Display Dimming
The dimming of the indicator display is controlled by the pulse width dimmer module. The voltage on Pin 2 controls the brightness of the message center
display. When the exterior lamps are OFF, this voltage will be zero volts and the message center display will be at maximum brightness. When the
exterior lamps are ON, this voltage will be controlled by the pulse width dimmer module and will be between 2.5 volts and battery voltage. The
message center display will be brighter as this voltage approaches battery voltage. If there is a warning on the message center display, the display will not
dim to its lowest level.
When the headlamps or parking lamps are OFF, the display of the message center indicator will be maximum brightness and the labels for the center five
switches of the message center switch module will not be illuminated.
When the headlamps or parking lamps are ON, the brightness of the display of the message center indicator and the labels for the center five switches of
the message center switch module will be controlled by the pulse width dimmer module.
