KW340 OBD2 Car Diagnostic Scanner With Engine Battery And Code Reader

The KONNWEI KW340 plugs into your car’s OBD-II port to instantly reveal engine trouble lights and battery status. You will know exactly what causes that dashboard warning without guessing or waiting for a mechanic appointment.

This handheld code reader clears fault codes after you complete a repair, so you can verify the fix directly from the driver seat. The bright 2.8-inch color display stays legible under bright garage lights or deep shade. Tap the dedicated one-click buttons to pull freeze frame snapshots or grab live sensor data in seconds.

Benefits & Tips

Press the I/M readiness key to confirm your vehicle meets local emissions standards before your scheduled inspection booking.

Keep the scanner clipped to your center console between drives. The direct OBD-II connection pulls power straight from your electrical system, meaning it wakes up instantly when cold temperatures trigger weak-start alerts.

Run the built-in battery voltage check monthly during seasonal shifts. Quick readings across the 8V to 18V range point out weakening cells long before they leave you stranded.
