Wow... this is quite the first post... and from an 11 month old account too?

Regardless, thanks!

More details, please!

ORIGINAL COMMENT: Does this handle all VSP sounds, e.g., slow-speed as well as the backup beep?

UPDATE: I didn't scroll down in the box to see all the comments where you documented exactly what I asked.

Should/could this go into LeafSpyPro?

Reprogramming this through leafspy would be awesome!

Great, how does one go about sending these commands? Is there a serial interface somewhere?

Probably. IIRC, one controls these ELM327 devices via commands like Hayes (modem) AT commands. I remember the old days of coming up w/the "optimal" init string for some modems.

Can the duration/# of repeats/cycles of the reverse noise be turned off (e.g. 3 to 5 chimes, a single chime or 5 seconds worth)?

Good find. Thanks for reporting it.

Coincidentally I just collected data from my neighbors 2016 Leaf last Tuesday which included a sequence to turn off VSP and test all the various sounds. But I had not yet had time to look at the CAN trace data to see what the actual sequences were and still have not looked at the data.

But the 3B xx xx is the right command group to do such things and 0x73f is the VSP ECU address.

At some point I will include this function in LeafSpy Pro. Probably as an option in Settings where you enable "Disable VSP sound on startup".
