You don't need to be a professional mechanic to take full advantage of using a car scanner. With the right tools and a bit of know-how, anyone can conduct thorough inspections and understand the diagnostics of their vehicle. In this guide, we'll show you exactly how to fully utilize your car scanner to keep your vehicle running smoothly and efficiently. Whether you're looking to resolve dashboard warning lights or simply want to optimize your car's performance, Learning how to use your car scanner that can save you time and money.
How Do You Scan A Car With A Scanner
Scanning a car with a scanner typically involves using a specialized device that is engineered to interact with and diagnose issues within a vehicle's complex electronic systems. These devices, known as OBD-II scanners, are essential tools in modern automotive troubleshooting. They provide critical insights into the status of various systems and components by reading the codes generated by the car’s onboard computer. Here’s a general guide on how to do it:
- Locate the Diagnostic Link Connector (DLC): Most cars have the DLC under the dashboard on the driver's side. It's a 16-pin connector where the scan tool plugs in. The location can vary, so check your vehicle's owner manual if it’s not immediately visible.
- Plug in the Scanner: With the car’s ignition off, connect the scanner to the DLC. Make sure it’s securely connected.
- Turn on the Ignition: Switch the car's ignition to "On" or "Run" (not starting the engine). This powers the car's electronics and the scanner.
- Initialize the Scanner: Follow the scanner’s instructions to initialize it. This may involve selecting the make and model of your car or allowing the scanner to auto-detect the vehicle.
- Perform a Scan: Navigate the scanner’s menu to select the type of scan you want to perform. You can do a general scan of all systems or target specific parts like the engine, transmission, ABS, etc. Start the scan and wait for the scanner to retrieve the data.
- Read the Codes: Once the scan is complete, the scanner will display any diagnostic trouble codes (DTCs) it has found. These codes are typically alphanumeric and can indicate what might be wrong with the vehicle.
- Interpret the Codes: Use the scanner's manual, an online database, or a professional service to interpret what the codes mean. This will tell you what issues have been detected and can guide repairs.
- Clear Codes: If applicable, you can use the scanner to clear the trouble codes. This is useful after fixing the issues detected. However, simply clearing the codes without repairs won’t solve underlying problems and the codes will likely reappear.
- Disconnect the Scanner: Turn off the ignition, remove the scanner, and store it safely.

Do You Turn Car On When Using OBD2 Scanner
Should the car be running? The answer isn't straightforward and depends on what you need to check. Here’s how to determine when to keep your engine running and when it’s safe to turn it off.
Engine Off: Preliminary Checks
For initial diagnostics, such as reading error codes, you do not necessarily need to have your engine running. In this phase, simply turning your vehicle’s ignition to the 'on' position activates the electrical system, allowing your scanner to communicate with the car’s computer. This is sufficient for retrieving stored data.
Engine On: Real-Time Data Monitoring
If your diagnostic checks require monitoring real-time data or if you need to clear certain codes, having your engine running might be necessary. This includes tasks like checking the engine’s RPM, live fuel injection data, or emission system status. For accurate readings, keep the engine idling.
Regardless of whether your engine is on or off, always ensure you’re parked in a safe location and that the car is in neutral or park. Safety should never be compromised during diagnostic procedures.
Do Car Scanners Work On All Cars
Car scanners come in a variety of forms, ranging from basic code readers to professional-grade scan tools that offer extensive diagnostics. Basic models provide error codes from the engine control unit (ECU), while more advanced scanners can monitor a wider range of systems and provide detailed feedback.
Since 1996, the On-Board Diagnostics II (OBD-II) standard has been mandatory for all cars sold in the United States. This standard ensures that most scanners can interface with these vehicles. If your car is a 1996 model or newer, an OBD-II scanner is likely to work with your vehicle.
Older vehicles, especially those manufactured before 1996, might not support OBD-II scanners. These cars often require specific adapters or proprietary scanners designed for their unique systems. Similarly, high-end luxury cars or specialized vehicles might use unique diagnostic systems, limiting the compatibility of universal scanners.
For deeper diagnostics, enhanced scanners are capable of interfacing with car systems beyond the standard ECU. These tools can read transmission codes, ABS (Anti-lock Braking System) codes, and other specialized data. However, their effectiveness can vary based on the car's make and model.
Before purchasing a scanner, check its compatibility with your car’s model and year, especially if you own an older or more specialized vehicle.
While no single car scanner works universally on all vehicles, a wide range of tools are available to suit nearly every need.
