Inside Rearview Mirror W/ the Automatic Day-Night Feature SYS Operation

With the ignition switch in the ON position, ignition 1 voltage is supplied through the IGN 1 fuse to the inside rearview mirror. The inside rearview mirror uses 2 photocell sensors in order to determine light conditions in the front and the back of the vehicle. At night, with automatic day-night feature enable, the mirror automatically darkens to reduce the glare from the headlamps from behind. In the daytime, the mirror is in a normal state. With the gear selector lever in the REVERSE position, backup lamp supply voltage is supplied as an input to the inside rearview mirror. The automatic day-night mirror will gradually change to a normal state as a result of the backup lamp supply voltage input. Ground for the inside rearview mirror is provided by G203.
