Vehicle Compatibility

This scanner is designed for vehicles fitted with a standard 16-pin OBD2/EOBD diagnostic connector.

It is generally intended for petrol vehicles meeting OBD2 requirements and diesel vehicles meeting EOBD requirements. Compatibility can vary depending on the vehicle’s make, model, year, engine type and diagnostic system.

Please confirm that your vehicle has a standard OBD2/EOBD socket before purchase. The tool is primarily intended for engine-related diagnostics and may not support ABS, airbag, transmission, service reset, body control or other manufacturer-specific systems.

How to Use

1. Locate the vehicle’s 16-pin OBD2 diagnostic socket, usually found beneath the dashboard.
2. Switch off the ignition and connect the scanner.
3. Turn the ignition on without starting the engine, unless otherwise required.
4. Follow the on-screen instructions to scan for fault codes.
5. Record the displayed code before clearing it.
6. Investigate and repair the underlying fault before erasing any code.
7. Carry out a second scan to confirm the result where appropriate.

Important Notes

• A fault code identifies an area or system that may require attention; it does not always identify the exact failed component.
• Clearing a code does not repair the underlying problem.
• Some vehicles may require a professional or manufacturer-specific diagnostic tool.
• Compatibility and available functions may vary between vehicles.
• Always follow the vehicle manufacturer’s safety and diagnostic procedures.
• Do not operate the scanner while driving.
• If the engine warning light remains on after clearing, further diagnosis may be required.
