The OBD2 WIFI version makes use of the OBD2 WIFI Code Scanner to get information from your car’s computer through the use of your PC and a hardware interface. And although all devices that have employed the use of OBD2 WIFI Adapter still don’t really hold the candle to professional scan tools, they actually do put so much information in the DIYers hands. The tiny program was developed to help bridge the gap that was created by the original simpler devices which were used to read, diagnose and clear codes but unfortunately could not give any access to the PIDs that are very useful in diagnosing all forms of power problems among other automotive issues. Generally, OBD2 WIFI functions more or less as a bridge between the On-board computer in your car and your PC or any other compatible handheld device, communicates with the OBD2 systems and then relays data either via Bluetooth, WiFi or BLUETOOH, depending on the implementation. In fact, it has become one of the most popular and practical PC-to-OBD2 interface standards that are implemented on the PIC18F2480 micro-controller from the Microchip Technology. It is used to translate the OBD2 interface that is found on most modern cars. The OBD2 WIFI Adapter is a one of the latest programmed microcontroller and a scan tool produced by the ELM electronics that is compatible with all the OBD2 protocols such as VPN, KWP, PWN and CAN.
