OBD2 diagnostic scanner Ancel BM700 — supports all OBD2 protocols

The Ancel BM700 is an OBD2 diagnostic scanner that supports all OBD2 protocols and is designed to read and clear diagnostic trouble codes, display live sensor data and basic vehicle information, and help identify engine- and emission-related faults. It is suitable for both DIY users and professional mechanics who need a compact handheld device for troubleshooting and routine maintenance on OBD2-equipped cars.

Advantages

The BM700 provides broad OBD2 compatibility across vehicle makes while also including extended diagnostic and service functions tailored for BMW, MINI and Rolls-Royce models. It combines live data monitoring, I/M readiness checks and EVAP testing with the ability to reset service indicators, perform adaptations and register batteries. The device is powered directly from the vehicle OBD socket and features a backlit graphic display and function buttons for straightforward operation.

Suitable for

• Reading and clearing engine fault codes on OBD2-equipped cars
• Monitoring live sensor data and checking I/M readiness
• Basic emission-related diagnostics including EVAP testing
• Owners and mechanics working on BMW, MINI and Rolls-Royce who need extended system access
• Garages and DIY users needing a handheld universal OBD2 scanner

When it may not be suitable

The BM700 provides extensive OBD2 engine diagnostics and BMW-specific service functions, but it is not a lab-grade diagnostic station. Advanced programming, deep ECU coding beyond injector coding and manufacturer-level dealer programming procedures may require factory-level tools or software. For certain complex vehicle systems or brand-specific features not covered by OBD2 protocols, a full dealer diagnostic tool may be necessary.

Key specifications

• Device type: Handheld OBD2 diagnostic scanner with extended support for BMW systems
• Protocol support: All standard OBD2 protocols
• Functions: Read/clear trouble codes, live data, I/M readiness, EVAP test, vehicle information (VIN, calibrations)
• BMW-specific functions: Diagnostics for engine, transmission, ABS, SRS and ESP; service resets and adaptations; battery registration; SAS calibration; DPF regeneration and injector coding
• Display: Backlit graphic display
• Controls: Dedicated function buttons
• Power supply: 12 V via OBD socket
• Software updates: Free lifetime updates

How to use

Connect the BM700 to the vehicle OBD2 socket; the device is powered by the vehicle's 12 V supply. Navigate the menu using the function buttons to select vehicle make or OBD2 mode, then choose the desired operation such as reading codes, viewing live data or performing service functions. Follow on-screen prompts to read and clear fault codes, view VIN and vehicle information, run I/M readiness or EVAP tests, and perform available BMW service resets and adaptations. Use the backlit graphic display to review live sensor values and diagnostic messages.

What to consider before purchase

• Ensure the target vehicle is OBD2-equipped and that the required functions are supported via OBD2 for that make and model
• For full BMW system access, verify that the listed BMW-specific service functions meet your needs for adaptations, resets and battery registration
• Dealer-level programming or deep ECU coding may not be supported and could require manufacturer-specific tools
• Confirm compatibility with older BMW series if you intend to use the device on legacy models

Usage recommendations

Use the BM700 as a first-line diagnostic and service tool: start with a code read and live data check to identify issues, then perform service resets and adaptations as required. Keep the device firmware updated to retain protocol coverage and the latest function sets.
