Have you ever been on a long road trip, only to have your car suddenly sputter to a stop? You check under the hood, but everything seems fine. Frustration sets in, and you’re left wondering what could be wrong. This is where a DIY OBD scan tool comes in handy.
What is a DIY OBD Scan Tool?
An OBD (On-Board Diagnostics) scan tool is a diagnostic device used to communicate with a vehicle’s computer system and retrieve diagnostic trouble codes (DTCs). These codes provide valuable information about potential issues within the vehicle’s engine, transmission, emissions system, and more.
