3 Hottest Reset Services, Get Most-Common Repairs
Based on extensive user feedback and relying on years of technical expertise, LAUNCH has integrated the 3 most-frequently used service functions (in US market) into this car scanner. So this OBD2 scanner is your more cost-effective option as you can avoid unnecessary visits to dealerships.
- Oil Reset, the #1 Service Car Drivers Need in U.S.
Oil reset (oil change reset, or oil life reset) is crucial for car drivers because regular oil changes are essential to maintain a vehicle's performance, prolong engine life, and prevent costly repairs.
With CRP123X Plus, you can easily reset the oil change indicator after an oil change or maintenance service; turn off the "check engine" light or the reminder that appears on the dashboard.
By doing this common service on your own, you can only pay for the materials used for the oil change, saving 10~30 bucks around.
- SAS Reset, Let Steering Angle Back To Default
SAS reset is used to reset the steering angle sensor back to its default position after steering-related repairs (e.g. wheel alignment or suspension work). If not reset, it can lead to compromised performance of car safety systems, resulting in unsafe driving.
This cost-saving can range from around 50 to 150 bucks or more.
- Throttle Adaptation, Calibrate Throttle Control System
Throttle adaptation can relearn the throttle's operating parameters and restore optimal performance, because over time the throttle system can develop issues like throttle lag, poor acceleration response, or rough idling.
By doing this reset service independently, car drivers may save from 50 to 200 bucks instead of asking for mechanic’s help.

Bought this launch scanner to have it for emergency’s but it’s my favorite tool compact fast long battery to many features to name I recommend it could save you from buying a bad car
Great product that is easy to use and comes with a carrying case. Purchased to troubleshoot a few issues on a newer diesel truck along with being able to trigger a regen on the exhaust system. I would highly recommend due to the ease of use and clear display.
This is a gift I bought for my dad and this is his impression/opinion on it.This will save me a lot of money instead of taking my vehicle to a mechanic, the launch CRP123X Elite is perfect for anyone. Feels very high-quality! The big rubber over mold around the device help when holding it. It is mostly plug and play, it has a rechargeable battery which is nice, so you don’t have to be plugged in to be able to turn it on. It comes with a nice case, thetouchscreen on it is amazing, it's just like using your phone and also very user friendly, if you don’t want to use the touch screen then you can use the buttons instead.Other useful features are the code search. If you're connected to the internet through wifi, when you do the code search it brings up Google search just the same way it does on your phone, it will also save the vehicle information and codes for future use. If you're unplugged and away from the vehicle, but want to look at the codes just power it on, and find the file. The auto vin detect is also great, I highly recommend it for anyone who wants to work on their own vehicles or know what is wrong with it first before taking it in to a mechanic.
Having worked with various scan tools over the years, I can confidently say this device stands out for its speed, reliability, and user-friendly features. I initially purchased it for quick diagnostics across multiple vehicles, and it has consistently delivered excellent performance.One of the standout features is the Auto VIN search, which streamlines the identification process and saves valuable time. The live data function is highly responsive and accurate, making real-time diagnostics smooth and efficient. The touchscreen display offers sharp definition, enhancing usabilityA colleague of mine also used this tool to diagnose a persistent issue in his vehicle, and it proved instrumental in identifying the root cause quickly.Overall, I highly recommend this scan tool for car enthusiasts seeking a dependable and fast diagnostic solution. It offers excellent value for the money and is a worthwhile investment for anyone serious about vehicle diagnostics.
Great device very handy for situations where you don't know where the problem is coming from it really helped figured out the issues with my car was able to remove the codes and fix the right problem on the car very good for the price
