ELM327 USB CAN-Bus Driver Installation
The ELM327 OBD2 Interface incorporates all nine of the protocols in use around the world today. This includes the latest CAN-Bus protocol. The ELM327 Micro Chip is auto-sensing and auto-switching, that is to say when connected to a vehicle the interface will sense which protocol is in use and then switch to that protocol, thus allowing the software program to communicate with the vehicle.
A point to note is that not all OBD2 software is compatible for the ELM 32X chipset, for example VAG-COM software is not compatible.
As this is a USB device driver installation is important to ensure correct communications. Use the following pictures to ensure you install the driver correctly.

Windows will detect and then find it has no driver and so the driver installation will start.
