How do i increase the back light. IT has gone dimmer while setting clock

. The illumination is controlled by the BCM - body control module .
Interior Lamps Dimming
This group includes lamps which may dim. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps.
• HVAC control module, head assembly
• Rear HVAC control module, head assembly
• Radio
• Rear seat Audio
• The instrument panel cluster (IPC)
• The PRNDL lamp, with the exception of the current gear select position
• Power window switches
• Various switches
When the ignition switch is turned to the ON position, the VF display, radio, turns ON at maximum brightness. When the park lamps are ON, all incandescent back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. At the same time all VF displays dim to match the indicated dimming level. When the headlamp switch is placed in the PARK position, the park lamp supply voltage circuit provides an input to the body control module (BCM). The BCM then supplies voltage to the I/P dimmer switch through the I/P dimming lamps control circuit. The setting of the I/P dimmer switch determines the amount of voltage that the I/P dimmer switch supplies to the BCM through the I/P dimming lamps low reference circuit. The BCM then sends a pulse width modulation (PWM) voltage to all the interior lamps. All the VF and incandescent back lighting lamps are provided a specific voltage and are then grounded. When the headlight switch is turned to the park lamp or headlamp position, all incandescent back lighting turn ON at the dimming level indicated by the I/P dimmer switch. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.


Do you know what DTC'S - diagnostic trouble codes are ? Codes set in the BCM
DTC B2610 00: Passenger Compartment Dimming 1 Circuit
DTC B2615 00: Passenger Compartment Dimming 2 Circuit
DTC B2652 00: Passenger Compartment Dimming 3
Circuit/System Description
The instrument panel (I/P) lamp dimmer switch is used to increase and decrease the brightness of the interior backlighting components. The I/P 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 I/P dimmer switch. When the I/P dimmer switch is placed in the desired position, the dimmed voltage setting is applied from the I/P dimmer switch through the I/P dimmer switch signal circuit to the BCM. The BCM interprets the signal and applies the dimmed voltage to the I/P lamps supply voltage circuit and the interior backlighting components dim to the requested level. Ground for the I/P dimmer switch is provided at G201.

sunroof fuse 1 20amp / power windows - circuit breaker 25 amp
both of these are located in the instrument panel fuse box .

Hello
The backlight can be adjusted as follows:

This alarm clock radio features an adjustable display backlight, with dim, medium, and bright settings. To

select a backlight setting, press the 3 Snooze/Dimmer Bar until the desired brightness is reached.
Please note that the backlight will not work while the clock is operating on battery power.
OK

The clock motor has gone bad.
There are no replacement clock motors.
To work around, buy cheap plug-in timer, set power pack to override and plug power pack into cheap timer.
Power packs have 5 year limited warranty.

Hi.

This is a common problem with this model.

The LCD has a dimmer circuit that can be responsible, in some case it is not the dimmer regulation, but the LCD control circuit itself. In that case you have no LCD backlight and the display is almost unreadable. If that is the problem, changing dimmer settings with procedure below will not help.

Most of the time the problem is dimmer regulation.

About dimmer regulation:

Try disconnecting the unit power cord for ten minutes and connect back.
Try holding down CD or CLOCK button and pressing at the same time the volume buttons. This procedures regulates Bose dimmers setting in a scale from one to 9. The dimmer has separate settings for medium and low brightness. Set both to 5 if you want to disable dimmer settings.

See instructions below:

Initial Settings
Adjusting initial settings
Using the initial settings, you can customize
various system settings to achieve optimal performance
from this unit.

1 Press SOURCE and hold until the unit
turns off.
2 Press FUNCTION and hold until function
name appears in the display.
3 Press FUNCTION repeatedly to switch
between the following settings:
CALENDAR (date and clock)—
WARNING TONE (warning tone)—AUX1 (auxiliary
input1)—AUX2 (auxiliary input2)—
DIMMER (dimmer)—S/W CONTROL (rear
output and subwoofer controller)—
DEMONSTRATION (feature demo)—
EVER-SCROLL (ever scroll)
Use the following instructions to operate each
particular setting.
# To cancel initial settings, press BAND.
# You can also cancel initial settings by holding
down FUNCTION until the unit turns off.

Setting the date and clock
Use these instructions to set the clock.
1 Press FUNCTION to select clock.
2 Press c or d to select the segment you
wish to set.
Day—Month—Year—Hour—Minute
As you select segments of the clock display
the segment selected will blink.

3 Press a or b to set the date and clock.
Pressing a will increase the value of the selected
segment. Pressing b will decrease the
value of the selected segment.

Check the dimmer switch to your dash light. If there turned down, your dash and radio illumination light will be dime or not working at all. Keep me posted, be glad to know if it is the dimmer switch turned down or you dimmer switch has gone bad. Good luck

try turning switch up when testing

The display on my clock is red as well. I found it that way when I came home from work today. It had lost all of its settings as well. I put everything back to the way it was supposed to be but I can't get the color to change. I guess something just quit.
