Description And Operation: Interior
The automatic dimming inside rear view mirror is able to automatically change its reflectance. The automatic dimming inside rear view mirror system is a completely self-contained unit that replaces the standard equipment manual prismatic inside rear view mirror. The two layers of conductive mirror glass with a thin layer of electrochromic material between them, two photocell light sensors (2) in the front, one photocell light sensor in the back,, the mirror connector receptacle and the electronic mirror control circuitry are all self-contained within the inside rear view mirror housing. The electronics integrated within this mirror also control the dimming of the exterior mirrors.
The automatic dimming mirror is secured to the same mounting button on the inside of the windshield glass and in the same manner that is used to mount the standard equipment manual prismatic mirrors. The mirror is connected to the vehicle electrical system through a dedicated take out and connector of the overhead wire harness. The automatic dimming inside rear view mirror receives battery current through a fused ignition switch output (run-start) circuit and a fuse in the Power Distribution Center (PDC) so the mirror will only operate when the ignition switch is in the ON or START positions.
The automatic dimming inside rear view mirror sensitivity cannot be repaired or adjusted. If any component of this unit is ineffective or damaged, the entire inside rear view mirror unit must be replaced. For service procedures. Refer to MIRROR, REARVIEW, REMOVAL AND INSTALLATION .
