- KONNWEI KW310 OBD2 Scanner Full OBDII Functions 10 Modes Automotive Engine Fault Code Reader Scan Tool for All 1996 and Newer Cars (Red)

The product is of excellent quality and as described, Showing Live Data, Reading Codes and Erasing Codes but unfortunately, the (O2 monitor test, Evap Leak Test, review data, On Board mon Test) feature is incompatible with my Chevrolet Optra Magnum 2008 model. It does not work as required, so I couldn’t use it. This may work perfectly for other car models, but it didn’t suit my specific requirements. No complaints about the product itself, just a compatibility issue.

The Product quality is poor, it didnt even power on, Product has manufacturing defect and is not compatible with Indian cars, do not purchase it as no replacement and refund is offered. Amazon is selling it as it has a stock of these scanners.

1. All code no remove 2. Easily usable 3. Any code not detection 4. Value of money

Nice product and worth it I have buyed it nealry at a price of 1900 and compatible with Hyundai and Honda, worth the money you spend

Sadly this product cant run diagnostics i.e read Error codes in Fiat models. Other functions like live data works seamlessly.

Excellent product works as expected. Total value for money at this price point. Kudos to the manufacturing team.

Got it at ₹ 1899 . Works on almost OBD2 cars, but not linked with 2007 and older maruti cars. Tested on 2012 swift and it did the job well. Also on hyundai i10. If you are willing to buy cheap but usefull gadget for workshop, go for it. It detects DTC easily and links with vehicle automatically,no need to put vehicle make or VIN. Detects DTC, can erase codes, shows upto 31 points of live running engine data. From me full 5 stars.

Doesn’t work it’s showing No fault codes in Maruti Swift

I needed this tool to troubleshoot OBD2 codes in multiple cars. The price was right and it had all of the features I needed for my wifes 2014 Hyundai Sonata. The menus are clearly organized and easy to understand. The green backlit screen is extremely easy to read, even in direct sunlight. The unit has live data monitoring capability which is also very useful. With only 4 buttons it is very easy and intuitive to use. The built in OBD code lookup database is a really nice touch. You can enter any code and get a full description right from the menu, which has already come in handy multiple times. I would highly recommend this unit for a compact tool to leave in your car and instantly troubleshoot problems!

good product , did the job well, instuctions were hard to read too small

The dreaded SES light came on the other day and my gauges on my vehicle are not working so I was in need of a way to see what the issue is. I have a fancy tablet style scanner from Foxwell but for some reason it wouldn't link to the OBDII protocol of my Mercury Villager last time I tried to use it. I couldn't find it this time around so figured a cheap basic OBD2 reader will do. This reader is pretty basic but does all the functions you would expect from OBD2 standard. You aren't getting advanced features here as those are more geared to the $200+ scanners. This one on sale cost me less than $15 and as you can see from my screenshots, shown me what I need to know. The neat thing is too this scanner has a built in code library so you can manually look up a code and get a description of the issue. I've used the Bluetooth reader from this same company and it's amazing. Mine was stolen so I have to get another but I can't recommend this model KW310 enough if you just need a basic obd2 reader on the cheap!

For the price, this is an OK unit. It does all what it promise to do, can check code, read code, erase code, and show IM readiness status. It is slower than other unit that I have. It takes like 5 to 8 seconds more to load up and connect to the car computer. If you see my attached picture, there is a typo on the error code. It misspelled performance. Hopefully, they will fixed those typos when they put out a new version. Overall, it is an affordable tool that does the job if you don't mind it being a bit slower and having some typos.

Absolutely 100% must have for us ladies who hate to take our car to the shop! This is the easiest, and at a perfect price way to ensure that we won't be taken to the cleaners by a machanic who assumes that just because we are female we don't know much in the way of cars. This product will save you and I mean male and or female hundreds of dollars. This eliminates- diagnostic fees, labor fees, and with it providing the library of code meanings you can even purchase the parts that are required prior to taking it into the shop which saves the upcharge cost of part that you would pay if the shop orders your parts or if you have a car savy guy or gal who can actually do the repair for you then you won't even have a shop bill at all. Trust me check engine light can be 101 things but alot of them can be resolved without even stopping by the garage let alone having garage repairs bills. All because of this Konnwei Kw310 code reader. Oh and by the way it will even clear the codes (turn off the engine light) after repair is made though otherwise it will come back on due to the original alarm code. Easy to use all in one code reader and clearer with code explaintions on device (no need to google search code meaning) including o2 sensor evap smogg data, stores live, playback data. All that included for a great price this is a must have for every car owner for sure..
