I in turn launch into the experience on my vehicle : the new Peugeot e208.
The e208 is based on a new technical platform from the manufacturer, common for thermal and electric models. Perhaps even more specific on the electric for OBD, like any electric vehicle.
After a quick start / installation of the OVMS module, everything seems functional.
For the wiring, I share what I found:
On the OBD socket (located on the driver's side, remove the cover under the steering wheel on the left), only the pins 1,3,4,5,6,8,14,16 are wired.
The standard/regulatory CAN bus is on pins 6 and 14 (6: high, 14: low)
The Diagnostic CAN Peugeot bus is on pins 3 and 8 (3: high, 8: low)
pin 1 + 12v after power
pin 3 can high Peugeot
pin 4 body ground
pin 5 electro ground
pin 6 can high standard
pîn 8 can low Peugeot
pin 14 can low standard
pin 16 + 12v OBD
Can1 = regulatory/standard can
Can2 = pins 3 and 8 of the OBD socket must be re-mapped on connectors 13 and 12 respectively for OVMS
Then, I followed the recommendations from the article "General suggestions for adding support for a new vehicle to OVMS".
If the first two steps have gone well, I have a little more trouble for the rest ...
The connection with the 2 can buses seems to be well established. Very verbose data does arrive from can 1 (regular broadcast).
As advised, I use Savvycan to capture the data. I observe an evolution of the data according to the action launched on the vehicle (opening / closing, poweron / off, etc.) but I am unable to extract any concrete information from it.
OVMS does not seem to recognize any of the known standard PIDs, so I have no feedback in the dashboard (no Soc, no VIN, etc.).
The vehicle being very recent, I did not find any documentation on the internet, nor in the somewhat 'specialized' forums.
So I have a few questions, maybe I'm on the wrong track ...
- how to interpret the data collected in Savvycan? if I could identify real values, I would be able to deduce the function concerned.
- I suppose that can2 only responds on request from the OVMS, what type of tests or requests can I test to validate obtaining a response forme the can bus ?
- for all these tests, what is the appropriate setting for "vehicle type" in OVMS, I currently use "OBDII" ?
Please found here as an example a Savvycan capture, at the opening of the vehicle.
Thanks for your help !
