tool after.
Bluetooth range is only 90ft and most devices identify the device that's trying to pair. There's also pins required on both ends for devices of a certain class and indicator icons when you're tethering via Bluetooth.
Not to mention, the nefarious person would need to know the MAC address of the device you originally paired to and most of those dongles don't have more than a 15ft range... so they'd be pretty close by when grabbing this.
just remember you can use these code scanner tools to turn off the check engine light, but dont even think about taking said car in to be inspected as even though the check engine light is off on the dashboard, the onboard computer still knows there is a problem and said car will not pass.

And that's how it's supposed to be IMO to deter some of the shady practices. Usually one would have to drive the car for some period of time afterwards for codes to clear and if the problem persists then codes will pop again which is also good because you don't want to drive the car that might be unsafe or having important issues. Some feedback on scanners people complain about codes coming back and make scanner at fault for their broken car and I can't even comprehend why they think that ANY scanner should fix their car🤦🏻 ♂️, it's like measuring something with multimeter and expecting that to fix the problem by itself.

Great little scanner to quick read readiness monitors & some light codes. These scanners are limited in pulling codes of course given the cost......I bought 2 when I saw this listing and they were delivered 3 hours later!

Can it read transmission fluid temperature?

The actual issue is that the computer records when a code was last cleared. So regardless of issue or not or speed, emission won't pass the vehicle if a code has recently been cleared.

Works great for pulling codes and resetting lights.
