OBD2 scanner devices have become very popular items for mechanics and dedicated car owners. The OBD2, which stands for Onboard Diagnostics II, is a standardized system that has been implemented in a wide range of cars and trucks, used by the onboard computer in the car for self diagnostic and reporting. Since OBD2 systems use the same communication protocols, codes, and connectors, it has become so much easier for car owners and mechanics to analyze a problem in a car. Brands are no longer a huge issue like before. Now, if you are looking for an OBD2 scanner as a companion for your car’s well-being, you are most probably considering either Launch X431 VII+ and Launch CRP123 right now. Which is the model that you should choose?
Design
If you put the two models side by side, you may see them as two very different things due to the colors. However, the looks are just the biggest difference between these two models. Launch X431 VII+ is black in color, whereas Launch CRP123 has a red body and a black center panel. Other than the colors, the two are very similar. They are about the same size, and both are compact, lightweight, and portable. These are the kind of devices that you can easily slip into your bag or the dashboard. They each has a nice color display screen, which is backlit so that you can easily read the information regardless of the light condition. The function and navigation buttons are mostly on the right side of the display.
Functionality and Compatibility
Launch X431 VII+ and Launch CRP123 have similar functionalities. They are powerful diagnostic utility devices; they both can work on both systems (ENG, TCM, ABS, SRS), and they both can read and clear codes on engine, transmission (A/T), ABS, and airbag (SRS). Both models also provide the DTC help and service, DTC reading and clearing displays, tests for oxygen sensor and carbon canister, as well as displays for the OBD2 Data Stream Graphic. Launch X431 VII+ and Launch CRP123 can be updated easily after getting registered. Updating the software is done via the website, which is only compatible for Windows XP and Windows 7 platforms. Both support various languages including English, French, Spanish, and Chinese.
Despite the similarities, these models happen to have slightly different compatibility. Launch X431 VII+ covers over 20 main car models from America, Europe, and Asia Pacific regions, but Australian models are not supported. Launch CRP123 supports some Australian models.
Launch X431 vs CRP123
In general, Launch CRP123 makes the best way to go due to the wider range of compatibility. It supports some Australian models, whereas Launch X431 VII+ doesn’t. Other than that, and the colors, they are similar.
