OK... Here's the list of supported PIDs of the 2007 Prius

To find them I did the following CMNDS

XXYY where XX is the mode and YY {00, 20, 40, 60, 80, A0, C0, E0}. The return you get back is a bitmap letting you know which of next 32 PIDs are supported. If the return you get back is odd, then go ahead and advance YY by 20. I tried XX of 01-0F.

Example

0100: 4100981A8013 (odd, so keep going)
0120: 412080018001 (odd, so keep going)
0140: 4040FE1C2000 (even, so I can stop)

XXYY where YY := {00, 20, 40, 60, 80, A0} are PID support bitmask request.
---- where XX := {01, 06, 08, 09} the only responsive OBD-II modes on Prius II

I tested for Vehicle specific modes and the only bites I got was on $3F and $7F, but both of these seem to be reserved modes so it's unlikely to find Prius specific data there.

Talking to Ron of LinearLogic this evening he said that they have been able to retrieve enhanced data from the CAN Prius, including SoC. I am still surprised that you get nothing back from mode 0x22. It could be that the message ID format is different from what other manufacturers use, but I think they will figure it out.

Big cheers to Ron for snooping the CANbus. I'm hoping that they might be able to expose some of their CANbus snooping for XGAUGE. But then again, as with any SW release, eventually you have to draw a line in the feature list.

I justed edited OP to add decodes for the numeric mode/PIDs

Just trying to understand. Can the list of PID's be displayed by the SG? Any idea if there is a Fuel Level PID?

Well you can send the CMNDS to display the above. Fuel Level isn't supported though. Even some listed as "supported" aren't.

Fun to play with though.
