Key Differences

Launch CRP123E and CRP123X are twins with minor differences. The only difference between them is the design. While the Launch CRP123X has a physical keypad beside the 5-inch touch screen, the Launch CRP123E doesn’t. It only has a 5-inch touch screen.

Key Similarities

1. Full OBD2 Diagnostics

Based on our tests, we discovered that both the Launch CRP123E and CRP123X can do all 10 of the important OBDII tests. They include reading error codes, freeze frame data, live data, AutoVIN, on-board monitor diagnostics, EVAP test, I/M readiness, O2 sensor test, etc. These are all really important functions for an OBD2 scanner, and we were happy to see that they worked really well on all the cars and light trucks we tried them on.

2. Four-system Diagnosis and Battery Test

Utilizing the Launch CRP123E and CRP123X, we can perform comprehensive diagnostics on the engine, ABS, airbag, and transmission systems with ease and uniformity. In addition to reading and clearing trouble codes, these scan tools provide an extensive array of live data, facilitating the precise identification of system issues. Furthermore, the battery test function proves valuable and operates seamlessly during our testing on various vehicles. The data obtained during our evaluation is presented in the table below:

Note: The results were consistent across all nine vehicles tested.

3. Oil Reset, SAS Reset, Throttle Adaptation

The three reset functions are designed for home mechanics and both the scanners work the same in our tests. No significant differences found.

4. Wide Vehicle Coverage

The two Launch scan tools are compatible with all the 10 cars and trucks we tested. However, it doesn’t mean that they will work on any vehicles. It’s better to double check using the vehicle coverage checker provided by Launch

5. User-friendly Build, Strong Configuration

The Launch CRP123E and CRP123X are well-designed scan tools with user-friendly build and strong configuration. These compact car scanners feature a sleek and durable design with an easy-to-navigate color screen. 

They both come equipped with a robust OBD2 connector cable for quick and secure connections to your vehicle. 

Their intuitive interface allows users to access a wide range of diagnostic functions, from reading error codes to viewing live data, all in a hassle-free manner. 

The scan tools’ configuration is streamlined to provide efficient and accurate results, making it a valuable companion for anyone looking to troubleshoot and maintain their vehicles.

Who Should Buy Them?

I would recommend both of these scanners to home mechanics. If you have a preference for physical keypads alongside the touchscreen interface, the Launch CRP123X is a suitable choice. 

However, if you seek a fully touchscreen-operated device, the Launch CRP123E is tailored to meet your requirements.
