Meter Illumination is Always Dark: Description

The meter ECU receives signals from this circuit to adjust the illumination of the meter. The meter ECU sets the illumination level based on the user operation of the light control rheostat switch.

HINT: 

• The meter illumination level can be adjusted by operating the light control rheostat switch.
• The meter illumination dims when the light control switch is turned to the tail, head, or AUTO position.
• Setting the meter illumination to maximum brightness cancels the above dimming of the meter illumination.
