Rear Seat Belt Warning Light Malfunction [03/2017 - 10/2020]: Description

The main body ECU (multiplex network body ECU) detects whether either the rear doors are open or closed based on the courtesy light switch condition and then sends the rear door status signal to the combination meter assembly. The combination meter assembly detects rear seat belt state. The rear seat belt warning light on the telltale light assembly illuminates, blinks or turns off in accordance with the rear door state, vehicle speed and rear seat belt state.
