How to Install ELM327 Bluetooth OBD Scanner on Android Phone/Tablet

This article will guide you how to pair ELM327 Bluetooth OBD Scanner to your Android device.

It will then successfully work with any OBD App.

FACT: Android Apps vs. Windows OBD Software
If you’re a professional mechanic, auto technician or a series DIY’er — then we highly recommend you get professional Windows based OBD software. Because while Android apps are convenient — they are still years behind proper advanced OBD2 and ECU performance tuning software offered only on Windows, like TOAD.

STEP 1: Plug ELM327 Bluetooth into Car’s OBD Port

insert elm327 into car

Car’s OBD port is usually found on the driver side dashboard under the steering wheel.

Can’t find it? Locate it here.


STEP 2: Turn ON Car Ignition

This is one step before engine is powered.


STEP 3: Pair ELM327 Bluetooth

On your device — go to “Settings” > “Bluetooth”. Connect to Bluetooth signal with name similar to these examples: OBDII, ELM327, VLink, Can OBDII, etc.

NOTE: It can take up to 30 seconds for Bluetooth signal to show.

Pair code: 1234

If above doesn’t pair, then: 0000





STEP 4: Configure OBD App To Detect Bluetooth

Launch your OBD App. (We put together a list of best OBD apps here.)

Go to Settings and configure it to look for Bluetooth. (See this article demonstrating settings we had to change in “Torque LITE” for it to connect. Same principle applies to any OBD application.)


STEP 5: Connect To Your Car

OBD App should now successfully connect to your vehicle.

NOTE: If OBD App still doesn’t detect the Bluetooth connection — then force quit the app and launch it again. (To force quit inside Android, use “Task Manager”.)
