ELM327 Bluetooth OBD2 adapters require a PIN code for initial pairing with your smartphone or tablet. This guide provides step-by-step instructions to successfully connect your ELM Bluetooth OBD2 adapter.
First, plug the adapter into your car’s OBDII port, usually located under the dashboard. Turn the ignition on or start the engine. If your adapter has a power button, press it.
Pairing Your Device with the ELM Bluetooth OBD2 Adapter
Step 1: Enable Bluetooth and Locate the Adapter.
In your phone or tablet’s settings, turn on Bluetooth. Your device will begin searching for available devices. Look for the OBD2 adapter in the list of discovered devices. The name will likely be “OBDII,” “obd2,” the brand name (e.g., “Viecar,” “VLink”), or a similar variation. It will not be named after your car’s make or model.
Step 2: Enter the Elm Bluetooth Obd2 Adapter Pin Code.
Select your OBD2 adapter from the list. The adapter will prompt you for a PIN code to complete the pairing process. Common default PIN codes include:
- 1234
- 0000
- 6789
- 1111
Consult your adapter’s documentation if these codes don’t work.
Connecting to Car Scanner App
Step 1: Access Adapter Settings.
Open the Car Scanner app and navigate to the settings menu (usually a gear icon).
Step 2: Choose Bluetooth and Select Your Adapter.
In the settings menu, select “Adapter” or “Connection” (depending on the app version). Choose “Bluetooth” as the connection type. Tap “Select device” to view available Bluetooth devices.
Step 3: Connect to the OBD2 Adapter.
Select your ELM Bluetooth OBD2 adapter from the list. You should now be connected. Return to the main Car Scanner screen and tap the “Connect” button. Subsequent connections should only require tapping the “Connect” button, provided your adapter’s power is on.
Remember to always consult your adapter’s manual for specific instructions and troubleshooting. With successful pairing and connection, you can utilize the Car Scanner app to diagnose and monitor your vehicle’s performance.
