OBD2 Diagnostic Meter Unit KDIAG — vehicle fault reader and live data scanner

Handheld OBD2 Diagnostic Meter Unit KDIAG is a compact vehicle fault reader and live data scanner designed for use with OBD2-compliant cars. The device reads diagnostic trouble codes (DTCs), displays real-time sensor values and supports basic troubleshooting and verification of repairs. Its portable design and straightforward interface make it suitable for quick on-vehicle checks by mechanics and car owners who need immediate information about engine, emissions and sensor status.

Advantages

The Unit KDIAG provides clear retrieval of fault codes and live data without requiring specialized software or a laptop. It presents real-time sensor readings to help identify intermittent issues and verify repairs. The device’s handheld form factor and simple controls reduce setup time and are practical for roadside checks or workshop use. Designed to work with standard OBD2 protocols, it covers a wide range of vehicles that comply with the OBD2 specification.

Suitable for

• Reading and clearing engine fault codes (DTCs)
• Viewing live sensor data such as RPM, coolant temperature and vehicle speed
• Verifying repairs and maintenance after component replacement
• Quick diagnostics during inspections or pre-purchase checks
• Basic troubleshooting by mechanics, technicians and car owners

Key specifications

• Compatibility: OBD2-compliant petrol and diesel vehicles
• Functions: Read and clear diagnostic trouble codes, live data display
• Display: Built-in screen for code and live-data presentation
• Form factor: Handheld, portable unit with physical controls
• Data types: Real-time sensor values (engine RPM, coolant temperature, vehicle speed, etc.)

How to use

Locate the vehicle’s OBD2 port, typically under the dashboard on the driver’s side, and connect the Unit KDIAG to the port. Turn the vehicle ignition to the accessory or run position as required and power on the device. Navigate the device menu to scan for stored and pending fault codes; view live data streams to monitor sensor outputs while the engine is running. Clear codes only after confirming the underlying issue has been addressed. Follow on-screen prompts for code descriptions and basic guidance.

Usage recommendations

Use the Unit KDIAG primarily as a first-level diagnostic tool: confirm codes, observe live sensor values and perform simple code clearing. For complex faults or safety-related repairs, consult vehicle-specific service manuals or professional diagnostic equipment. Keep the vehicle in a well-ventilated area when running the engine during live-data checks.
