Local Interconnect Network (Lin) Bus
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2009 Jaguar XKR, 2009 Jaguar XK8, 2008 Jaguar XKR, 2008 Jaguar XK8, and 2007 Jaguar XKR. 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 to the slave components identifying which slave is to respond. This 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 the message to the master component.
Unlike the CAN bus networks, the LIN bus utilizes a single wire network.
