A large percentage of the automobiles produced today are demanded by the law to provide an interface for the connection of the diagnostic test equipment, the OBD (On-Board Diagnostics). The data transfer on these interfaces follow many standards but, there is no interface that provides a direct connection to the PC or the smart devices. Therefore, ELM 327 has been designed to act as a bridge between the On-Board Diagnostics ports and the standard RS232 serial interface.

The latest ELM 327 is the ELM 327 V 1.5 which is capable of interpreting and auto-detecting the nine OBD protocols and provides support for very high speed communications, a lower sleep mode and the J1939 truck and bus standard. It is also customizable in case you need to alter or change it in order to suit your needs.

ELM V 1.5 OBD-II car scan tool has a baud rate ranging between 9600 and 38400.

The type of indicator LEDS its uses are the OBD RS232, Tx/Rx and the Power.

It is featured by the nominal idle current rated at 45 milli amperes.

The USB cable the OBD-II ELM car scanner has a length of about 1.4m!

The vehicle speed and intake manifold pressure

The air temperature intake and the calculated load value.

The air flow rate and many others

Remember that these OBD scan tools device need ultimate care despite its numerous advantages.
