Review on CGSULIT OBD2 Scanner Car Code Reader, SC301: Comprehensive Diagnostic Scan Tool for Check Engine Light, Emission Analysis, O2 Sensor Test, Smog Check - Car Health Monitor and Repair Tool (Black) by John Jones

It's really easy to use, it has real-time data reading and saving function, you can save 3 sessions in it. You can also search for error codes from most car manufacturers. It also allows you to reset the engine light if necessary. Press the button and all systems will be scanned automatically. It also has a USB cable so you can connect it to your computer. I got it instead of the 201 device, I thought it was a more advanced model, although I'm not sure of the difference yet. To be honest, I'm tired of the dealer. told me they ran diagnostics but never fixed the problem with my car. So I wanted to see how much bullshit they're talking about.
