OBDLink WiFi is our latest, most advanced scan tool that supports all OBD-2 compliant vehicles. In addition to operating wirelessly via WiFi, it includes a built-in USB interface.

OBDLink features the industry-leading data throughput to capture more graph points and faster screen updates.

The free feature-packed OBDwiz diagnostic software (for Windows) included with the scan tool allows you to:

  • Turn off check engine light, and erase stored diagnostic information

  • Access freeze frame information
  • Display, graph, and log 90+ real-time parameters
  • Create custom digital dashboards
  • Measure and display fuel economy
  • And much more!

Premium diagnostic software, such as ScanXL and ScanMaster, offers a myriad of additional features including Dynometer, multi-language support, and data manipulation tools. ScanXL’s Enhanced Diagnostics Add-ons offer support for thousands of enhanced manufacturer-specific parameters, as well as ABS and other proprietary systems.

Can't even read codesReview by Josh
Tried it on a 2007 ford fusion, can't even read the codes, says I need to buy an add on. Cant read toyota tacoma 1999, or a toyota tacoma 2006. I wouldn't recommend this hit or miss product. Spend some money and get a quality tool, not one of these novelty items
--Feb 10, 2014 4:47:35 PM

RESPONSE: You can always write us when you have questions like this one. The fact that you couldn't access the codes you wanted is not the fault of the scan tool. As long as your vehicle is OBDII compliant, any of our scan tools (with the free software provided) will read and clear all the basic OBDII trouble codes listed at this link: http://www.scantool.net/obdwiz/#supported_pids

To access anything beyond that, you would need to invest in vehicle-specific software. For example, in the above link, you will not see things like ABS or SRS, A/C or Airbags because they are not required by the OBDII standard. We do carry this enhanced software for GM, Ford and Mazda only.
**You should be aware, that once you move beyond the OBD2 basics, there are no requirements for the manufacturers so vehicles do tend to vary widely. Some vehicles will not allow access to certain parameters, it all depends on the design of your vehicle.

worksReview by fixkick
it does not work on many (vast) non usa cars.
it will not work on OBD1 old cars, pre 96
and pre 2004 in some countries. even canada went OBD2 in 1998.
do not buy the tool if you dont live in the usa,
but do first find out what your non usa car uses.
that be first.
how about jan 2006 cars in Australia.
non compliance before.
many pre 2003 Eurpean cars are not compliant.


OBD2 is a USA idea, and invention.
other countries use it or not, or abridge it.
OBD2 or EOBD compliant.
the mitsbishi fusco canter, is a huge truck
and is sold in the USA, are you?
At 17,995 lb./25,710 lb., the FE180
and truck rules are not the same as gas passenger cars, not at all.
and diesel rules and gasoline are different on heavy trucks. 14,000 lbs is the magic weight.
over that. and different for these with alternative fuels, state country, state engine and type and fuel options, posted under the hood. The heavy trucks have complex rulings by EPA. why over this little box.
2010 is a new cut in year,
ask todd here for help.

Didn't work for me...Review by Owen
I bought this unit in the hope that it would read the ECU data from my 2010 Fuso Canter, but it didn't. The unit seems to receive data from the truck, but the software reports that the ECU is not OBDII compliant. I am pretty convinced that this is a software issue, not a hardware issue, but when I asked the question I was just referred to the link given in the first review. That annoyed me a bit I must say. Surely the guys who build these things should know if they will work on a specific vehicle or not. Not a happy customer.

RESPONSE: Unfortunately, we do not have a list of which vehicles will or will not work with our scan tools. What we do know is that any vehicles that are OBDII compliant will work with any of our scan tools. It is not a hardware or a software issue, its a compliance issue. Small cars and trucks manufactured here in the US are required to be OBDII compliant as of 1996, but as for others many are just not. We do offer a 90-day money back guarantee. You can email us if you are interested. (Posted on 11/21/2012)
Fair productReview by Joseph
The tool work with some vehicles. I've tested it on 2003 Hyundai Matrix (worked), 2002 VW polo (worked), 2006 Renault Megane (only some functions worked), 2002 Toyota RAV4 (did not work), 2009 Nissan 350z (did not work), 2010 Toyota Avanza (did not work)

RESPONSE: All of our scan tools, like most generic scan tools, are not compatible with OBD-I vehicles. The article on the following page can help determine compliance if you are unsure: https://www.scantool.net/support/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=2&nav=0,1

Works amazingly well as advertised.Review by Andre Sahatoo
This tool has worked in every vehicle that I have tried it in so far (Nissan, Toyota, Mitsubishi). Key features are it has life time updates to the firmware, WIFI is great for eliminating cables, works on PC as well as my Ipad and Iphone with (Dash Command app). This is definitely a good scan tool for any.

Beats the competition hands down!Review by Joseph Hoffman [Amazon Review]
I love this tool, it has more options and features than I would use as a mechanic. Mostly I use it for diagnosing problems with cars in order to fix the correct problem. Free updates for life and wireless connectivity are just a few options that make this tool worth it's weight ( or lack there of ) in gold. For the price you could get a hand held tool for the same price or more. Or you could get a tool that does it all for a very, very reasonable price! As soon as I found this I knew it was what I needed and wanted. Thanks for such a great product!

works well Review by DD
Does what they say it does. I haven't used it with an I-phone yet but I can say it is great with a lap-top. Diagnosed my mothers Camry to a specific cylinder. And my brother-in-laws Dakota. (Posted on 5/22/2011)
