Before writing this comparison, our tester Eric Fugere spent tens of hours testing the Launch CRP123E and CRP123X on 7 different cars and 3 light trucks.
The aim of this comparison is to show you the key differences and similarities of the scan tools so that you can find out which is suitable for you.
We will also tell you who should buy them.
Let’s dive in!

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.
| Systems | Live Data Retrieved |
| Engine System | Intake air temperature Fuel trim data Throttle position Misfire cylinder counts Coolant temperature Misfire data Oxygen sensor data Airflow Engine RPM O2 sensor voltage MAF sensor data Ignition timing Air intake humidity Intake manifold pressure Oil pressure |
| ABS system | ABS System Self-Test Results Brake Fluid Pressure ABS Pump Motor Wheel Speed Sensors ABS System Voltage ABS Module Data Wheel Speed Discrepancy ABS Solenoid Activation Lateral Acceleration Steering Angle Sensors |
| Airbag System | Airbag Deployment Status Seatbelt Sensors Reset SRS Code System Self-Test Results Crash Sensors Voltage and Power Supply Seat Occupancy Sensor Occupant Detection Airbag Sensor Airbag Weight Sensor |
| Transmission System | Shift Solenoid Status Transmission Fluid Temperature Transmission input speed sensor Gear Position Torque Converter Clutch Status Tachometer drive shaft Transmission Fluid Pressure |
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.
