It works with vehicles (including hybrids) sold in the United States in or after 1996. Vehicles in other regions that are OBD II / EOBD / JOBD may also be supported (Canada – 1998, European Union – 2001 (gas), 2004 (diesel), Australia – 2006 (gas), 2007 (diesel), etc.)

The OBD2 devices are normally designed to read check engine light. However, enhanced diagnostics on selected makes and models are also available when using the appropriate application. Please check with the application developer.

The VP01 is compatible with iOS & Android phones and tablets. For Android, be sure to change connection method to WiFi.

We do not suggest that you leave the WiFi version plugged in if it’s not in use. WiFi consumes significantly more power than Bluetooth.

A third-party OBD2 app is required to work with our wireless OBD2 devices. There are free and paid ones and some apps provide in-app purchase. Please check the product page for compatible apps and the app page for more information about the features and prices.

O2 Readings, EOT, EGT, Throttle, Boost, Speed, Fuel Trim, DPF Temp, Balance Rates and more.
Remember readable parameters depend on what’s installed on the OBDII system by the manufacturer. Generally, newer vehicles will give more readings and faster refresh speed. Please also note that more sensors you have on the list the refresh frequency is lower due to limited vehicle bus/OBD device throughput. Some readings like transmission temp are manufacturer-specific and you will need the custom PID. Contact the app developer to verify if it’s supported.

Check if the device is powered on (it should become warm after being plugged in). If not, check the cigar fuse of your vehicle. If the device is powered on, make sure you are using a compatible phone/tablet and seeing the right place: WiFi list for WiFi_OBDII.

Check the app hardware compatibility first. Then make sure the ignition key is at ON (or start the engine) and the correct connection settings is made in the App. Fully quit the app and re-start it to connect again.

Verify if your vehicle is OBD2 compliant and the ignition key is at ON (check the car manual for the right mode for diagnostics or just start the engine). Check if the OBD II connector is in good condition: no bad pins or wires, no corrosion. If it works with another vehicle, submit the connection log in the app so the app support can further check.

If you are using an Android device, there is nothing to do to help for the moment.
