Using OBDLink SX to Log the LEAF's CAN buses

[garygid]

Yes, makes sense, and does not risk destroying the OBDLink SX.

However, the connectors are well molded, and might be difficult
to dig into for modification.

I am considering mounting 3 panel-mount OBD2 female sockets
on a small box and wiring each one for one CAN bus.

I successfully logged the LEAF's CAR-CAN bus using the
ScanTool OBDLink SX device today, using my v196 of
CAN-Do.

I used 500,000 baud after a series of "AT" commands
to setup the OBDLink to output all the CAN Messages
in a MMMD1D2D3D4D5D6D7D8<LF> format, receiving
over 1000 messages per second.

I verified that the Accelerator Pedal Position value
was found in the expected message.

It seemed to work quite well, but the LEAF was only in
AUX-2 mode, not READY, and not actually driving.

Gary - did you incorporate these modifications into CAN-Do itself (the modified AT initialization strings, etc.)? If not, what program did you use with the OBDLink SX to do the actual datalogging?

I ask because I picked up a PLX KIWI, which (I think) is ELM327-based, and I'm trying to figure out if I should be able to use it with CAN-Do, or EasyObdII or some other Windows-based software. I'm actually trying to use it with the Torque Android app, but am having no luck thus far - it might be due to the LEAF's lack of OBD-II compliance and it not responding to an initialization string that Torque runs at startup.

Do you mind sharing the AT string you used to configure the OBDLink SX?

CAN-Do has the AT initialization strings, mostly sent manually,
but enough to get you logging. Start with this

However, I probably have a later version, but try this for starters.

A later version is

You are welcome to try it, but
right now I do not remember the differences.
