The Local Interconnect Network (LIN) Bus consists of a single wire with a transmission rate of 10.417 Kbit/s. The serial data is transmitted over a LIN circuit between a master control module and other LIN devices within a particular subsystem.

The Diagnostic Trouble Code (DTC) will set when a supervised periodic message to Headlamp Control Module/Headlamp Leveling Control Module from Right Headlamp has not been received.
