OBD2 ELM327 Bluetooth Guide

Welcome to the OBDII LM327 Bluetooth guide App

The ELM327 is a programmed microcontroller produced for translating the on

board diagnostics (OBD) interface found in most modern cars. The ELM327 command protocol is one of the most popular PC-to-OBD interface standards and is also implemented by other vendors.

The original ELM327 was implemented on the PIC18F2480 microcontroller from Microchip Technology.

While in business, ELM Electronics also sold other variants of the product, with slightly different part numbers, which implemented only a subset of the OBD protocols.

【Excellent Compatibility】- Compatible with all Gasoline vehicles in OBDII interface, which support 9 OBDII protocols: 1.SAE J1850 PWM(41.6Kbaud) 2.SAE J1850 VPW(10.4Kbaud) 3.ISO9141-2(5 baud init,10.4Kbaud) 4.ISO14230-4 KWP(5 baud init,10.4 Kbaud) 5.ISO14230-4 KWP(fast init,10.4 Kbaud) 6.ISO15765-4 CAN(11bit ID,500 Kbaud) 7.ISO15765-4 CAN(29bit ID,500 Kbaud) 8.ISO15765-4 CAN(11bit ID,250 Kbaud) 9.ISO15765-4 CAN(29bit ID,250 Kbaud). (Not support Hybrid or electric vehicles)

【Suitable for system】-Mainly used with Android system phones, also supports Symbian system phones, Windows system PCs and laptops. Compatible App: Recommended Apps are Torque Pro, Torque Lite (free), OBD Car Doctor (free), etc. on Google Play.

【Smart Scanning】 Read diagnostic trouble codes, nonspecific and manufacturer-specific, and display their meaning (over 3000 code definitions in the database).

【Easy to Use】-Plug this OBD2 scan tool in your car's OBD2 port, turn on your car, enable Bluetooth on your Android phone or tablet, search for "OBDII" and pair with it (pin 1234), run the download App with simple settings and wait until it connects your car's ECU successfully

Save time and money by finding out why the check engine light is on and fixing simple car problems by yourself! Read and clear check engine trouble codes, Check Engine Light using your phone or tablet and an OBD2 App.

How to connect

Connect the ELM327 interface to the OBD-II adapter in your vehicle.

Start your vehicle or at minimum have the ignition switch on.

The OBDII plug is normally located under the steering column or dash board, about 3 feet away from the driver.

Locate and enable Bluetooth on your Smartphone or Tablet.

Click the Menu icon, click Settings, click Wireless & Networks, and finally click Bluetooth Settings.

Scan for and locate new hardware.

It may show up as 00:13:EF:00:0A:69 or similar but will resolve to OBD-II or similar.

If scan results come up empty, unplug the interface and plug it back in and be sure you in transmission range of the Bluetooth signal. If this continues, try it in another vehicle.

After the OBD-II Interface has been located pair it using the code “1234” or “6789”.

Install the ELM327 app of your choice.

We suggest Torque Free for Android, you can find this in Google Play.

Open the app and proceed to set the software up to connect to your OBD-II diagnostic tool. In Torque you will need to select the Bluetooth Device from the preferences menu.

Go Online with your vehicle to begin collecting real-time data and trouble codes from the ECU. The process for each software package will be different but is generally self-explanatory.
