The ELM327 is a programmed microcontroller produced by ELM Electronics 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.
Cheap OBD2 Communications on K-line (ISO 9141-2 and ISO 14230-4): This is just another OBD2 solution for monitoring the sensors in a verhicle. It supports the K-line OBD2 serial communication between a verhicle and a microcontroller.
The original ELM327 is implemented on the PIC18F2480 microcontroller from Microchip Technology.
ELM327 is one of a family of OBD translators from ELM Electronics. Other variants implement only a subset of the OBD protocols.
Uses[edit]
The ELM327 abstracts the low-level protocol and presents a simple interface that can be called via a UART, typically by a hand-held diagnostic tool or a computer program connected by USB, RS-232, Bluetooth or Wi-Fi. New applications include smartphones.
There are a large number of programs available that connect to the ELM327.[1]

Protocols supported by ELM327[edit]
The protocols supported by ELM327 are:[2]
ELM327 command set[edit]
The ELM327 command set[3][4] is similar to the Hayes AT commands.
Other Versions[edit]
Typical cheap ELM327 copy without label on the controller
The ELM327 is a PIC microcontroller that has been customized with ELM Electronics' proprietary code that implements the testing protocols. When ELM Electronics sold version 1.0 of its ELM327, it did not enable the copy protection feature of the PIC microcontroller. Consequently, anyone could buy a genuine ELM327, and read ELM's proprietary binary microcontroller software using a device programmer. With this software, pirates could trivially produce ELM327 clones by purchasing the same microcontroller chips and programming them with the copied code.[5][6] ELM327 copies were widely sold in devices claiming to contain an ELM327 device, and problems have been reported with the copies.[7] The problems reflect bugs that were present in ELM's version 1.0 microcode; those making the clones may continue to sell the old version.

Although these copies may contain the ELM327 v1.0 code, they may falsely report the version number as the current version provided by the genuine ELM327, and in some cases report an as-yet non-existent version.[8] Released software versions for the ELM327 are 1.0, 1.3a, 1.4b, 2.1 and 2.2 only.[9] The actual functions of these copies are nonetheless limited to the functions of the original ELM327 v1.0, with their inherent deficiencies.

Iso 9141 2 Code Meaning In Urdu
This is just another OBD2 solution for monitoring the sensors in a verhicle. It supports the K-line OBD2 serial communication between a verhicle and a microcontroller. This K-line communication is also known as ISO 9141-2 or ISO 14230-4 (also known as Keyword Protocol 2000 or KWP). Both ISO's are almost similar. This solution differs from the rest that is low cost (for less than 10 euro!!). It is low cost in the way that you don't need an arduino, raspberry pi or smart phone. Just a microcontroller and LCD display so you can use your smartphone for other purposes.

Main features:
Engine Code Iso9141
To do:
It is tested with a Citroen C1 gasoline (2013) and VW Touran gasoline (2003). Probably it will work for a Peugeot 107 and Toyota Aygo of 2013 as well since they are technically identical. From what I read on the internet there are many flavours on K-line around so there is a possibility it will not suit your car. Maybe some changes are needed to make it work. The source code is provided so you can investigate and change when needed. Maybe you can help extending this list of cars to help others!
Have fun!
