Experiencing car trouble can be stressful, and when that check engine light illuminates, your first thought might be to find out what’s wrong—quickly and affordably. Free diagnostic scans are often advertised, but understanding what they offer and where to access them is crucial. This article will guide you through where you can get a free diagnostic scan for your car and what to expect from this service.
Understanding the Free Diagnostic Scan
A free diagnostic scan typically involves using an OBD-II (On-Board Diagnostics II) scanner to read trouble codes from your vehicle’s computer system. These codes are generated when your car’s sensors detect an issue, and they can provide a starting point for understanding potential problems. Many auto parts stores offer this service as a customer draw, aiming to sell you the parts needed for the repair.
Auto Parts Stores: A Common Option for Free Scans
One of the most readily available places for a free diagnostic scan is your local auto parts store. Major chains like AutoZone, Advance Auto Parts, and O’Reilly Auto Parts often provide this service. Typically, a store employee will use a handheld OBD-II scanner to retrieve the error codes from your car.
