Auto diagnostic testers are tools that help you check issues in your vehicle, so they're repaired properly. When an indicator comes on, such as an ABS or a check engine light, a user can plug these devices into the on-board diagnostic (OBD) connector found under the dash. There are various types of testers that can read specific vehicle makes and models to provide a more accurate diagnosis. Although these tools can clear a dash light, the dash indicator will continue to light up until the root issue is resolved. Certain models help you adjust engine timing, test circuits, check your battery or address other problems under the hood. No matter which model you choose, make sure to follow the instructions to check trouble codes and properly diagnose issues.
