Cirrus V6-2.5L SOHC 24 Valve (1996)
Dimmer Switch: Description and Operation
Dimmer Control
The dimmer control is used to control the intensity of the instrument panel lamps. It is located in the left multi-function switch. Power for the control is
supplied from the L7 circuit, which is the feed for the parking lamps. This circuit is HOT when the parking lamp switch is in the ON position. Ground
for the control is provided on the Z1 circuit which terminates at the instrument panel left side cowl.
The control uses a variable resistor and is connected to circuit E19. Circuit E19 connects to the Body Control Module (BCM). When the operator moves
the control, resistance in the circuit changes and the signal sent to the BCM changes. With the change is resistance the BCM sends a signal over CCD
Bus to the instrument panel lamps changing the lamps intensity.
