  • 12v and 24v systems
Works great on my 2016 volvo 780 d13. Does regen, speed limit setting ,code reading and erase. Also I did injector cut off and compensation tests. Although on the back of the unit it says 24v input this tool works on 12 volt trucks. Great tool for the money.

  • Great for diagnostics and easy to use.
This LAUNCH CRP129 HD Heavy Duty Truck Scanner is very easy to use if you're a beginner or have used similar devices in the past. We have a large diesel work truck and while I can't perform all the things that can go wrong, with this device I can save a lot of time and money when things are minor. Our situation typically requires a mechanic coming to us which can be quite costly so being able to diagnose simple things can be a huge help. I ran through a few tests and everything was fairly accurate. So far I haven't had any issues and I imagine it will pay for itself in time. I could see it especially being helpful if you have several large work truck, dump trucks, semis or are a mechanic on them. My only complaint is for the money I would have liked a bigger and better screen. I am also not sure it exactly matches the listing since that screen seems larger in the photos. It does seem durable though which is good news for a job where things get banged around. Nonetheless mostly happy with this. ... show more

  • Started off great
It was working fantastic when I first received and updated. But after a few weeks the last few trucks I've hooked up to it has not read or scanned going to hold out hope. The only fact I didn't rate it lower is that it saved me a trip to the shop when I originally ordered it
