Understanding OBD2 and Why You Need a Scanner
Before we dive into the specifics of Audew scanners, let’s clarify what OBD2 is and why it’s a game-changer for car owners. OBD2, or On-Board Diagnostics II, is a standardized system implemented in most cars manufactured after 1996. This system monitors various aspects of your vehicle’s engine and emissions systems, storing valuable data about its performance and any potential malfunctions.
Think of your car’s OBD2 system as its internal health monitor. When something goes wrong, like a misfiring engine or a faulty sensor, the system logs Diagnostic Trouble Codes (DTCs) and often illuminates the check engine light. This is where an OBD2 scanner becomes indispensable.
An OBD2 scanner is a handheld device that plugs into your car’s OBD2 port, typically located under the dashboard on the driver’s side. Once connected, it communicates with your car’s computer and retrieves the stored DTCs and other vital information. This allows you to:
- Identify the cause of the check engine light: No more guessing games! An OBD2 scanner translates cryptic error codes into understandable descriptions, pinpointing the source of the problem.
- Save money on diagnostics: Mechanics often charge for diagnostic services. With your own scanner, you can perform initial diagnoses yourself, saving time and money.
- Make informed repair decisions: Understanding the problem empowers you to decide whether you can tackle the repair yourself or if professional help is needed.
- Monitor your car’s health: Beyond error codes, many scanners provide real-time data on engine temperature, speed, and other parameters, allowing you to proactively monitor your car’s performance.
Audew Car Scanner OBD2: Features and Benefits
Audew has emerged as a reputable brand in the automotive diagnostic tool market, offering a range of OBD2 scanners designed to meet the needs of various users, from beginners to experienced mechanics. Audew car scanners are known for their user-friendliness, comprehensive features, and affordability. Let’s explore some key features and benefits you can expect from an Audew OBD2 scanner:
Key Features:
- Wide Vehicle Compatibility: Audew scanners are generally compatible with most OBD2 compliant vehicles manufactured after 1996, covering a broad range of makes and models.
- Read and Erase Diagnostic Trouble Codes (DTCs): The core function of any OBD2 scanner, Audew scanners allow you to read both generic and manufacturer-specific DTCs, providing detailed descriptions of the issues. Crucially, they also enable you to erase codes and turn off the check engine light after repairs are made.
- Live Data Stream: Monitor real-time sensor data, including engine RPM, coolant temperature, vehicle speed, oxygen sensor readings, and more. This live data stream is invaluable for diagnosing intermittent issues and understanding how your engine is performing under various conditions.
- Freeze Frame Data: When a DTC is triggered, the scanner captures a “snapshot” of sensor data at that precise moment. This “freeze frame” information provides crucial context for diagnosing the problem, showing the conditions under which the fault occurred.
- O2 Sensor Test: Oxygen sensors play a vital role in emissions control and fuel efficiency. Audew scanners often include O2 sensor testing capabilities to ensure these sensors are functioning correctly.
- EVAP System Test: The Evaporative Emission Control System (EVAP) prevents fuel vapors from escaping into the atmosphere. Audew scanners may offer EVAP system tests to identify leaks or malfunctions in this system.
- On-Board Monitor Test: This feature allows you to access the results of on-board diagnostic monitoring tests for specific components and systems.
- Vehicle Information (VIN, CIN, CVN): Retrieve essential vehicle information like Vehicle Identification Number (VIN), Calibration Identification Number (CIN), and Calibration Verification Number (CVN).
- User-Friendly Interface: Audew scanners are designed with ease of use in mind, featuring intuitive menus, clear displays, and straightforward navigation.

How to Use an Audew Car Scanner OBD2: A Step-by-Step Guide
Using an Audew car scanner is generally straightforward. Here’s a basic step-by-step guide:
-
Locate the OBD2 Port: Turn off your car’s ignition. Find the OBD2 port, usually located under the dashboard on the driver’s side. Refer to your car’s owner’s manual if you have trouble locating it.
-
Connect the Scanner: Plug the Audew scanner’s OBD2 connector firmly into the OBD2 port.
-
Turn on Ignition (Key On, Engine Off): Turn your car’s ignition to the “key on, engine off” position. This provides power to the car’s computer without starting the engine.
-
Power On the Scanner: The Audew scanner should power on automatically once connected and the ignition is on. If not, press the power button on the scanner.
-
Navigate the Menu: Use the scanner’s buttons to navigate to the “Diagnostics” or “Read Codes” menu option. The exact menu layout may vary slightly depending on the specific Audew scanner model.
-
Read Diagnostic Trouble Codes (DTCs): Select the option to read DTCs. The scanner will communicate with your car’s computer and display any stored error codes.
-
Record and Research Codes: Carefully note down the DTC codes and their descriptions. You can use online resources or your car’s repair manual to research the meaning of the codes and potential causes.
-
View Live Data (Optional): If you want to monitor live data, navigate to the “Live Data” or “Data Stream” menu option. Select the parameters you want to monitor (e.g., engine temperature, RPM).
-
Erase Codes (After Repair – Optional but Cautious): If you have addressed the issue that caused the DTCs and want to clear the check engine light, navigate to the “Erase Codes” or “Clear DTCs” menu option. Important: Only erase codes after you have properly diagnosed and repaired the underlying problem. Erasing codes without fixing the issue will only temporarily turn off the light, and it will likely return.
-
Disconnect the Scanner: Once you are finished, turn off the ignition and disconnect the Audew scanner from the OBD2 port.
Important Notes:
- Consult Your Scanner’s Manual: Always refer to the user manual that comes with your specific Audew scanner model for detailed instructions and features.
