The two pins just left of “our” can pins are transmitting on +/- 4V. And on the far left side there are probably additional can pins. Could mean that the S is running multiple can buses (Roadster has 3 different can buses running). Somewhere I read that Model S also has a “BEAN Bus” (a Toyota specific standard running on a single wire - <a href="http://elinux.org/BEAN_Bus">http://elinux.org/BEAN_Bus</a>).

When reading the bus be sure to attach CAN HIGH, CAN LOW and CAN GROUND (you can use normal GND, see image). If you don’t use CAN GROUND, the car will get confused. The Roadster doesn’t care if you use CAN GROUND, but Model S seems to be a bit sensitive on this topic. Also be careful with the +12V pin. If you produce a short your instrument panel screen will eventually go black as they seem to share the same fuse (which is the 5A fuse #49 in fuse box #2). </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Ok, once all wires are in place and the car is still running, it’s time to read some data.
