Tesla PTC cabin heater // Model-S CAN4 logfile

Hi,

I got a Tesla Model-S PTC heater and would preferable control it by CAN. Does someone have a logfile of the CAN-4 bus of a model-S ? There are several logs around from the other CAN-busses, unfortunately did not find one of the CAN4 yet.

Alternatively I will modify the heater to accept a single PWM signal for controlling the IGBT's.

Hi,
Did you manage to get it working?
Do you have site or blog of your project :) since i'm from the netherlands too i'm very interested.

When you connect the device, which messages does it send out?
I will check if i can find something. I have something but i need to know what it sends out right now. :)

CANBUS is quite my playground :)

Did not connect the heater yet. The dimensions are larger as expected and it will be difficult to fit in my original BMW heater box. So I ordered some smaller (non-tesla) heaters, unfortunately not CAN-controlled (I assume LIN).
