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.
