OBDLink® LX is a budget-priced, pocket-size Bluetooth OBD-II adapter for all OBD-II compliant vehicles (except hybrid or electric vehicles). It can be used as a diagnostic scan tool, trip computer, logger, and real-time performance monitor. OBDLink LX surpassed performance in every competing Bluetooth OBD-II adapter, delivering 300% more data samples per second. Its BatterySaver™ sleep mode allows the adapter to stay plugged in continually, without draining the vehicle’s battery.

OBDLink LX’s support of the de facto standard ELM327 command set, makes it compatible with tons of third-party OBD software and mobile apps.

OBDwiz and OBDLink app, included with OBDLink® LX, allow you to:

  • Turn off the check engine light, and erase stored diagnostic information
  • Read and erase stored, pending, and permanent trouble codes (both generic and manufacturer-specific)

Worked to stream OBD data to a tablet ion our ...Review by hans [Amazon Review]
Worked to stream OBD data to a tablet ion our Chevy. cost is minimal and with the use of a free app am able to check codes and view real-time data while towing. Leave it plugged in 24/7 without issue and no battery drain (Posted on 12/1/2016)
So far so good!Review by JAH [Amazon Review]
The device is simple and easy to use.

I like that dashboards and displays can be customized to the information YOU want to see in digital, analog, large or small displays, etc. I imagine the available data depends on your vehicle, I have access to more information than I could possibly care to know about the car. I had to pair it twice before it connected but haven't had an issue since.

Vehicle speed is spot on. Other things like fuel level and temps are spot on as well.

Some of the app calculated values aren't very accurate.

I bought this as a toy mostly just because I can set up my phone in the car mount and display more information than I would be able to on the vehicles gauge cluster.

The trouble code scanning is a plus but I have not used it to resolve any problems with the vehicle so I can't detail how well or accurate that is. (Posted on 12/1/2016)
Perfect. Easy to use plug and playReview by Martin N [Amazon Review]
Perfect. Easy to use plug and play. Clear several codes and saved a lot of money. Used this on a 2007 Xterra and 2004 Toyota Sienna van. (Posted on 11/16/2016)
Works GreatReview by MPatt [Amazon Review]
Great bluetooth ODB port reader. I use this with a Samsung Galaxy S7 and it pairs just fine. You can view all sorts of important information. Currently using it to log my CVT temperatures on my 2015 Subaru WRX. (Posted on 11/16/2016)
And this works great for meReview by [Amazon Review]
I'm a mechanic at big o tires woodland, ca. And this works great for me. We have a 15k$ snap on that does most anything. And this Bluetooth one will read 90% of what the snap on can. You can't turn anything on like the fan or fuel pump. But I can read codes, clear them, and check fuel trims, o2 sensors. Graph stuff. Even used it when our snap on broke for a few days. But remember to look up what device you have. Android or iPhone take different one device. (Posted on 11/16/2016)
It works great paired with the android appReview by bg [Amazon Review]
Used in a 1999 GMC k2500 suburban. Monitoring drivetrain while towing our travel trailer for big vacations. It works great paired with the android app. (Posted on 11/16/2016)
Works well and saved me money.Review by Phil [Amazon Review]
Works as advertised and allowed me to monitor the CVT fluid temperature on my Subaru Outback while changing the fluid (a requirement for this procedure). Used successfully with several of the free and paid apps for monitoring OBD-II bluetooth scan tools. (Posted on 11/16/2016)
this OBD is great and safe so can stay connected in the carReview by J. Bauer [Amazon Review]
This, compared to others seems expensive but don’t be fooled into buying cheap this OBD is worth the extra few pounds. It has a security button that needs to be pressed and once pressed connects straight away to my android device. I use the Torque ap to help with diagnostics and many other features, 0 -60 etc and because of the high transfer rate this works really well! Save a lot of money finding fault codes, this OBD is great and safe so can stay connected in the car. (Posted on 10/13/2016)
The adapter works great and easily links up via BT to my Galaxy S4 on Lollipop 5.0.1Review by speedlever [Amazon Review]
I installed this on a 2008 Honda Ridgeline (9141-2 OBD2 protocol) and it paired right up with no issues. I like the ScanTool app available on the Google Play store too. In addition, I also use Torque Pro.

I found that I cannot run both Torque Pro and the ScanTool app at the same time. The ScanTool app has a connect/disconnect button at the bottom of the screen. If I want to use Torque Pro after using the ScanTool app, I first have to disconnect using that button before running Torque Pro.

And if after using Torque Pro, I decide to use the ScanTool app, I have to quit Torque Pro, crank up the ScanTool app, and hit the connect button.

I find both apps to be very useful, so that's a minor hassle in order to use both. I only wish they could both be operative at the same time so I could flip back and forth between them. I don't know if that is a limitation of Lollipop, BlueTooth, or the adapter.

Regardless, I find the adapter to work and function as advertised. I am pleased with the product.

Note: The ScanTool OBDLink LX adapter replaced an inexpensive supermini ELM327 adapter (which also worked fine). The OBDLink LX is about twice the size of the supermini, but I have no issues with it interfering with driver legroom. (Posted on 8/15/2016)
Works, it's fast and very stableReview by Elisamuel [Amazon Review]
Works as advertised. The cheaper readers might be cheaper, but doesn't compare in regards of how solid and fast this device is. That alone deserves a consideration. There is very little to no lag when polling data from my car and displaying it.

To those concerned of battery drain, please make sure that your vehicle doesn't have other issues that could drain the battery. I've had the OBDLink plugged in 24/7 in my car and other than rough starts due to the cold weather, there are no signs of noticeable battery drain. (Posted on 8/15/2016)
I was a bit surprised at first just how easily this did connectReview by Amazon Customer [Amazon Review]
I was a bit surprised at first just how easily this did connect, and even more pleased at how it reconnects each time to either my tablet or phone.

The OBDLink app I personally found to be the best one for me, so that was a double plus. Overall I would highly recommend this. For casual user who just wants to scan and read diagnostic codes, or the enthusiast who wants to this running at all times, this product does its job perfectly. Furthermore, I never have had issue with Bluetooth connection, it has yet to randomly disconnect as I have experienced other devices to sometime do (i.e. BT keyboard for tablet, or BT headsets for phone) (Posted on 8/15/2016)
A must have vehicle scanning tool that will save you a lot of car repair money!Review by A. WU [Amazon Review]
This is the tool to get if you need an OBDII scanner. There is plenty of selections out there, but for an Android user like me, this is a perfect tool to work with. For Android, you can download the free OBDLink scan tool, but I haven't quite figured out how well the app supports multiple-vehicle profile. If you have multiple car sharing this one little tool, you can purchase Torque app on Google Play. Torque allows you to set up the vehicle profile once, and be done with it for life.

A couple things to keep in mind on what the tool can do for you. You can definitely use it to scan for faulty engine code, so you don't have to make a trip to O'Reilly's/AutoZone/AAP for engine code scan. In addition, you can reset the engine codes, and verify the issue after driving for 30 min or less. If you plan to get your car state-inspected, you will definitely need to drive your car for about 30 min, so you don't automatically fail the test.

Other neat feature includes real-time monitoring of the vehicle data, including but not limited to engine temperature. In fact, because of this tool, I was able to detect abnormal engine temperature while driving and took corrective measures (adding for engine coolants) before the car breaks down on freeway.

In all seriousness, within a week later, it detected a failed upstream oxygen sensor. Since I knew what went wrong, I was able to buy an oxygen sensor online and figured out the repair on my own. After that, the same vehicle passed Texas State Inspection. In all, I gained the knowledge on how to replace oxygen sensor and not have to throw money at a local mechanics.

This is a small investment that will save you a ton of headache later on. A must have indeed! (Posted on 8/15/2016)
Useful device but take your time setting it upReview by Gonzoman10 [Amazon Review]
Good scan tool, with nice features like sleep mode that make it worth the price.

Warning: please google search your vehicles profile and such to make sure you statically set your settings using the torque app at first use. I made the mistake of not doing this and have ran into problems. When starting the car the torque and the device begin scanning for vehicle information and hardware which would interrupt certain electrical systems in the car. I began receiving engine warning lights and transmission codes. Worried I took my car to a mechanic to have it checked. Fake errors, so just set it up right the first time and you are good to go!

Best ones out there.Review by Amazon Customer [Amazon Review]
Does what it says, and does it very well. The software it comes with might as well be beer coasters, works great with Torque Pro on my phone. Saved a ton of money using it on my car and friend's cars. This is my second, I had an MX model and lost it. Just had to get another one, and immediately saved more than the purchase price clearing a spurious emissions code. A friend got a couple of the cheap odd brand cheap ones (less than $15 each) both didn't last more than a week. ScanTool's keep working great. (Posted on 8/15/2016)
Awesome tool to have!Review by John [Amazon Review]
This thing is wonderful! It took a few minutes to get setup.. the quick start instructions didn't say I had to hit the little button on the unit to initiate pairing mode, but once I looked up the instructions on the website it was a piece of cake.

The included app is great and easy to use as well. It also works with both Torque and Torque Lite. This thing is going to save me tons of money in the coming years! It's already saved me a trip to the shop by telling me my problem is a bad o2 sensor that I can easily replace myself. Take that emissions! (Posted on 8/15/2016)
BANG FOR URE BUCKReview by Walt [Amazon Review]
Works great in my 2001 Jeep TJ. Took 2 min to connect. I leave mine plugged in all the time with no problem starting even after days of no use.

Worth every dolla if u tinker with ure rides....lol or u just want a new set of guages!!!! LOVE IT!!!! JEEP ON!!!!!!!! (Posted on 8/15/2016)
This is a wonderful tool whether you're a tech or enthusiast looking for ...Review by Beau Steward [Amazon Review]
This is a wonderful tool whether you're a tech or enthusiast looking for info for troubleshooting or improving things, or if you're just interested in what's going on, such as looking at fuel savings. It's mostly non-intrusive due to its size, and as long as the OBD2 port is out of the way, it doesn't interfere with driving. It works with its own Android software, or if you'd prefer, Torque Pro. Outside of a known issue with my car, I have run into no problems with using this device, only that I had to develop a habit to prevent further issues. The problem is likely with my car and not the OBDLink.

NOTE: I use this on a Scion FR-S. I don't know if this issue exists on other makes and/or models, but if you start your vehicle with Torque already running, it is possible it can trigger some error codes, and if it does, is likely to cause some ECU issues (ie: doesn't turn on one of the fuel rails causing drastic loss of power). The damage is not permanent. Turn off Torque (completely), turn off car, wait, turn on car, turn on Torque, reset remaining fault codes, turn off Torque, turn off car, wait, then start car again. Everything should be happy again. I have developed a habit of turning off Torque before I turn off my car when I park. (Posted on 9/25/2015)
Works WellReview by B. Gideon [Amazon Review]
This works really well. I have no problem syncing it with my Samsung Galaxy Note 3. I have tested it on a Ford Escape Hybrid and a Ford Fusion Energi using the FORScan app in the Google Play store. It was able to read all of the HSCAN modules including those hybrid unique components. (Posted on 9/25/2015)
Just what I needed.Review by Tim
For some reason, my car does not come from the factory with coolant temp or boost gauges (yeah, it's S/C'd - go figure). The OBDLink LX allows me to monitor all important information from one screen. I love it! (Posted on 2/1/2015)
Amazing Product!!Review by SCOTT
The product meets and exceeds all of my expectations. It was easy to set up, fast as lightning and just works fantastic. I promise I'm not an employee, just a very happy customer! (Posted on 9/4/2014)
