BCM transmits a meter ring illumination request signal to the illumination meter when all the following opera-
tional conditions are satisfied. When receiving the meter ring illumination request signal from BCM via CAM
communication, the combination meter increases illuminat ion brightness of the combination meter to the set
brightness level in stages. After a certain period of time, the meter illumination gradually dims to be turned
OFF.
