2005 Caldina Ecu Interface

[Chris Nisbet]

I want to connect to my 2005 Caldina's ECU using my ELM327 interface. However, the populated pins on the interface socket don't seem to correspond with what seems to be normal for the OBD2 and/or CAN interfaces. The pins used (on the car) are 4,7,8,9,12,13,14,15. I have an ELM327 (based) interface that works fine on another car that has an OBD2 interface. From what I can tell, this interface box also supports CAN, but I haven't tried it on a car that uses this protocol. However, it doesn't work at all on my Caldina. Does anyone have any idea what the story is here? Do I need a special interface cable that swaps some pins around? Does the ELM327 not support the same protocol that my Caldina does? Am I doing something obviously wrong? Does the Caldina support some other protocol? If so, what is it? Like I said, I'm able to connect just fine to other cars that I know _do_ support OBD2, just not this one. I've spent a bit of time searching for something on the net that will clear this up for me, but haven't found anything specific to the Caldina. Thanks in advance.

Did you get anywhere with this? I've just purchased a Caldina ZT 2005, and thought I'd be able to use the ELM327 as well, but it won't talk to the ECU.
