Handheld OBD2 Diagnostic Scanner with Live Data
DETAILS
Understand what is behind your check-engine light with our handheld OBD2 diagnostic scanner. Read fault codes, view their definitions and check live engine data directly on the built-in color screen. The standalone wired design puts essential engine and emissions diagnostics in your hands, without a phone, app or Bluetooth pairing.
- Read and clear check-engine codes: Retrieve OBD-II trouble codes to guide your troubleshooting, then clear erasable codes after the underlying issue has been addressed.
- Live data and visual graphs: Follow supported engine readings as they change, with graphical views that help make trends easier to spot.
- Freeze-frame fault information: View the operating conditions recorded when an emissions-related fault occurred, adding useful context beyond the code number.
- One-touch emissions readiness: Use the dedicated I/M button to check which emissions monitors have completed their self-tests before inspection or smog testing.
- Clear 2.8-inch color display: Read diagnostic information and navigate menus using straightforward physical controls.
- Built-in troubleshooting guidance: DTC Lookup and HELP functions provide code definitions and diagnostic reference information while you work.
- Save, review and print: Revisit recorded codes, data streams and freeze-frame information. Print saved code and data-stream reports through a compatible Windows PC using LAUNCH software.
- Additional OBD-II checks: Access supported oxygen-sensor and on-board monitor test results, request an EVAP system test and retrieve vehicle identification information.
Good For: Mechanics, home garages and hands-on vehicle owners carrying out check-engine troubleshooting, post-repair checks and routine OBD-II diagnostics.
Compatibility: For standard OBD-II/EOBD engine and emissions diagnostics on compatible vehicles. Available functions vary by vehicle. This is not a full-system ABS, airbag or service-reset scanner.
Please Note: Clearing codes does not repair a fault, can reset emissions readiness and does not erase permanent trouble codes.

Footwear Size Guide
For the best fit, measure your foot length (cm) and use the chart below. If you're between sizes, we recommend sizing up.
How to Measure Your Foot
- Use a sheet of paper: Place it against a wall on a hard floor.
- Stand and mark: Heel lightly against the wall, mark your longest toe.
- Measure heel to toe: Measure the distance in cm.
- Measure both feet: Use the longer measurement.
- Wear your usual socks: If you’ll wear sports socks, measure with them on.
