Not a bad scanner for the price. It works well on Allison, Cat Cummins. Wabco depending on the year it will work just have to use another function for it to work on them. Will regen and reset filter life. This is an over seas model so tech support is a little difficult.

Note: Photos taken with an iPhone SE. I needed a new ODBII scan tool for my vehicle, as the one I had was a basic 3 line/text monochrome screen with a green backlight, and the code information was a separate physical manual that you had to thumb through. I'll get to the cons right away: --Short cord; could be a foot longer. --No case comes with the device, you have to buy it separately. --Firmware update tool is only available on Windows PCs, no MacOS support. Pros: --Easy to navigate the menus --Responsive and clicky buttons --Powers on very fast --LCD Screen is 320x240 so it's able to display a lot of information that is accurate Some of the functions and capabilities only work on certain cars. For instance, my Kia Soul 2012 doesn't support some of the advanced EVAP tests or O2 sensor tests. The device was able to clear 2 CEL (Check Engine Light) codes that were bugging me, mainly due to EVAP issues relating to fuel emissions, which wasn't hindering performance or anything. Overall, I'm satisfied with this purchase as it wasn't too expensive and offers a lot of information that my old one did not.

This scanner works great on my 2013 Freightliner Cascadia. Takes some time to get familiar with it like any electronic device. I was able to code the new injectors I installed, run cylinder compression test and cut in/out cylinder function to diagnose the problem and erase all trouble codes once the work was done. It did everything I purchased it for and I definitely see this coming in handy down the road. I gave it 4 stars instead of 5 because its processing speed is little slow and its not Bidirectional but being able to perform Dpf services, coding and speed adjustments with a unit at this price point, I can look past these minor flaws. I dont see nothing wrong with this unit for the owner op that just needs to get a little further into depth to get to a problem and get up and going.

This is a great tool to have. i have an older car, and i took it to the local mechanic and they charged me $65 just to tell me what was wrong with the car ( called an inspection fee). i was upset, because $65 seems ridiculous which it is, and then i started to research to find out. An OBD2 Scanner can tell you pretty much everything about your car. So i got this scanner less than what i have paid at mechanic shop. Now to pay it forward, i have told all my friends if you ever get that deadly "CHECK ENGINE" light on your car, instead of taking to mechanic and bring a beer and ill tell you whats wrong. it is fairly easy to scan and you can punch in the code in this little gadget and it will tell you what is exactly wrong some time its very minor thing which if you are a little bit handy you can do it yourself. if you are not handy atleast you will know that oxygen sensor is $50 instead of whopping $350 at mechanic shop ( again i know that $350 includes labor too but its fairly easy you can youtube it)

This Code Scanner was easy to use. The scanner gave good information to help diagnose the cause for the check engine light to be illuminated. I like the fact that it gives the real time data stream while the engine is running. Clearing the code is simple, this scanner even asked if you want to proceed to clear the code when you choose that option. This scanner helped me determine the cause of my check engine light being on and how to correct the issue. It also has a code library, so you don’t have to go online to determine your fault code. It seems to be a nice product.
