Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles

Sometimes checking engine lights is a task we easily ignore. This failure may be out of ignorance or just because it is now a routine that makes no much difference.

Some of us are content as long as the car can start and move from point ‘A’ to point ‘B’ and do not care much of what goes on under the hood.

From big auto motives to small cars with different engine powers, a simple check light may mean a lot when it comes to the engines mechanism how it works.

It is, therefore, important to be keen with these warnings and avoid disastrous situations.With the Autel MaxiScan MS300 scan tool.

Nothing could be easier than using it to check what that light on your dashboard means in a matter of minutes. With an easy design, its use is also easy in that even reading the codes on its backlit LCD screen is simple.

It Retrieves generic and manufacturer specific Diagnostic Trouble Codes (DTC) and displays DTC definitions onscreen.

Simple design

With two buttons, a backlit LCD screen I call this simple design. The design makes it easy to read, a menu with multiple language options and Diagnostic Trouble Codes definitions the scan tool is good to go.

Simple to use

The simple design is a major contributor to its being easy to use. Reading the codes comes easily to me since the screen has a backlight while in use. Even in the night, you will manage to read the codes easily.


This scan tool has an updated menu with multiple languages. This multiple language feature makes this device usable worldwide with all the onboard diagnostics compliant vehicles.

If you speak a different language, drive a different car from mine, it wouldn’t be so different if we used the same MaxiScan ms300 to check those check engine lights and discover our vehicles’ problems.

You can use it anywhere if you have it. You will not need an interpreter to do it for you as it defines those trouble codes too. Worth it, is it?

CAN and OBD II protocol compliant

The MaxiScan ms300 works with most OBDII-compliant; domestic, European and Asian vehicles. The OBD II protocol is standard on all vehicles sold in U.S. since 1996.

With most vehicle manufacturers improving and evolving with new models these modern vehicles are on-board diagnostics (OBD) compliant including those sold overseas thus this scan tool won’t fail you on that vehicle model you cherish.

It will be hard to come across a car that will not support this scan tool trust me. I have used it and not even once have I helped a stranded driver, and the scanner failed me.

Multiple codes

For all the time I have used the MaxiScan ms300, I am sure I still have so many codes in the scanner that I have never come across.

Not that it;s faulty but it comes with a CD catalogue of 7000 data trouble codes (DTC) with their descriptions. I know this is music to the ears because it is worth every penny having such a simple gadget do all this.


The MaxiScan ms300 is a small, mighty gadget but I assure you it delivers. Yes, it does so just like the huge expensive scanners. There might be no comparison at all, but it does its work in a mighty way.
