2021 Model - LAUNCH OBD2 Scanner CRP123 - Engine/ABS/SRS/Transmission Diagnostic Scan Tool SRS Code Reader with Free Updates Review

The LAUNCH CRP123 OBD2 Code Reader proved to be a very useful device. I have used on Ford, Dodge, Nissan, Honda, Volvo and Infiniti. This product saved me money on repairs and took a lot of the guesswork out of it.

I have this airbag light reset device on my 2011 Volvo S80 that the dealership was asking $150 to turn off. He did it with no problems and was very easy to do. It also works with our Mercedes E350, Lexus ES350 and Chevy Traverse. It was a great value and paid for itself after one user. It's very worth it.

More than just a code reader! Graphic PID, data recording and playback, freeze frame data for these intermittent problems. The full color display is great for plotting multiple components and makes it easy to monitor each component. I have had several Launch C Reader products. That's great. Ouch! Plus free lifetime updates!

I am a retired automotive engineer with 37 years of experience in the industry. I purchased this scanner and used it twice to diagnose problems with (1) my transmission and (2) the ABS/ESC braking system. Both times I managed to solve the problem thanks to the usefulness of this scanner. In addition to querying all controllers and sensors, it provides real-time data that can be observed or recorded while driving, and that is very important. User can read error codes and then identify problems…

Launch has developed a very complicated process to update the reader. First you need to find the right website. You then have to go to a non-intuitive website to find the right product and download the right update app. You then need to register to receive a registration code (presumably your registration password). You then start the update application by entering your product serial number (on the back) and your registration code. It didn't work except for me. I just get an error saying my…

I have been an ASE certified technician for 18 years. I've used the Launch line of products before. So I was able to buy these with a lot of confidence. It lives up to its reputation as a good quick scan tool for diagnosing both complex and simple repairs. Trouble codes don't tell you what's wrong with the car, they just point you in the right direction. And diagnosing your car is all about narrowing down the search. This tool gives you the ability to do that not just by extracting the codes…

I import repairs and sometimes I need a scanner to quickly diagnose OBD II cars because the more complex ones I have were $1500-3000 each, slow but extremely thorough, with many features that make it particularly useful. However, the CRP123 interacts incredibly quickly with the car's computer and can perform diagnostics on par with expensive scanners. This scanner is especially useful when a customer wants to know what to expect when they bring their vehicle in need of a scan to give them a…

I've needed a scanner for many years, but I was always able to borrow one from a friend of mine. Your scanner was only a few years old (in fact it was new) but it could only read engine codes. My hand was forced when my wife's 2006 H3 Hummer started behaving due to transmission issues. After researching different scanner brands and applications, I found that the CRP123 best suited my needs. The boy was right! After the H3 I used it on my Ford pickup to diagnose an ABS problem, then on a…
