Automatic Day/Night Mirror - Description

DESCRIPTION

An automatic dimming inside rear view mirror is an available factory-installed option on this vehicle. This mirror features a thin layer of ElectroChromic (EC) material sandwiched between two pieces of conductive glass to make up the face of the mirror. The EC material explains how this mirror also became known as the ElectroChromic Mirror Module (ECMM). The ECMM will automatically change the reflectance of the inside rear view mirror glass to reduce the glare of headlamps approaching the vehicle from the rear while driving during dark or night time conditions.

The ECMM is a completely self-contained unit that replaces the standard equipment prismatic inside rear view mirror. Besides the mirror glass, the ECMM includes a power switch, a Light Emitting Diode (LED) power indicator, two photocell sensors, the electronic mirror control circuitry and the hardware necessary to communicate as a Local Interface Network (LIN) slave node on the LIN data bus.

The ECMM may also integrate these other optional features:

- Imager Camera - For vehicles equipped with the SmartBeam(R) Automatic Headlamp High Beam System, a digital imaging camera is integral to the ECMM mounting bracket and shares the LIN data bus communication features of the ECMM.

- Telematics Microphones - For vehicles equipped with the optional Uconnect(TM) Hands-Free Communication System, two hard wired telematics microphones are integral to the upper surface of the ECMM housing.

Hard wired circuitry connects the ECMM to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the ECMM through the use of a combination of soldered splices, splice block connectors and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention as well as pin-out and location views for the various wire harness connectors, splices and grounds.

The ECMM cannot be repaired or adjusted. If any component of this unit is ineffective or damaged, the entire ECMM unit must be replaced.

OUTSIDE MIRROR -The automatic dimming driver side outside rear view mirror is able to automatically change its reflectance. The automatic dimming outside rear view mirror replaces the standard equipment outside rear view mirror. The two layers of conductive mirror glass with a thin layer of electrochromic material between them is contained within the outside rear view mirror glass case. However, this mirror relies upon the photocells and mirror control circuitry of the automatic dimming inside rear view mirror to control its reflectance.

The automatic dimming outside rear view mirror is secured to the same mounting flag on the front door panel and in the same manner that is used to mount the standard equipment outside rear view mirrors. The mirror is connected to the vehicle electrical system through a dedicated take out and connector of the front door wire harness. The automatic dimming circuitry of the outside rear view mirror receives current through auto day/night mirror feed (+) and return (-) circuits from the inside rear view mirror, and will only operate when the ignition switch is in the ON or START positions.

The automatic dimming outside rear view mirror sensitivity cannot be repaired or adjusted. If any component of this unit is ineffective or damaged, the entire outside rear view mirror unit must be replaced.
