Look Under the Driver’s Side Dashboard

Once you find the port, plug the scanner into it firmly. Make sure the connection is secure but don’t force it.

Turn the Vehicle to Accessory Mode

• Accessory mode usually means turning the key one click before the engine starts.

Step 3: Enable WiFi on Your Smartphone or Tablet

Most OBD2 scanner WiFi adapters create a WiFi network you will connect to. Follow these steps:

Open WiFi Settings

Connect to the Scanner’s WiFi

• Select the scanner’s WiFi network.
• Enter the password if required (check your scanner’s manual).

Step 4: Download and Open the OBD2 App

Your OBD2 scanner will work with various apps designed for vehicle diagnostics. Some popular options include Torque, OBDLink, and Car Scanner. Here’s what to do:

Choose an App Compatible with Your Scanner

• Check the scanner’s instructions for recommended apps.
• Download the app from Google Play or Apple App Store.

Open the App and Configure the Connection

• Launch the app and go to its settings.
• Select WiFi as the connection type.
• Choose or enter the IP address and port number if required (usually found in the scanner’s manual).

Step 5: Start Vehicle Diagnostics

With the scanner connected and app ready, you can now start your diagnostics:

Run a Scan

• In the app, select “Scan” or “Read Codes.”
• The app will communicate with your vehicle’s computer and retrieve fault codes.
