Does the BLCKTEC 440 work on my car?

It works on most cars and light trucks sold in the US from 1996 on, and on 12V diesel vehicles. Chevrolet Equinox and similar models are covered for engine and emissions codes.

Can it reset the check-engine light?

Yes. It can clear codes and turn off the check-engine light once the underlying fault is fixed. Clearing codes without a repair will usually bring the light back.

Do I need a phone to use it?

No. The 2.8-inch color screen shows codes and readiness status on its own. Bluetooth is there if you want to use the companion app.

Will it pass an emissions test check?

It shows readiness monitors, so you can see whether the car is ready for a smog test. It does not certify the test itself.

Does it read ABS or airbag codes?

No. It covers the 10 standard OBD2 engine and emissions modes, not ABS, airbag or transmission modules.

How does it compare with phone-first scanners?

It stands out for its built-in color screen and attached cable, so it works without a phone. Phone-first scanners such as BlueDriver typically offer deeper manufacturer-specific data and ABS coverage.
