It works with cars and light trucks (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.)

Most OBD2 apps can only 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 OBDCheck BLE works with Android & iOS devices. Note: many Android head units are incompatible.

Normally you can leave it plugged in if you are driving the vehicle frequently. However, it’s always recommended to unplug the OBD2 device when it’s not in use.

A third-party OBD2 app is required (see above compatible app list). 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.

Try the following ways: disable and enable Bluetooth (most efficient way; try a few times if the first time does not work); restart your phone; turn off WiFi; clear Bluetooth cache/storage.

If it is paired with your Android phone, but stays connected for only a few seconds then becomes previously connected device, don’t worry, usually it’s still connected. You just start the app, and see if you can select it as the Bluetooth device to connect.

Please do not try to connect it through the iOS Bluetooth Settings. No regular Bluetooth pairing is needed for Bluetooth LE. Please directly connect in the app.

It reads standard SAE PIDs such as O2 Readings, EOT, EGT, Throttle, 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 or a capable App. Contact the app developer to verify if it’s supported.

Check if the device is powered on (blue LED light). 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: Bluetooth list for VEEPEAK.

Check the app compatibility and make sure the correct connection settings is made in the App. If it does not help, try the following: remove the app and re-install it; try with a different App.

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; try with another vehicle.

Please contact the app support in the app or through their website.
