difference between OBDII, CAN, VAN
Hi.
I am wondering what the difference is between these 3 busses,
I own a Citroen C3, and i would like to measure the Speedo and RPM gauge "real-Time" would OBDII be significant to do that, while also taking care of everything else..?
i would also like to know for ex.
which doors a open?
is the head light low and high beam on/off
what is the cunsumbtion
and so on..
which of the busses would i need to do those things..?
and can anyone give me an idea what the different busses does?
Thanks
