ELM329 CAN Interpreter Description Since 1996, most vehicles have been required to monitor their own emissions performance and to report on it through an On-Board Diagnostics (OBD) port. Initially, several different protocols were used for the transfer of OBD data, but since the 2008 model year (in North America), only one protocol has been allowed - the ISO 15765-4 CAN standard. The ELM329 is a device that can translate the data from an ISO 15765-4 interface into a form that may be readily used by computers, smart phones, or other devices. In addition, the ELM329 provides support for several other CAN protocols (including the SAE J1939 truck and bus standard), and for sending periodic messages, mixed ID messages, and for monitoring the CAN bus, to name only a few.
