For car owners and professional mechanics alike, having a reliable OBD2 scanner is indispensable. The Launch CRP123 Professional emerges as a compelling option, promising extensive diagnostic capabilities in a user-friendly, handheld device. Priced affordably, this scanner aims to bridge the gap between basic code readers and high-end professional tools. Let’s delve into a comprehensive Launch CRP123 Professional review to see if it lives up to the hype and whether it’s the right diagnostic companion for your automotive needs.
Key Features and Specifications of the Launch CRP123 Professional
Before we explore its performance, let’s outline the specifications that define the Launch CRP123 Professional:
- Dimensions: 7.8 x 4.2 x 1.1 inches
- Weight: 10.3 ounces
- Live Data Stream: Yes
- Display: 3.5-inch Color Screen
- Buttons: 7 Physical Buttons
- Bluetooth & App Connectivity: No
- Form Factor: Handheld
- Warranty: 1 Year
These specifications highlight a compact and lightweight device designed for handheld use, featuring a color display for data visualization and essential functionalities for comprehensive vehicle diagnostics.
Design and Handling: Compact and User-Friendly
The Launch CRP123 Professional boasts a horizontally oriented design, making it comfortable to hold and operate. Its dimensions are slightly more compact than competitors like the Foxwell NT614, and the inclusion of finger cutouts at the back enhances grip security. Weighing just 10.3 ounces, it’s significantly lighter than the NT614, reducing hand fatigue during prolonged use.
While it necessitates two-handed operation, the button layout and menu navigation are intuitive. The 3.5-inch screen, although smaller than some competitors, provides clear and readable display of diagnostic information. Unlike some newer scanners, it forgoes a touchscreen interface, relying on physical buttons for navigation – a design choice that some users may find more reliable in a workshop environment.
The front of the device features LED indicators for power and OBD connection status. Internally, the CRP123 Professional is equipped with a comprehensive database of generic OBD2 codes and manufacturer-specific codes, expanding its diagnostic reach across various car brands and models. However, it’s worth noting that it doesn’t offer repair suggestions or parts recommendations, features found in some Innova scanners.
Connectivity-wise, the top of the scanner houses the OBD cable connector, while the bottom includes a micro USB port for firmware updates and data transfer. A micro SD card slot, protected by a hinged door, accommodates the included 16GB card for data logging and transfer.
Setup and Ease of Use: Ready to Diagnose
Setting up the Launch CRP123 Professional is remarkably straightforward. Upon plugging it into the OBD-II port of a vehicle, the scanner powers on within seconds, presenting a clear menu interface with options for “Diagnose,” “Settings,” and “Help.” The menu is intuitive, allowing users to quickly access the scanner’s functionalities.
The included OBD cable, however, is a bit short at 46 inches, limiting its usability outside the car cabin. For engine bay diagnostics, an OBD extension cable might be necessary. 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 1-year warranty and lifetime firmware updates, demonstrating commitment to product support. Their website offers basic support for updates and formatting, with email and phone support available for further assistance, though phone calls may incur charges.
Performance and Diagnostic Capabilities: Deep Dive into Vehicle Health
The Launch CRP123 Professional stands out for its extensive diagnostic capabilities, catering to both DIY enthusiasts and professional mechanics. Beyond basic OBD2 functions like reading and clearing codes, it performs in-depth diagnostics across various vehicle systems. It excels in pre-inspection I/M Readiness tests and accurately retrieves the Vehicle Identification Number (VIN).
This scanner can execute comprehensive diagnostic tests on critical systems, including:
- Catalytic Converter
- Oxygen Sensors
- ABS (Anti-lock Braking System)
- Airbags
Furthermore, it offers practical reset functions such as oil light reset and steering angle adjustment, adding to its versatility in automotive maintenance. In performance testing, the CRP123 Professional demonstrated rapid response in identifying and displaying fault codes. It successfully diagnosed an induced fault by quickly registering a disconnected oil temperature sensor and allowed for easy clearing of the Check Engine Light after issue rectification.
Data display is flexible, offering both numerical and graphical representations of live data streams. The inclusion of a 16GB microSD card and USB connectivity facilitates data logging and printing of diagnostic reports via a computer. While it lacks battery power and relies on vehicle power, the included microSD card compensates by enabling data portability, a feature absent in some competitors like the Topdon ArtiDiag 500.
