It’s known for its compact size and ease of use, aiming to provide “the power of information in your hands.” However, like any tech device, you might encounter situations where your Kiwi 3 OBD2 adapter “wont work” as expected. If you’re facing frustration with a non-responsive Kiwi 3, this troubleshooting guide is here to help. We’ll explore common reasons why your Kiwi 3 might not be functioning and provide step-by-step solutions to get you back on track.

Common Reasons Why Your Kiwi 3 OBD2 Might Not Work

Before assuming a major fault, let’s consider some typical culprits behind a “Kiwi 3 Obd2 Wont Work” situation. Often, the issue is minor and easily resolvable.

1. Connection Problems at the OBD2 Port

The most basic step is to ensure a proper physical connection. The OBD2 port, usually located under the dashboard on the driver’s side, might be obstructed or have loose connections.

• Adapter Not Fully Seated: Ensure the Kiwi 3 is firmly plugged into the OBD2 port. It should be securely fitted without being loose.
• OBD2 Port Damage: Inspect the OBD2 port for any visible damage or bent pins. A damaged port can prevent proper communication.
• Obstructions: Check for any debris or obstructions in the OBD2 port that might prevent a secure connection.

2. Bluetooth Pairing Issues

Kiwi 3 relies on Bluetooth to communicate with your smartphone, tablet, or PC. Pairing problems are a frequent cause of connection failure.

• Incorrect Pairing Procedure: Kiwi 3 typically doesn’t require traditional Bluetooth pairing through your device’s settings. It connects directly through the compatible app. Ensure you are using the correct app and following its connection instructions.
• Bluetooth Disabled: Verify that Bluetooth is enabled on your smartphone or device.
• Interference: Other Bluetooth devices nearby might interfere with the connection. Try disconnecting other Bluetooth devices temporarily.

3. App Compatibility and Settings

The Kiwi 3 adapter requires a compatible app to function. Using the wrong app or having incorrect app settings can lead to connection problems.

• Incompatible App: Ensure you are using a Kiwi 3 compatible app. PLX Devices offers the “Kiwi OBD” app, and Kiwi 3 is also compatible with many third-party OBD2 apps. Refer to the Kiwi 3 support page for a list of compatible apps.
• App Permissions: Check that the app has the necessary permissions (Bluetooth, location if required) on your device.
• Outdated App Version: Ensure you have the latest version of the app installed. Updates often include bug fixes and improved compatibility.
• Incorrect App Settings: Within the app settings, verify that Kiwi 3 is selected as the adapter and the communication protocol is correctly configured (usually automatic is best).

4. Firmware Problems

Although less common, firmware issues can sometimes prevent the Kiwi 3 from working correctly.

• Outdated Firmware: Check if there are firmware updates available for your Kiwi 3. Firmware updates can improve performance and fix bugs. The update process is usually done via Bluetooth through a compatible app.
• Firmware Corruption: In rare cases, firmware corruption can occur. Refer to the manufacturer’s website for instructions on firmware recovery or reset if available.

5. Vehicle Compatibility

While Kiwi 3 is designed to be compatible with all standard OBD2 protocols, there might be rare instances of vehicle incompatibility.

• Non-OBD2 Compliant Vehicle: While most vehicles from 1996 onwards are OBD2 compliant, it’s worth double-checking, especially for older or non-US market vehicles. You can check vehicle compatibility here.
• Vehicle-Specific Issues: Some vehicles might have unique communication protocols or electronic configurations that could, in rare cases, interfere with OBD2 adapter functionality.

6. Power Issues

Although Kiwi 3 is designed for low power consumption, power-related issues can sometimes arise.

• Vehicle Battery Issues: A weak vehicle battery might not provide sufficient power to the OBD2 port.
• Kiwi 3 Malfunction: In very rare cases, the Kiwi 3 adapter itself might have a power malfunction.
