A car scanner diagnostic tool, also known as an OBD2 scanner, is an essential tool for any car owner. It allows you to diagnose car problems yourself, saving you time and money on potentially expensive mechanic visits. AutoZone offers a variety of car scanner diagnostic tools to help you quickly identify and resolve vehicle issues. This guide will walk you through connecting, using, and understanding the results from a car scanner diagnostic tool.
Connecting Your Car Scanner Diagnostic Tool
Locating the OBDII port is the first step. This port, a trapezoid-shaped 16-pin connector, is typically found under the driver’s side dashboard. In some cases, it might be hidden in the center console or under the passenger side dash. Connecting the car scanner diagnostic tool is straightforward. The connector only fits one way, ensuring a proper connection.
Here’s the correct connection procedure:
- Ignition Off: Make sure your car’s ignition is turned off before connecting the scanner.
- Connect the Tool: Plug the car scanner diagnostic tool into the OBDII port.
- Ignition On: Turn the ignition to the “on” position, but don’t start the engine. This powers up the scanner.
- Boot Up: Wait for the car scanner diagnostic tool to complete its startup process.
- Input Information: The tool may prompt you for vehicle information like engine size or VIN.

Navigating the Car Scanner Diagnostic Tool Menu
Once your car scanner diagnostic tool is ready, you’ll see a menu with various options. These options may vary depending on the complexity of your tool, but common selections include:
- Read Codes: This displays Diagnostic Trouble Codes (DTCs) indicating specific faults. Many car scanner diagnostic tools from AutoZone provide descriptions of these codes.
- Erase Codes: This clears the DTCs from the vehicle’s computer memory after repairs are made.
- Live Data: This feature allows you to monitor real-time sensor readings, helping pinpoint issues. Some AutoZone car scanner diagnostic tools offer this functionality.
- Freeze Frame: This captures vehicle data at the moment a DTC was set, offering valuable diagnostic clues.
- Vehicle Info: This displays basic information about your vehicle.
- I/M Readiness: This indicates your vehicle’s readiness for emissions testing.
Deciphering Diagnostic Trouble Codes (DTCs)
DTCs are alphanumeric codes (e.g., P0301) that pinpoint specific problems.
- The first letter (P, B, C, or U) indicates the system affected (Powertrain, Body, Chassis, or Network).
- The first number (0 or 1) indicates whether the code is generic (0) or manufacturer-specific (1).
- The remaining numbers identify the specific fault within the system.
For example, P0301 indicates a generic powertrain code related to a cylinder 1 misfire. Understanding these codes allows for targeted repairs. Resources like AutoZone’s website provide detailed information on DTCs.
