Can bus interface (with a car module)

HELLO ALL, BEAN,
··· I want to use my sxchip to interface with a module in a car.· The module is called a PSE module and it controls the door locks through CAN technology.· Is there any way to read this, then send a value back.· If so how would I go about doing this?· What's an example program of reading this, and maybe an example hookup?· Any information would be appriciated.
I am not sure the speed of transfer, It should be a low speed transfer rate.·
How would the value look?· Like 0101000 or in wave length only?
Thanks again!
