Im new in this forum. I'm working on a remote fleet management project to locate vehicles via GPS. Actually i have a gps tracker from falcom company installed in a vehicle that sends its location to a server. Falcom devices allows to read data from canbus and i would like to add new functionallities to my application in order to send fuel level or rpm trhough gprs to my server.
The main problem is how to start:
- How to connect falcom devices to canbus. I assume that through OBD2 connection there are 2 pins (Hi and low) for can bus. I would like to try it in my car (nissan 2009). Will it be as simple as connecting 2 wires to corresponding pins 4 & 16?
- About canbus messages it seems to be top secret for each manufacturer. I've heard that is possible to put an sniffer to can messages but i think that this could be impossible to obtain waht I want (for example fuel level)
- OBD2 has standard messages that are enough for me but can bus pins of OBD2 connector sends messages in OBD2 standard format or are manufacturer design?
Thanks a lot.
