Saving money through this method will benefit you
5/5

In order to fix the fuel cap light and check engine light on my wife's 2015 Jeep Cherokee, I took it to my local auto parts store and they sold me a $15 part. I spent more time dealing with the parts store than I would have with my KONNWEI KW310 OBD2 Scanner, so I went out and bought one. I discovered The correctly sized part, which was a Fuel Vapor Leak Detection Pump, was purchased and the issue was resolved. I did not have to go to the store for this tool, leaving me with lots of savings.

Useful and high-quality OBD2 scanner tool at a very low cost
5/5

Using this tool, I was able to troubleshoot codes from multiple OBD2 systems on I bought it for my wife's 2014 Hyundai Sonata because the price was right and the features were perfect. There is a clearly arranged menu, with backlit text so that you can see it even in direct sunlight. The green screen is extremely easy to read indoors and outdoors. Besides live data monitoring, the system also has a built-in clock to display the time and date. The only buttons you need to push make it very intuitive for anyone I think the built-in database for OBD code lookups is a really nice feature. The option to enter a code and get a full description is right in the menu, so it has already proved useful on several occasions. If you are in need of a compact tool to leave in your car and instantly troubleshoot problems then this is a great option!.

I am very pleased with the price and the easy to use gadget
5/5

As a result, my new (used) truck would keep coming up with a check engine light, even after I reset the engine. I was tired of going to the auto part store to get the part, and this did exactly what I was looking for. It turns out what I need to fix has already been found, and now I can use it with my friends. I thus found it to be a good value and a good purchase It was accurate, the same codes ran the same way the auto parts store did. It's okay to wait until I have major issues that I cannot resolve on my own to visit the dealership. This tool has a great price and is a great value.

Result of diagnostic test that is clear
4/5

It's really great to have it and at such a great price. I feel that it's a must have for any woman who knows about cars and engines. I would recommend it to anyone who is interested in cars or engines. This code reader was specifically bought for my Mercury Grand Marquis limited edition 2005, in order to diagnose some issues that I thought were occurring, and to distinguish between the battery and the alternator I didn't want to just replace both of them when the fault lights began flashing. It gives me more confidence about the vehicle I'm driving now. I feel like you won't have to take me to the cleaners on any further diagnosis, or I won't have to pay anything unnecessary. I firmly believe this is a tool that nobody should be without, and it's at a fair price as well.

I like it
5/5

Konnwei products were previously used by me, and I once had an upgraded model before it was lost. My car's OBD codes needed to be cleared, so I bought the product. As expected, the tool performs The live data aren't as real-time as they could be, but for the price point and the objective, it's not as bad as it can be.

A must have for your collection that delivers a great deal of value
5/5

For those of us who dislike taking our cars to the shop, this is a necessity! In order to ensure we won't be taken for a ride by a mechanic who thinks that just because we are female we don't know much about cars, this is the easiest, and cheapest, way to ensure everything will go smoothly. You can save hundreds of dollars if you use this product, and that goes for men and women alike. In this way, you can eliminate- You can even purchase the parts that are required prior to taking the vehicle into the shop, which saves the shop ordering cost of your parts or you can even have the repair done by a mechanic who knows the way around cars so you won't have to pay a shop bill. If you ask me, there are 101 different reasons why your check engine light is on, but you can often take care of them without even having to visit the garage, let alone having to pay for any garage repairs. The Konnwei Kw310 code reader is responsible for it all. Additionally, the unit can also clear the codes (turn off the engine light) after the fix has been made, otherwise the light will soon come back on due to the original alarm. The reader is very easy to use, and it provides detailed code explanations on the device itself (no need to google the codes meaning), as well as data from the oxygen sensor and engine exhaust, as well as live and historical readings. The fact that it includes all this for such a low price makes this a must have for every car owner.

The quality and price are excellent! The software is easy to use as well
5/5

It is of excellent quality and at an excellent price. As well as being able to navigate the features of the device, it was very easy to use. I used this program to check my car's engine and clear its CEL codes fast. Knowing what is the real issue before making parts purchases allowed me to avoid being ripped off by shady mechanics and saving me a great deal of time and money by not going to the dealer or auto parts store. I highly recommend this tool and think it is a must-have.

5/5

are becoming less informative and have been replaced with warning lights instead of gauges, showing a tendency towards reducing information available to drivers. As a result, now when there is a warning light, there is no clue what is You can bridge that information gap with the help of this tool. Plugging it in and using it are easy. I enjoyed the instructions because they were in-depth and clear It is better to have on-line tutorials. In less than a minute, I was able to figure out what was going on. It is imperative that you use the internet to help you understand both the codes and the.
