  • Already paid for itself, great value if you're the inquisitive type
Style: SC301 Black
The machine itself takes some time to understand if you're unfamiliar with odb2 codes. The manual isn't particularly clear but I was able to manage. You basically have to set your vehicle in it's memory and then it will pull the relevant codes for your systems' computer modules. Once those are in place you can run a scan and it will show you the problem codes. There's a bit of a description in the machine, but it's easier and more complete to diagnose with a search engine because you can usually find the exact or very similar case. This way, you also learn more about your vehicle's systems, which is great for me as I'm technically inclined but very new to car repairs. I bought this knowing it would come in handy someday, but my wife wanted me to return it given that there was no pressing need. I legitimately forgot (my return pile was moved during cleaning) and the return window passed. Shortly after that (as luck would have it) her 2012 Honda CRV engine light came on. That model is known to have issues with the gas cap. Specifically, the sensor has difficulty reading data and posts a "check gas cap" message to the dash display. This time, the odb2 code indicated a fuel evap problem. Knowing the former message was common I decided to replace the cap (~$16US for a nice-ish one) as a way to eliminate that as the cause. Sure enough the code cleared and no lights/messages for over a month. It has already spared us the cost of a mechanic's diagnosis, not to mention future potential of being swindled. For around $35 that's a no-brainer if you have the wherewithall and patience to work through some debugging. ... show more

  • NICE OBD II READER
Style: SC301 Black
Brand New tool received recently and has many features I'm still learning. So far, Control Buttons seem to be straight forward on functionality, has a longer cord than other readers, (very nice as I can sit/stand and troubleshoot) and the Live Run Feature,(cant wait to test that). I also bought the Insurance Package 'just in case'. I'll update as I go if any positive/negative issues,concerns ... show more

  • Can do a lot of things, but not all
Style: SC880 All System Diagnosis + 25 Services
I bought this scanner after getting a (new to me) 2004 Mercedes S500. This scanner at $250 is a great deal, and on most cars it does everything you'd need and more. However, when it comes to Mercedes there are many things it can do, but many things it cannot do. The main thing I bought this for was to scan codes so I could see if this car was worth keeping or not. It pulled codes from almost every single module, except SRS, which is impressive. When it came to fixing those codes that it had pulled it got a little difficult, this scanner does do what are called "services" on most models, it cannot do any actuations or specific testing. This means that I couldn't test each module to find the cause of my codes, the scanner was just basically telling me that some module somewhere has a fault somewhere down the line. Also most of the services do not work for my Mercedes, I tried the ABS bleed, transmission relearn, oil reset, and the SAS relearn/calibration, none of the services worked. However, I did try this scan tool on my 99 Ford Explorer and 2013 Chevy Impala as well, it read every single module and every service worked (at least the ones that the cars could support). Seriously though, if you have a specialty (especially European) car (Mercedes, BMW, Audi, Volvo, Saab, etc) do yourself a favor and buy that $400-600 tool you've been holding off on. ... show more

  • I could not get this to work!
Style: SC301 Black
I have a Toyota Rav4 2007. I plug it in, start the engine, and no matter what button I push (except power), this device scans the car and then displays a screen with a matrix of codes. As shown in 4-30 in the User's Guide on page 23. From there, no button makes changes the screen. I can get no other screen to show nor can I get any other menu screen to show up. I tried it on my 2018 Audi Q5 and it exhibited exactly the same behavior. I think this is either defective or totally worthless or both. Update: The company reached out to me for support. That showed good customer relations. I find that if the first thing I do after plugging in this device and starting the engine, is PUSH THE GREEN BUTTON, then things behave as described. I was able to identify my car's problem successfully. I have still deducted one star because the operations manual was insufficient to inform me of this when I read it. This in light of the fact that I am a technical professional and have authored numerous user manuals and product descriptions in my career. ... show more
