Launch CRP129 OBD2 Code Reader Review

The CRP 129 is the latest model from Launch, a company that has a reputation as one of the leading manufacturers of OBD2 scanners. This model blurs the lines between a professional scan tool and a code scanner, with such features as service reminder reset, and the ability to graph and display live data for ABS and SRS. The scanner also offers the fastest DTC clear and read functionality around. Just like with other models of Launch code readers, codes that are manufacturer specific are built right in. You’ll also love the troubleshooting feature that lists the main causes for trouble codes. This feature will help you to tackle the job correctly the first time around. Other top features include free updates and the ability to print diagnostic information.

With so many functions to choose from, it comes as no surprise that this product is marketed more for the pro mechanic and experienced home mechanic than the novice.

129 Code Reader Conclusion and Rating

The 129 does offer many of the same features that pro level models have, but the device is seriously lacking overall usability for beginners. If you’re not a mechanic, then you’ll definitely have trouble navigating the user interface or even understanding the diagnostic process. Fortunately, the Launch customer service team has a reputation for quick responses and helpful feedback, but if you don’t have any experience in the garage then this model may be more than you can handle. However, for the price, this device really does deliver in terms of functionality, and its ability to reset a wider range of codes. The included database will be helpful for users of all experience levels.

A great buy for home use for the experienced do-it-yourself mechanic, this is definitely a scanner you’ll come to rely on in the garage.

Consumers who purchased this model gave it a rating of four out of five stars for the vehicle database, the wide range of functions, the free lifetime updates and the overall quality of this OBD2 code reader.
