Im working on a board to interface with the cars computer through the OBD2 port. I have this working on GM vehicles, I am able to lock, unlock, remote start, do blinkers and a bunch of other stuff from this board. Im trying to get this working with my car aswell.

Does anyone know where i can tap into the can bus on these cars? Im looking for wire colors, baud rate, and location of the wires.




Thanks!

 

it has 3 can bus systems
can c
can b
diagnostic can c

which one do you want to connect to?

 

Well im looking for control of the interior bus. Did you mean a, b or diagnostic c? Out of the three id say i don't want the diagnostic bus as that should be standard and accessible through the obd2 pins.

Thank you for the reply!

 

Controller area network or CAN

can B has a speed of 83.3kbps

it is wired in a stub configuration...with one CAN + wire and one CAN- wire from each module connecting to 2 main central lines.

the instrument cluster module or ccn serves at the bcm. the tipm is the gateway module that communicates on all 3 bus systems.
