Commander 4WD V8-4.7L VIN N (2006)
momentary lane change position in each direction that provides turn signals only until the control stalk is released. When the control stalk is
moved to a detent turn signal switch position, a cancel actuator extends toward the center of the steering column. A turn signal cancel cam that is
integral to the clockspring/SCM rotates with the steering wheel and the cam lobes contact the cancel actuator when it is extended from the left
multi-function switch. When the steering wheel is rotated during a turning maneuver, one of the two turn signal cancel cam lobes will contact the
turn signal cancel actuator. The cancel actuator latches against the cancel cam rotation in the direction opposite that which is signaled. If the left
turn signal detent is selected, the lobes of the cancel cam will ratchet past the cancel actuator when the steering wheel is rotated to the left, but will
unlatch the cancel actuator as the steering wheel rotates to the right and returns to center, which will cancel the turn signal event and release the
control stalk from the detent so it returns to the neutral Off position. The SCM reads the resistor multiplexed input from the left multi-function
switch and sends an electronic switch status message over the CAN data bus to the other electronic modules in the vehicle.
INTERIOR LIGHTING
Following are descriptions of the how the left multi-function switch is operated to control the many interior lighting functions and features it provides:
-
Interior Lamps Defeat - The interior lamps defeat feature is requested when the left multi-function switch control sleeve is rotated to the interior
lamps defeat detent position. The SCM reads the resistor multiplexed input from the left multi-function switch and sends an electronic switch
status message over the CAN data bus to the other electronic modules in the vehicle.
-
Interior Lamps On - The interior lamps on feature is requested when the left multi-function switch control sleeve is rotated to the interior lamps
On detent position. The SCM reads the resistor multiplexed input from the left multi-function switch and sends an electronic switch status message
over the CAN data bus to the other electronic modules in the vehicle.
-
Panel Lamps Dimming - The panel lamps dimming function is active only when the left multi-function switch control knob is in any exterior
lighting On position. With the exterior lighting On, the panel lamps dimming level is requested when the left multi-function switch control sleeve
is rotated to any one of six minor detent positions. The SCM reads the resistor multiplexed input from the left multi-function switch and sends an
electronic switch status message over the CAN data bus to the other electronic modules in the vehicle.
-
Parade Mode - The parade or funeral mode is active only when the left multi-function switch control knob is in any exterior lighting On position.
With the exterior lighting On, the parade mode is requested when the left multi-function switch control sleeve is rotated to the parade mode detent
position. The SCM reads the resistor multiplexed input from the left multi-function switch and sends an electronic switch status message over the
CAN data bus to the other electronic modules in the vehicle.
