Gids:

carcan msgId 5B3 : D5(?) & D6

Can someone who charges higher than 255 gids confirm the location of the MSB? It logically should be bit0 of D5 (D6 contains the LSBs).

TickTock, did you figure out how to get GIDs on the 2013?

I just looked at the log file we captured from your car - I am reading gids from the same location as on my 2011 (5b3:D5,D6). And I am sure I didn't get it mixed up with one of my own logs since I am reading 245 gids (I have not gotten that much charge since over a year).

Correct. D7 bits 7,6,5,4 are valid bits for the corresponding data byte (D3,D4,D5,D6).

Correct. D5[1:0],D6[7:0]

D3[7:0],D4[7:5]= Remaining Charge time (120v)
D4[4:0],D5[7:2]= Remaining Charge time (240v)

So just tried a few of Jim's gems on EV-CAN with mixed results (as anticipated based on the ELM thread)..

797/79A works fine (main vehicle controller?) so VIN, L2/L1 count, DCQC count come in fine as well (I'm sure) as a bunch of other goodies yet to be discovered.

792/793 (OBC?) doesn't work as anticipated, but probably because I'm on a 2013 at the moment and the OBC is built in.. so to speak. I'm guessing 792/793 for EVSE info will work fine on my 2012 which is fine because all we really want is ampacity for Brusa control on 2011 and 2012.

745/746 (traction control?) for tire pressure doesn't work :( So I guess CAR-CAN can reach through the VCU to EV-CAN but not the other way around. Bummer.. Maybe this info is reflected in the VCU data somewhere..

What is the message you send on 5B3 to get the GIDS?

You don't need to send any message. Message 0x5B3 is just there anytime the CAN-BUS is active. You just need to capture the message.

Thanks Turbo3. How do all these things translate to ELM? For example, I tried getting L2 count but I couldn't figure out what sequence was necessary to get the correct message sent.

And for GIDS, how do you even listen on the ELM w/o first sending commands?
