Hi,

I´ve hacked some messages from the confort can bus (Volkswagen):

RPM:



Window Control:


The example is a time control, but I´ve the position feedback message. And another more like clock, central locking, ....

(at the moment, it´s in spanish. The google translator works quite well).

Regards,

The next step is connecting to the Traction Can Bus, which you can get 4 wheel speed, yaw, gLat, throttle position, etc....
The confort one, it´s interesting because you can control windows, locking, etc. You can implement the typical security feature that some cars have like when you are more than a certain among of speed, all the doors are locked (it´s just an example).

My main objetive is data acquisition with a good display and some math channels, but one time you are connected, who could resist don´t try to control some stuff??? hehehe

Igor,

I have an arduino UNO r3 and the 10039 can bus shield with an obd2 to db9 cable. I have mounted the shield onto the arduino. At first I wasn't getting anything from the system but then I disconnected the reset pin header and things are transmitting better now.

I still can't get any info from the car though. I haven't found a good program that would allow me to interpret can signals. Please help. How are you able to see the RPM's? Do I have my setup wrong? I have a 2006 passat btw. I have found a lot of info about the CAN network in the car I just can't access it!

Thanks, rob

I believe you will have to access the canbus from somewhere other than the obd connector.  I access my comfort bus from behind the radio in my VW.  In my car I also have a infotainment bus although most of the information I want resides on the comfort bus.
