universal obd scanner

A **universal OBD scanner** is a diagnostic tool designed to work with most vehicles that use the standardized On-Board Diagnostics (OBD-II) system. It connects to a vehicle’s OBD port—typically located under the dashboard—and retrieves diagnostic information from the car’s computer.

Unlike manufacturer-specific scanners, a universal OBD scanner can read and clear generic trouble codes across many different makes and models (generally vehicles made from 1996 onward in the U.S. and many countries). Common functions include:

- Reading and clearing check engine light (CEL) codes
- Displaying real-time engine data (live data)
- Viewing freeze frame data
- Checking emissions readiness status

Some advanced universal scanners may also support enhanced diagnostics, ABS/SRS codes, and additional vehicle systems, depending on compatibility.

In short, a universal OBD scanner is a multi-brand vehicle diagnostic device that works with most OBD-compliant cars.
