I am looking at another problem ATM.
I am trying to have anything OBD2 hooked up to my Monster 1100 EVO, and everything I tried seems to fall flat.
The FIAT 3PIN (in my bike, there are actually two lead cables, not three) do not show any activity, both when using the KKL 409 cable and when using one of the ELM327 based ones.
I am using the FIAT 3PIN to OBD2 adapter with the two extra GND,+12V cables.
First thought, cables are junk (fine Made in China crapware).
The ELM327 talks to me using minicom on Linux, so at least the serial USB part of the circuit is fine.
But no matter how I tried (trying any kind of ELM327 protocol/initialization), the other side seemed dead.
I then remembered that my Camaro 2SS has an OBD2 port, so I plugged the ELM327 cable there, and I am indeed able to see traffic.
So cables should be fine IMHO.
A little bit of Google Fu revealed that the port where I plugged the FIAT 3PIN adapter under the seat, is not even supposed to be there.
I do not have the service manual for my 1100 EVO, but I have been told a recent 696 one is pretty similar from an electrical POV.
Here it is:http://img26.imageshack.us/img26/9421/m696schemaelettrico.pdf
There is no mention of such port, and the way the 696 service manual talks about it, it seems that both DDA and DDS need to be plugged into the DDA port.
After a little bit of digging in Italian forums, I have found that the DDA adapter for 696/1100 EVO (at least) are FCI brand, with these codes:
Even though if the connector looks like to be a Tyco, no one seems to have been able to find the matching part, and the FCI has been reported to be matching.
Looking at the wiring diagram above, these are the connections from the DDA port to the power/ECU (looking at connector from front, latch on the upper side, left to right):
3) ECU B1 pin / CAN Hi
4) ECU C1 pin / CAN Lo
And this is the M3C ECU connector pin out as coming off the service manual:
Would be nice to know what these B1 and C1 pins map into the ECU, but looking at this sheet, it looks like these are CAN signals:http://www.freescale.com/webapp/sps/site/taxonomy.jsp?code=S12S12X
So my next step is to try to get an FCI connector, and hook the pin #3 and #4 to my ELM327 to see if it sees anything.
Having an oscilloscope would help, but I do not have one (maybe it is time to buy one
