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

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!

It scans codes and can clear codes. Works on foreign cars. Not difficult to use. Not much else to say.

For the price, this is a great scanner. I have a 2005 Jeep Cherokee that has a lot of quirks. I love not having a car payment, so I am hoping to keep driving this vehicle for as long as possible. Recently, my husband’s vehicle needed a jump, so we used the Jeep (which has a new battery), and immediately I got a check engine light. The Jeep had just been at the shop, so I assumed the jump had triggered an electrical code. I had a different brand code reader that I had purchased a few years back. That code reader showed two codes which were seemingly unrelated and hard to believe would occur simultaneously. That reader would not clear the codes, so after an internet search and seeing Autel highly recommended, I purchased this inexpensive unit. As a few other reviews mention, there is no instruction manual included. There is a QR code, but that only takes you to the Autel website, and lol, this product isn’t even on their website, so no manual or instructions. I did find a helpful YouTube video which walks through the process of using this and clearing codes. After watching that video, I was able to quickly find the code causing the check engine. Since the code shown related to a low voltage actually made sense based on using the vehicle to jump another car, I felt comfortable erasing the code to see if it comes back. This code reader did erase the code and in starting the vehicle, there is no longer a check engine light, woohoo. If there were instructions included or an actual website to reference, I would definitely give this 5 stars.

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.

The Autel OBD2 Scanner MS309 is an excellent diagnostic tool for anyone who wants to keep track of their vehicle’s health. It is very easy to use—just plug it into the OBD2 port and it quickly reads engine fault codes and checks the Check Engine light status.

Good quality

My friend said it's just what he needed. He said it works great and is easy to read.
