Circuit / System Description
The instrument panel lamp dimmer switch is used to increase and decrease the brightness of the interior backlighting components. The instrument panel lamp dimmer switch provides a voltage signal that will increase as the brightness of the lights are increased and decrease as the brightness of the lights are decreased. The body control module (BCM) provides a low reference signal and a B+ voltage reference to the instrument panel lamp dimmer switch. When the instrument panel lamp dimmer switch is placed in the desired position, the dimmed voltage setting is applied from the instrument panel dimmer switch through the instrument panel lamp dimmer switch signal circuit to the BCM. The BCM interprets the signal and applies the dimmed voltage to the instrument panel lamp lamps supply voltage circuit and the interior backlighting components dim to the requested level.
