Hello salvage Tesla people,
@rooter -- thank you for your open-sourced work! I'd be happy to contribute to your wiki once I gain more knowledge.
I don't have a Tesla on my hands but I've got a LDU that I want to control over CAN, and later I want to mess with a small RDU.
However it seems like there are lots of different firmware versions, some of which have different communication protocols or listen to different messages on the bus.
So I want to deploy firmware to my DU using another Tesla (model S) and the firmware-redeploy over Telnet. That way I can just log CAN from that Tesla and be sure the protocols match.
I'm not sure when a redeploy works. I read through this thread
Manual firmware update (for new charge port) -- does a redeploy work only when the car is on latest firmware, or can it be done with any vehicle (salvage possibly?)
I was thinking of running a redeploy in a car and just recording the CAN3 (powertrain) traffic, then playing the record back at my LDU.
Also if a record and playback doesn't work I could theoretically disconnect the DU in the car and hook up the external one, then redeploy again.
Has anyone tried something like this? Any tips or tricks?
Alternatively, does anyone have CAN3 logs from an S?
(Also I hope this is a good place to ask -- I'm new here[but not new to EVs] and there seems to be a LOT of knowledge in this thread).
Thanks!
