Abstract
A vehicle interior lighting system that performs LIN communication. The vehicle interior lighting system includes plural lamp units connected by a single bus cable, and a host ECU that is connected to the bus cable and controls operation of the plural lamp units. The host ECU transmits a fail-safe operation instruction signal to the plural lamp units after transmitting an operation instruction signal to the plural lamp units. The plural lamp units, when receiving the operation instruction signal properly, operate according to operation instruction information included in the operation instruction signal and ignore the fail-safe operation instruction signal and, when failing to receive the operation instruction signal properly, perform a fail-safe operation according to fail-safe operation instruction information included in the fail-safe operation instruction signal.
