I'm trying to read my cars CAN BUS data so i can use it to control a few relays and PWM SSR. I have a CAN BUS sniffer connected to the Arduino and the ECU Via the twisted can wires along with the 120 ohm resisters.
I cant seem to receive any data, does anyone have a proven program or link to one and it corresponding library.
Once I get the CAN data such as speed and gear position it will allow me to to control the power steering and clutch valve. (Among other things)
