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

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 with real-time data. This scanner is AWESOME!
