AFAIK, the Volt uses raw CAN, too. The ELM-based products have no problem accessing the primary bus on the Volt. The real issue is that they cannot access the other buses (e.g. SWLAN, DWLAN on pins 12-13), but most tools cannot access those.<br>
<br>
The reverse engineering tool sounds very, very nice.<span class="HOEnZb"><font color="#888888"><br>

I, and others, have also had success with CANUSB (<a href="http://www.canusb.com/" target="_blank">http://www.canusb.com/</a>), but that is more expensive that the ElmScan 5 approach.<br>
<br>
I originally used a cando (<a href="http://www.cananalyser.co.uk/" target="_blank">http://www.cananalyser.co.uk/</a><u></u>) which is similar but windows-only.<br>
<br>
These are both CAN tools (not ODBII, but ODBII builds on CAN for modern cars).<br>
<br>
If you want to do anything custom, the CANUSB is pretty cool. It appears to the operating system as just a USB serial port, with textual protocol, so i easy to script from in Windows, Linux or Mac OSX.<br>
<br>
The ElmScan 5 is also possible if you just want ODBII, but note that the Tesla DIAG port is raw CAN not ODBII.<br>
<br>
I'm working on a project called CAN-RE-Tool that supports the CANUSB. It is designed for reverse engineering can buses. Getting real close to a first pre-alpha release, as I know Michael is waiting on it...<br>

Hi David,<br>
<br>
There are a number of different cables that should work.<br>
<br>
I use the ElmScan 5 (at Amazon, it is under US$30). The OBDLink SX (~US$50) is another good choice.<br>
<br>
The ElmScan 5 uses the ELM327 chipset, which cannot handle a connection to the computer higher than 500kbps, which sometimes causes a small amount of data to be lost. Also, the ELM327 chipset has an issue where it sometimes does not record all the data (if the first byte of data is between 1 and 8, it only includes that number of bytes of data, even if there is more). I believe the OBDLink SX (which uses a different chip that is compatible with the ELM327) doesn't have those issues.<br>
<br>
If you are planning to do more with the ODB2 port, there are lots of other options (e.g. ones that display data on a screen for you).<br>

Hi,<br>
<br>
I've just signed up here so it will probably take me a while to get up<br>
to speed on the work done so far.<br>
<br>
First off, can you advise me on what cable I need to obtain to pull logs<br>
(I saw RScott's program link) and also where to buy one?<br>
<br>
<br>
Thanks,<br>
<br>
David<br>
