BLCKTEC410 Bluetooth OBD2 Scanner Diagnostic Tool - Car for All Cars OBDII Compatible Check Engine Light Code Reader with Reset Comes Premium OBD App On iOS & Android

I’ve worked in the automotive parts industry for over thirty years and then another ten years at an automotive repair shop and this tool is great!I’ve since retired and my wife Kia check engine light came on and it was also due for inspection for looked a cheap code reader. The first one was junk and then I got one and it delivered the information I needed to correct the problem myself and cleared the light and had a clean inspection. A few months later the check engine light came on and the car was running rough so I checked with this code reader and found out it was misfiring. After replacing the spark plugs and cylinder one ignition coil the car ran great! Got all the parts here for a good price too.The device works so well with my cellphone and gives you live data which is a huge benefit

I thought at first they had forgotten to put the reader in the package. It’s tiny but loaded with features. Easy to connect and set up. Everything you need to know about your vehicle after the scan and it create a history file for access if you need it at anytime.

Nice device. The software on my Android gave me the details of the O2 sensors so I could tell the mechanic who wanted to replace them that they are not defective. That alone saved me the cost of a needless repair.

When reading through some of the reviews on this, there are a few that talk about connectivity issues, and I've discovered that it might not be the reader but the car. I drive an older Lexus that has some quirks that pop up every couple months and had gotten tired of crawling under the dash to plug in my old reader. Well, I started having connectivity issues and it annoyed me to the point I got out my old reader and plugged it in to clear the codes, well, I decided to just leave it plugged in as it usually quirks a couple days in a row and then goes away. That's when I noticed something, the reader was laying in the floorboard and I could see it as soon as I opened the door and it would power up as soon as I opened the door, before I touched the start button. So, I tried an experiment the last few days, I would start the app as I was walking toward the car, before I touched the car. Sure enough, it would connect every time without issue and work perfectly. I'm thinking that with newer cars that have proximity sensors tied to the key fob, the car does a different "power up" than older cars and this is what is causing the issues.

Muy bien

I figured this device would at least stay paired with the phone. You know how you get a $5 bluetooth speaker and you turn it off, turn it on, and it automatically connects? Not with this waste of cashSo you gotta plug it in, sit there for the sluggish app to find the device, pair the device, then input the vin/year make model EVERY. SINGLE. TIME.Also, I assume due to its hipster bluetooth functionality, your vehicle must be in accessory mode. I've never had any problems plugging my $15 autel on any of my three vehicles while they are running.I got this for road trips, interested in the live data so I could see exactly what my car is reading instead of going through a list of probabilities which causes a dummy light, throwing money at a problem.I haven't even had my CEL come on since I bought this, but I guarantee I would not reach for this pos - pull over, turn off my vehicle, sit on the side of the road for at least 180seconds, then continue down the road. It wouldn't be a waste of time, but dangerous bruh.I'd reach for my $15 scanner, and worst case scenario Google the code to find out the most popular cause.In conclusion, I would not recommend this. However if you like pitter-pattering, wasting time staring at your phone, for some reason havent memorized troubleshooting codes AND can't use google to lookup said code, I'd say this product is great for you. I mean live data works, and so does recording live data. But still, PITA. 1 star.

I love it. Compact and light. App works great!

Good news is it read the correct code. Other good news is it will reset the code. Not good with instructions so you got to figure out when the vehicle needs to be cranked and when the vehicle just needs to be switched on. When giving possible solutions it only gives one. I've had other code readers like this that would give possible solutions by percentage of what has fixed the code. In the first case it told me it was my evap canister purge valve. But in reality it could have been the canister itself, the canister solenoid, The Purge valve, The temperature sensor, a bad vacuum line, or the wiring harness. For The price I'll do some research and some testing and really have no complaints.
