Introduction to the Car Scanner App

Car Scanner is a powerful diagnostic app that lets you monitor your vehicle's performance and read diagnostic data in real time. When paired with a WiCAN or WiCAN PRO OBD adapter, it gives you access to your vehicle's onboard diagnostic system over a Wi-Fi connection.

WiCAN vs. WiCAN PRO: This guide covers both WiCAN and WiCAN PRO. The main differences are the default IP address, the port, and how the ECU protocol is selected:

Connecting the WiCAN OBD Adapter

1. Plug in the WiCAN Device

• Insert the WiCAN adapter into your vehicle's OBD-II port.

2. Connect to WiCAN

There are two ways to connect:

• Access Point mode: Connect your phone directly to the Wi-Fi hotspot broadcast by WiCAN.
• Station mode: Connect the WiCAN device to your local Wi-Fi network. In this mode, WiCAN is assigned an IP address by your router.

3. Configure the WiCAN Device

• Open the WiCAN Device Configuration Page by entering the device's IP address in a web browser:
  • Access Point mode: use the default IP: 192.168.80.1 for WiCAN, or 192.168.0.10 for WiCAN PRO.
  • Station mode: use the local IP address assigned to the device by your router.
• Set the protocol to ELM327.
• Recommended: Disable MQTT and BLE to improve performance.
• Submit the changes. The device will reboot after the configuration is saved.

Setting Up the Car Scanner App

4. Configure the Adapter in Car Scanner

1. Open the Car Scanner app and go to:
   Settings -> Adapter OBDII ELM327 -> WiFi.
2. Enter the adapter's IP address and port:
   • Access Point mode: use the default IP: 192.168.80.1 for WiCAN, or 192.168.0.10 for WiCAN PRO.
   • Station mode: use the local IP address assigned to the device by your router.
   • Port: 3333 for WiCAN, or 35000 for WiCAN PRO.
   • Alternatively, use the mDNS address shown in the WiCAN Status tab:
     wican_xxxxxxxxxxxxxxxx.local.

5. Set the ECU Protocol

1. Scroll down in the Car Scanner settings and select:
   Advanced Settings -> ECU Protocol.
2. WiCAN PRO: Select Auto Protocol Detection. No manual protocol selection is required.
3. WiCAN: Choose the protocol that matches your vehicle. WiCAN does not support Auto Protocol Detection, so the protocol must be selected manually. Start with one of these common protocols:
   • 6) ISO 15765-4 CAN (11 bit ID, 500 Kbaud)
   • 7) ISO 15765-4 CAN (29 bit ID, 500 Kbaud)
   • 8) ISO 15765-4 CAN (11 bit ID, 250 Kbaud)
   • 9) ISO 15765-4 CAN (29 bit ID, 250 Kbaud)
   
   If none of these work, try the other protocols in the list until the connection succeeds.

6. Select the Vehicle Profile

1. In the Car Scanner settings, go to Connection Profile (or Car Profile, depending on the app version).
2. Select the profile that matches your vehicle's make and model. Choosing the correct profile enables manufacturer-specific sensors and diagnostics. If your vehicle is not listed, use the generic OBD-II profile.

Connecting to the Vehicle

7. Establish a Connection

• Return to the Car Scanner main page and press Connect.

8. Verify the Connection

If the connection is successful, the app will show:

• ELM Connection: Connected
• ECU Connection: Connected

9. View Supported Sensors

• Press All Sensors to see the data available from your vehicle.

Notes and Tips

• WiCAN: Always select the correct protocol manually, as WiCAN does not support Auto Protocol Detection.
• WiCAN PRO: Use Auto Protocol Detection. Remember that the default IP is 192.168.0.10 and the port is 35000.
• Make sure the correct vehicle profile is selected in Car Scanner; the wrong profile can result in missing sensors or a failed ECU connection.
• In Station mode, the device's IP address may change if your router assigns a new one. Check the WiCAN Status tab or use the mDNS address if the connection stops working.
• For the best performance, disable unused features such as MQTT and BLE.
