The right tool starts
with your vehicle.
Engine diagnostics, deeper system access, or a quick battery check? Match the job before comparing the tools.

- 02 Choose the systems you need to diagnose.
- 03 Pick a screen or a compatible phone app.
Before you plug in
Before you buy.
Will an OBD scanner work with my car?
Compatibility depends on the vehicle’s diagnostic protocol, model year and the tool. A 16-pin connector alone does not guarantee support. Review the individual product details and your vehicle manual.
Does clearing a code fix the problem?
No. Clearing a fault code does not repair the underlying issue. Save the diagnostic information first and investigate the cause before clearing codes.
Screen scanner or Bluetooth adapter?
A screen scanner displays information on the tool. Bluetooth adapters work with compatible apps and phones; app support and available functions vary by model.
What are the shipping options?
Standard shipping is $4.99 and express shipping is $9.99. See our shipping page for supported destinations and delivery information.
