Hello OVMS creators, I'm new to the group, but some of you know me already. I'm doing crazy things with a Model S and a VW camper which you can see via the link in my sig. I'd love to have service access to the Model S similar to what the service techs have with the TDS software. Without that tool I can't even bleed the brakes or cooling system. I don't like the idea of trailering my out of warranty vehicle to a service center every time I need to do simple maintenance. I realize that kind of access may never happen, but I figure I have to start somewhere and I assume that would be sniffing the CAN bus. As a small start in that direction I wanted a connector for under the center console with all the pins populated. Mark was kind enough to offer the parts: 173631-1 and 173851-2 which are not common and in stock in the US. I had already found that it looks just like the car side stereo connector for Mazdas from the 1990's and those can be had on ebay for $6 delivered so I bought a couple. http://www.ebay.com/itm/330520850374?item=330520850374&viewitem=&sspagename=... They arrived today, and though the quality seems poor and the fit is snug, the connector does fit. The other non matching connector can be used for extra terminals to fill out all the holes, but getting them out without damage is a challenge without a proper tool. It's clear that you all have already made great discoveries in EV monitoring and control. I'm looking forward to sharing what we learn here. -Otmar Otlist09@evcl.com Stretchla Project: http://cafeelectric.com/stretchla/ Zilla Support is still at: http://cafeelectric.com/Ssupport.php
Hi Otmar Great to hear that you're working om Model S too. Here is my progress so far (a copy of a mail sent some days ago):
Well here are some details:
The bus connector is located underneath the touch screen (grab the storage shelf hole and pull STRAIGHT down).
The connector is the same as in the Roadster. When reading the bus be sure to attach CAN HIGH, CAN LOW and CAN GROUND (you can use normal GND, see image). If you dont use CAN GROUND, the car will get confused. The Roadster doesnt care if you use CAN GROUND, but Model S seems to be a bit >sensitive on this topic. Also be careful with the +12V pin. If you produce a short your instrument panel screen will eventually go black as they seem to share the same fuse (which is the 5A fuse #49 in fuse box #2).
Ok, once all wires are in place and the car is still running, its time to read some data. Bus speed is 500 Kbit/s (vs. 1Mbit/s in the Roadster).
A fist quick look at the data showed me the following:
ID 2C8 looks like the actual charge settings.
67 32 = min Standard 67 5A = max Standard 67 63 = one tick before max Range 27 64 = max Range
Obviously the second bit bit represents the percentage of the charge settings (32h=50dec=50%, 64h=100dec=100%). It seems to be a readout only variable, as sending messages to ID 2C8 didnt change the charge settings.
Keep us updated about your progress!

Hi Ottmar, nice to have you her. Hope we can help you to find what you want. Bye Michael J. BTW: We are still in contact via Marco with the salvage TR. He is the guy (German) who try to fix the PEM. Thanks for your IGBT Tester Information. Am 12.01.2014 um 03:42 schrieb Otmar Ebenhoech <Otlist09@EVCL.com>:
