I have an ELM327 Bluetooth, which I'm linking to ubuntu powered PC. My end goal is to install a raspberry pi into the car and have it automate things like automatically opening the roof and locking the doors when the vehicle reaches a certain speed. Also, turning on the headlights would be nice(based on a light sensor connected via GPIO). I'm attempting to follow http://theksmith.com/software/hack-vehicle-bus-cheap-easy-part-2/ , but I'm stuck at the identification part. I can't seem to find a single message for each action, and transmitting the messages back into the canbus seems impossible to achieve even with the help of the command list. If there's a list of commands for the Honda Jazz 2009 it would be great.

I may be wrong, but as far as I am aware, the bluetooth ELM327 interface only supports the OBD2 standard, so CANBUS operations aren't possible.

  • Can operations are included in the AT command sheet though( sparkfun.com/datasheets/Widgets/ELM327_AT_Commands.pdf ). I'm open to any other method of communicating though? – Wilhelm Erasmus May 11 '15 at 12:17
  • Yeah, but I don't think the Bluetooth adapter supports this. Especially not if it's one of the generic ELM-scan/OBD-Scan ones like I have. I had to buy a Tactrix cable to gain access to advanced functions in my Subaru. But I might be wrong. As far as I am aware, you'd need a specialised CAN-Bluetooth adapter, rather than OBD-Bluetooth. That being said, check out this link: kickstarter.com/projects/etx/… – Captain Kenpachi May 11 '15 at 14:03
