LAUNCH CRP123X Plus OBD2 Scanner Professional All System Car Diagnostic Tool

The LAUNCH CRP123X Plus OBD2 Scanner is a powerful and upgraded automotive diagnostic tool designed for DIY users, mechanics, workshops, and professional technicians who require fast, accurate, and comprehensive vehicle diagnostics. As the upgraded version of the CRP123X, the 2026 LAUNCH CRP123X PLUS combines advanced hardware, intelligent software, and all-system vehicle diagnostics into one compact and user-friendly scan tool.

This professional OBD2 diagnostic scanner performs full-system diagnostics for major vehicle systems including Engine, Transmission, ABS, SRS (Airbag), Brake System, TPMS, Steering Angle Sensor (SAS), and more. With a single tap, the scanner quickly reads all available ECU modules, retrieves diagnostic trouble codes (DTCs), clears fault codes, and displays live data streams in real time. The system automatically generates diagnostic reports that can be stored, replayed, shared, or printed for vehicle maintenance tracking and repair documentation.

Real-Time Battery Monitoring & Intelligent Vehicle Health Reports

The LAUNCH CRP123X PLUS OBD2 code reader includes an advanced real-time battery voltage monitoring function that displays battery voltage data in graphical waveform format. Instead of viewing confusing numerical readings, users can easily understand the battery’s condition through visual graphs, helping identify charging issues or battery health problems quickly and accurately.

After every diagnostic session, the scanner automatically creates a detailed vehicle health report containing:

• Vehicle VIN information
• Vehicle make and model
• Vehicle year
• Device information
• Diagnostic scan results
• Fault code information

Reports can be easily exported as PDF files through WiFi and shared via email with customers, technicians, or workshop staff. Users can also print reports by connecting the scanner to a PC, making this feature especially valuable for repair shops and professional garages.

4-in-1 Live Data Stream & Enhanced Diagnostics

The CRP123X Plus scan tool supports 4-in-1 live data graphing, allowing users to compare multiple data streams simultaneously for faster and more accurate troubleshooting. This feature simplifies complex diagnostics and helps users identify abnormal sensor readings, engine behavior, and system faults more efficiently.

The built-in “MALL” module allows users to expand scanner capabilities by purchasing additional software and diagnostic functions directly within the device. This enables workshops and technicians to upgrade diagnostic coverage without purchasing additional hardware.
