OBD2 Automotive Scanner Diagnostic Tool for Vehicles Since 1996

What It Is / How It Works

OBD2 automotive scanners are diagnostic tools that connect to a vehicle's OBD2 port and read engine fault information. Scanners in this category display fault codes so the driver or mechanic can see what the engine control system has recorded.

Who It's For / Use Cases

OBD2 automotive scanners suit car owners who want to check why a warning light is on before visiting a shop, and home mechanics who keep an eye on their own vehicles. They suit people who maintain more than one vehicle and want one tool for reading engine fault information across OBD2-protocol cars.

How to Use / Care

1. Use it to diagnose engine faults on vehicles that use the OBD2 protocol.

How to Choose

Start by confirming that the vehicle uses the OBD2 protocol. OBD2 scanners vary in how much fault information they display, so match the scanner to the vehicles you service and the level of detail you need.
