The Launch CRP123X OBD2 scanner stands out as a robust diagnostic tool designed for both car enthusiasts and professional mechanics. If you’re seeking an OBD scanner that delivers substantial diagnostic capabilities combined with a user-friendly interface, the Launch CRP123X deserves a closer look. This review will delve into the features, design, performance, and overall value of this popular scan tool.
First Impressions: Design and Build
The Launch CRP123X boasts a horizontally oriented design, prioritizing functionality within a compact form factor. Measuring approximately 7.4 x 4.3 x 1.1 inches and weighing in at a mere 10.3 ounces, it’s noticeably more portable than comparable scanners like the Foxwell NT614. The inclusion of finger cutouts on the back panel enhances grip and handling, crucial for comfortable use in various garage environments.
While operation necessitates two hands, the lightweight nature of the CRP123X is a welcome departure from heavier alternatives, reducing fatigue during extended diagnostic sessions. The 3.5-inch color display, while functional, might feel somewhat small to users accustomed to larger screens, especially when considering competitors offering 4.3-inch displays. Similar to the NT614, the CRP123X forgoes a touchscreen interface, relying on physical buttons for menu navigation.

Navigating the scanner is facilitated by seven physical buttons, including a directional keypad for menu traversal and code actuation, an escape button, and a dedicated button for accessing diagnostic code definitions from the integrated database. While lacking shortcut keys found on some competing models, the button layout is intuitive and responsive. Front-facing LEDs clearly indicate power status and connection to the vehicle’s diagnostic system. Internally, the CRP123X is equipped with both generic OBD-II codes and manufacturer-specific codes, expanding its diagnostic scope. However, it’s worth noting that unlike some Innova scanners, the CRP123X does not offer repair suggestions or parts recommendations.
The top of the device houses the OBD cable connector, while the bottom features a micro USB port for firmware updates and connectivity to printers. A covered micro SD card slot accommodates the included 16GB card for data storage and transfer.

Setting Up and Getting Started
The Launch CRP123X offers a straightforward setup process. Upon connecting the scanner to the OBD-II port of a vehicle, the device powers on rapidly and presents a clear menu interface with options for “Diagnose,” “Settings,” and “Help.” The included 46-inch OBD cable, while standard, may be restrictive for engine bay diagnostics, often requiring an extension cable for comfortable reach. However, the scanner functioned seamlessly with a standard OBD extension cable during testing.
The package includes essential accessories such as a USB cable, OBD cable, 16GB microSD card, microSD card reader, and a quick start guide. Launch provides a standard 1-year warranty and lifetime firmware updates, ensuring long-term usability and value. While their website offers resources for printing and formatting the SD card, direct technical support is primarily available via email or paid phone calls.
Performance and Diagnostic Capabilities
The Launch CRP123X positions itself as a versatile tool suitable for both DIY enthusiasts and professional mechanics, exceeding basic OBD scanner functionalities. Beyond standard features like pre-inspection I/M Readiness testing and VIN retrieval, the CRP123X demonstrates comprehensive diagnostic prowess. It effectively executes complete diagnostic scans across major vehicle systems, including the catalytic converter, oxygen sensors, ABS, and airbag systems. Furthermore, it offers practical reset functions such as oil light reset and steering angle adjustment.
In performance testing, the CRP123X exhibited rapid response to induced faults, such as disconnecting the oil temperature sensor. Crucially, it successfully cleared the Check Engine Light after the issue was resolved.

Diagnostic data can be displayed numerically or graphically on the scanner screen. The included USB cable enables connection to a computer for data printing and analysis. Unlike some battery-powered scanners, the CRP123X relies on vehicle power, but the included 16GB microSD card facilitates data transfer and logging.
Final Verdict: Is the Launch CRP123X Worth It?
The Launch CRP123X OBD2 scanner strikes a compelling balance between price and performance, making it a strong contender for both home mechanics and professional technicians. While its OBD cable length could be improved for engine bay work, and it lacks touchscreen functionality, the CRP123X delivers a robust suite of diagnostic tests and essential reset capabilities for its price point. Its ease of use, extensive vehicle system coverage, and data logging features solidify its position as a valuable OBD2 scan tool. For those seeking a feature-rich OBD2 scanner without breaking the bank, the Launch CRP123X represents excellent value and diagnostic capability.
