Lin Bus
WARNING: This page is about a different car, the 2009 Land Rover Range Rover, 2008 Land Rover Range Rover, and 2007 Land Rover Range Rover. However, it is still accessible from the selected car via links, so may be relevant.
The LIN bus is a low speed broadcast network that employs master and slave components. The master component transmits a message along a single wire to the slave components identifying which slave is to respond. The message has a header (slave identifier) and an empty data field. The identified slave component fills the data field with the relevant information and returns a message to the master component along the same wire.
