Principles of Operation

Power Sunshade

The power sunshade system consists of the following:

- Sunshade switch

- Sunshade module

- Sunshade motor

- Sunshade assembly

Pressing the sunshade switch (a single position, momentary contact, located next to the selector lever) sends a ground signal to the sunshade module. The sunshade module performs an auto up/auto down operation, depending on the current position of the sunshade. An auto up or auto down operation can be interrupted at any time by pressing the sunshade switch again. Pressing the sunshade switch again will cause the sunshade module to reverse the direction of the sunshade.

If the sunshade module senses the motor current draw has gone beyond 2.5A (obstruction), the sunshade module will remove power to the motor and the sunshade will stop.

When the selector lever is placed into the REVERSE position, the sunshade module receives a voltage signal from the backup lamp relay and the sunshade is lowered.
