Circuit / System Description
The instrument panel dimmer switch is used to increase and decrease the brightness of the interior backlighting components. The body control module (BCM) supplies a 12?V reference to the backlight dimmer switch, which is part of the headlamp switch. When the backlight dimmer switch is placed in a desired brightness position, reference voltage is applied through the dimmer switch rheostat to the BCM. The BCM interprets this voltage signal, then applies a pulse width modulated (PWM) voltage to the LED dimming control circuit to all related interior lamps, illuminating them to the desired level of brightness.
