OBD2 Scanner MS309 Universal Car Engine Fault Code Reader, Check Engine Light and Emission Monitor Status, OBDII CAN Diagnostic Scan Tool

The Autel MS309 is one of those tools every car owner should have. It was super easy to use, quickly read my check engine code, and saved me a trip to the mechanic. Compact, reliable, and perfect for basic diagnostics at home.

Good quality scanner. Simplistic and does the job.

This device is a must have! Self sufficiency is power. I have an exotic foreign vehicle and the OBD2 scanner works perfectly. I don’t have time to go to the dealer or wait on anyone. I detected the issue, cleared the check engine light - since I know it’s safe to drive temporarily until I get to the dealership. This tool is great for everyone - especially women and first time car owners. It will save you money and time because you know exactly what the issue is that needs repairing. No one will be able to pull wool over your eyes again. Durable and easy to connect. Great purchase!

Was going to write (with one star): MaxiScan MS309 is not on the manufacturer website. It is not listed in the current products nor in the legacy tab, which means no user manual. But, I was using the included QR code on my phone, and that site must be outdated? Went to their webpage on laptop and MS309 is supported with downloadable user guide. I have a new gas cap and had Trac Off and Check Engine lights on Tacoma. MS309 gave me 2 codes related to that (P0441 and P0455) with description. MS309 worked great and easy and on first try.

Easy to use. Worked great in my 2018 gmc. Picked up the issue even when the dealership missed it or maybe they just over looked it. Now I can tell them what to fix.

Needed a cheap OBD scanner that I could keep in the car while I monitored when the car finished all the EVAP system checks so I could go get my state inspection. Autel is a known good aftermarket brand. Easy to use and read. This is not a bi-directional scan tool so its not supposed to be able to do a ton of diagnostics. Code reader, freeze frame data, and system monitor checks. What more could you ask for at this price.

I was reading a customer review and when I tell you that man SOLD ME!! He did just that. He went into detail about the product and how he used it! When I tell you it did not fail me! I have a 2011 Ford Fusion Hybrid and it was gonna cost $250 just for them to hook it up to the computer. Lo and behold I come to Amazon and they had just what I needed to find out what exactly was wrong with my car. Code accuracy, instructions clear, value for the money is GREAT. It works well, fit right in.

The price is great and the features described would be too if they worked on the Prius Gen2 and Gen3. The unit is well constructed and has a solidly attached OBD cable with a nice plug. The controls are easy to understand and to use. The feature set is somewhat limited but the price is very low and seems to be a good value. However when I used it on my 2008 and 2012 prii, The only category available that was labeled was 'engine'. There were two other categories identified only by hexadecimal numbers. I could see some information related to emissions and perhaps the engine, but no error codes were apparent. This is despite the fact that my car wouldn't drive and that half the dash lights were lit up including the Master Warning triangle light, the VSC and the ABS lights. This should indicate an issue in the brake system, but there were no codes to be read. I understand that for Prius, its better to have a 'techstream' reader that is more suitable for the nuances of this vehicle. The bottom line is that I would consider buying this nicely designed device for a gas powered car, but if you have hybrid or electric, then this device may not suit your needs. Its going back.

Compré este pequeñín para revisar códigos de mis carros en casa. Es muy rápido, y aunque es muy básico, bien vale la pena; pues lo podemos transportar en la guantera, o con la herramienta. También resulta una gran ayuda si te gusta hacer mecánica en casa, o para dar seguimiento a fallas intermitentes o recurrentes. Todo muy bien. Sin embargo, no pude encontrar la marca Autel por ningún lado ni en el producto, ni el empaque.

yes,yes,simple,fast...100% good
