But this LAUNCH scan tool also performs reset services (the CRP129 does not) for your TPMS and Throttle Adaptations as well.

The Bottom Line

All three models we’ve looked at from the CRP129 LAUNCH scan tool series all feature a similar design and quality. And while there may not be many differences in what they do, those differences are critical in deciding which product is right for you.

If you need TPMS features, you must use the CRP129E or CRP129X. But if you don’t want to fool with a touchscreen while relying on a tire gauge to measure your TPMS, then the CRP129 is best.

Those who want a basic understanding of problems with your vehicle will prefer the CRP129. But DIYers will want the CRP129E and CRP129X with their multiple systems and advanced diagnostic reports. And if you need the tool to perform system resets, do not purchase the CRP129 LAUNCH.

No matter who you are, make sure you do your research to ensure the scanner you buy performs all the functions for the vehicles you need it for.
