Device Connection

Physical Connection

Carefully insert the device into the vehicle's OBD-2 diagnostic connector until it is fully seated. The OBD-2 port is typically located under the steering wheel, in the glove compartment, or in the center console, depending on the vehicle's make and model.

Activate the device's power by pressing the button on the front panel. The indicator light on the adapter should illuminate.

Powering On and Initial Connection

Turn on the vehicle's ignition and start the engine after approximately 10 seconds. Wait for about 30 seconds after the engine starts.

Open the "Car Scanner" application on your smartphone. On the main screen, tap the "Connect" button. The device will begin scanning your vehicle. Once initialization is successful, the status will display as "Connected". You can then proceed with diagnostics.

Bluetooth Connection via App

Step 1: Download and Install App

Download and install the "Car Scanner" application from your phone's App Store or Google Play.

Step 2: Open Phone Bluetooth Settings

On your phone, open the Bluetooth settings.

Step 3: Configure App Connection

Within the "Car Scanner" app:

• Tap on the "Settings" menu.

Troubleshooting Common Issues

Problem 1: Device Cannot Find "KONNWEI" Bluetooth Network

• Ensure the adapter is powered on (check the front panel button).
• Verify that the OBDII connector is receiving power (should be 12-14V).
• Confirm that the vehicle's ignition is switched on.
• Try turning off the ignition, removing the adapter from the OBD-2 port, reinserting it, and then turning the ignition back on.
• Attempt to search for the Bluetooth network using another device such as a different smartphone, laptop, or tablet.

Problem 2: Adapter Disconnects During Operation

• Ensure that high-power devices are not being charged via the cigarette lighter while the adapter is in use, as this can cause voltage fluctuations.
• Strong voltage surges within the vehicle's electrical system can affect adapter stability. The OBDII connector typically outputs 12-14V.

Problem 3: Adapter Cannot Connect to ECU

• Some vehicle ECUs may require additional initialization codes for proper connection. These codes are often available within the scanner application's database for various car brands.
• Try using alternative scanner applications, as different apps may utilize different communication protocols with the ECU.
• Ensure that only one scanner application is running at a time to avoid conflicts.
• Attempt to reconnect by repeating the connection steps from the beginning (Step 1).
