CAN Bus - repeat last state

New to Arduino. My goal is to capture CAN Bus message from one particular ECU, and broadcast that same message upon power up of the Arduino.
Project: Detect the status of accessories turned on or off in a vehicle, and have the Arduino turn on or off those same accessories when the vehicle is started.

You have our permission.

Is there some part of that you need help with?

What have you written so far, or from what examples are you working, or what source of knowledge?

Have you made any of the hardware or connected to a CAN bus yet?

I don't use CAN but it seems straight ahead doable.

What does google turn up for similar projects? Perhaps it's been done, maybe even well done, sounds like a good idea.

Oh yeah, welcome to the fora.
