COMBINATION METER ILLUMINATION CONTROL
Daytime Mode
When ignition switch is turned ON, combination meter il lumination is turned ON by unified meter control unit.
Nighttime Mode
 Unified meter control unit is transferred to nighttime mode, with ignitio\
n switch turned ON and position light
request signal from BCM with CAN communication.
 When nighttime mode, illumination c ontrol switch illumination turns
ON by unified meter control unit. Each illumination is controlled by
unified meter control unit.
 Each illumination can be adjusted to 16 step by illumination control switch in nighttime mode.
NOTE:
For further details of illumination circuit, refer to LT-169, "
