View source for LIN-BUS sniffing

Some low-priority functions can be executed by a slave module connected to LIN-BUS. For example [[RLHS]] module, ambient lights, interior alarm sensors, steering wheel buttons, battery monitoring module...

I'm going to use USB-to-LIN module (TJA2021T) to sniff on the LIN-BUS with my computer. And once I know what's going on over there, I can switch to UART-to-LIN (TJA1021) module and Arduino board to create some kind of custom controller.
