Step-by-Step Guide to Using the Wow Car Diagnostic Machine
Once you are acquainted with your device, you can proceed with diagnosing your vehicle. Follow these steps for a basic diagnostic scan:
Connecting to Your Vehicle’s OBD2 Port
The OBD2 port is usually located under the dashboard on the driver’s side of most vehicles.
- Locate the OBD2 Port: Look for a 16-pin port, typically trapezoidal in shape, beneath the steering column or in the vicinity of the pedals.
- Turn Off the Ignition: Ensure your vehicle’s ignition is turned off before connecting the diagnostic tool.
- Connect the OBD2 Cable: Firmly plug one end of the OBD2 cable into the Wow Car Diagnostic Machine and the other end into your vehicle’s OBD2 port. Ensure a secure connection.
Navigating the User Interface
With the device connected, you’ll need to navigate the user interface to initiate a scan.
- Turn on the Ignition (Accessory Mode): Turn your vehicle’s key to the “accessory” position. This provides power to the car’s systems without starting the engine.
- Power on the Diagnostic Tool: Turn on your Wow Car Diagnostic Machine. It should power up and may automatically detect the connection to your vehicle.
- Select Vehicle Information: You may need to manually enter your vehicle’s information (VIN, make, model, year) or the tool might automatically detect it. Follow the prompts on the screen.
- Navigate the Menu: Use the navigation buttons to find the “Diagnostic Scan” or similarly labeled option in the main menu.

Running a Diagnostic Scan
Initiating the scan allows the Wow machine to communicate with your vehicle’s computer and check for issues.
- Start the Scan: Select the “Diagnostic Scan” option and confirm your choice to begin scanning.
- Wait for the Scan to Complete: The diagnostic tool will communicate with various vehicle systems. This process may take a few minutes. Do not disconnect the tool or turn off the ignition during the scan.
- Review the Scan Results: Once the scan is complete, the Wow Car Diagnostic Machine will display any Diagnostic Trouble Codes (DTCs) found, along with descriptions.
Reading and Interpreting Diagnostic Trouble Codes (DTCs)
DTCs are codes used by the vehicle’s onboard diagnostic system to alert you to potential problems.
- Access DTCs: Navigate to the section in the diagnostic tool that displays DTCs.
- Record the Codes: Write down or take a picture of any DTCs displayed. These codes are crucial for further diagnosis.
- Interpret the Codes: Use the Wow Car Diagnostic Machine’s built-in DTC lookup function (if available) or consult online resources or your vehicle’s repair manual to understand what each code means. DTCs are typically alphanumeric and indicate the system and specific component that is experiencing an issue. For example, a code starting with “P” usually relates to powertrain issues.

Clearing Error Codes (with Caution)
After addressing the issues indicated by the DTCs, you can use the Wow Car Diagnostic Machine to clear these codes.
- Navigate to the Clear Codes Function: Find the “Clear Codes” or “Erase DTCs” option in the menu.
- Clear the Codes: Follow the prompts to clear the codes. Caution: Only clear codes after you have properly diagnosed and repaired the underlying issue. Clearing codes without fixing the problem will only temporarily turn off the check engine light, and the issue will likely return.
- Verify the Repair: After clearing codes and performing repairs, rescan the vehicle to ensure no new DTCs appear and the original issues have been resolved.
