DESCRIPTION
If the dimmer switch is turned to TAIL, HEAD or AUTO, the main body ECU sends a TAIL relay signal, panel light illumination signal, panel relay signal and TAIL cancel OFF signal to the combination meter. Then the meter and accessory meter become dim.
HINT:
w/ TAIL Cancel Switch:
When the headlights are illuminated and the TAIL cancel switch is turned on, the meter does not dim.
