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. Use the scanner compatibility checklist.
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. Read about readiness monitors and 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. Compare screen scanners and Bluetooth adapters.
What are the shipping options?
Standard shipping is $4.99 and express shipping is $9.99. See supported destinations and shipping details.
