  • This is an Overseas Model so good luck with support
Color: black
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.

  • Works as advertised
Color: black
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. ... show more

  • This thing will keep you informed about your car.
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) ... show more

  • A good OBDII scanner at a nice price.
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. ... show more

  • Either it does not work with Toyota (2010) or it doesn't work as in the manual
The reader hooks up to my Toyota Sienna (2010) fine and it immediately powers up. The start menu shows up; but diagnosis does not proceed as in the manual - there is no option to select the make of the vehicle to reference the error codes. It reset the warning lights (VSC, Check Engine) fine; but no further diagnosis seems to be available. I am returning the reader and will reorder one that's JOBD-compliant. I don't think the description (even on manufacturer's website) is clear what (if any) Japanese manufacturer(s) it can work with. But this is an upgrade to the old DOS-PC-based OBD reader I have been using! ... show more
