AUTOMATIC DIMMING INSIDE REAR VIEW MIRROR SYSTEM

The automatic dimming inside rear view mirror is available factory-installed equipment on this vehicle. This mirror is also known as the ElectroChromic Mirror Module (ECMM). This mirror system uses an ElectroChromic (EC) material and will automatically adjust the reflectance of the mirror glass to reduce glare from the headlamps of following vehicles during dark or night time driving conditions. Reducing glare will improve driver comfort and vision under these driving conditions. The components of the automatic dimming inside rear view mirror system are completely self-contained within the inside rear view mirror. Refer to MIRROR, AUTOMATIC DAY AND NIGHT, DESCRIPTION .

Certain functions and features of the EC mirror system may rely upon resources shared by other electronic modules in the vehicle over a Local Interface Network (LIN) data bus as well as over the Controller Area Network (CAN) data bus. Other electronic modules in the vehicle that may affect EC mirror operation are

1. Body Control Module - The Body Control Module (BCM) is located beneath the instrument panel on the driver side of the vehicle. The BCM controls many of the body electrical system components. The BCM is both a LIN master node and a gateway to the CAN data bus. Refer to «MODULE, BODY CONTROL, DESCRIPTION»(ref-646224-S31141207742014072800000) .
2. Powertrain Control Module - The Powertrain Control Module (PCM) (also known as the Engine Control Module/ECM) is located beneath the hood in the engine compartment of the vehicle. The PCM controls many of the powertrain electrical system components. The PCM communicates on the CAN data bus. Refer to «MODULE, POWERTRAIN CONTROL, DESCRIPTION»(ref-646224-S10719748682014072800000) .
3. Transmission Control Module - On vehicles with an automatic transmission, the Transmission Control Module (TCM) (also known as the Engine Control Module/ECM) is located beneath the hood in the engine compartment of the vehicle. The TCM controls many of the automatic transmission electrical system components. The TCM communicates on the CAN data bus. Refer to «MODULE, TRANSMISSION CONTROL, OPERATION»(ref-646224-S13893537542014072800000) .

These components and their controls are combined to provide the following EC mirror system feature

1. Dimming Disabled In Reverse - The automatic dimming feature of the EC mirrors is disabled anytime the Reverse position of the transmission is selected.

POWER OPERATED OUTSIDE REAR VIEW MIRROR SYSTEM

The power operated outside rear view mirror system is available factory-installed equipment on this vehicle. This system allows the driver to adjust both the driver and passenger side outside rear view mirrors electrically from the driver seat by operating switches on the arm rest of the driver side front door inside trim panel. These switches allow the vehicle operator a convenient means of adjusting the mirrors to optimize peripheral vision to include the areas at the sides and rear corners of the vehicle, those blind spot areas that are generally blocked from the view of the vehicle operator by the vehicle structure.

The power operated outside rear view mirror system includes the following major components, which are described in further detail elsewhere in this service information

1. Power Mirror - Vehicles equipped with the power operated outside rear mirror system have a power operated mirror secured to the mirror flag area at the front of each front door glass opening. Refer to «MIRROR, OUTSIDE REARVIEW, DESCRIPTION»(ref-646267-S15454171132014072800000) .
2. Power Mirror Switch - Vehicles equipped with the power operated outside rear view mirror system have a power mirror selector switch and a power mirror control switch integral to the power switch module located near the front of the arm rest on the driver side front door interior trim panel. Refer to «SWITCH, LOCK, DESCRIPTION»(ref-646254-S21612093202014072800000) .

Certain functions and features of the power operated outside rear view mirror system may rely upon resources shared by other electronic modules in the vehicle over a Local Interface Network (LIN) data bus as well as over the Controller Area Network (CAN) data bus. Other electronic modules in the vehicle that may affect power operated outside rear view mirror operation are

1. Blind Spot Sensors - Vehicles equipped with the BSM system have both a Left Blind Spot Sensor (LBSS) and a Right Blind Spot Sensor (RBSS). The LBSS and the RBSS each include a RAdio Detection And Ranging (RADAR) sensor and an integral electronic control unit. Each of the two control units is independent, communicates on the Controller Area Network (CAN) data bus and is hard wired to its respective right or left blind spot display. The LBSS and the RBSS are concealed behind their respective right and left outboard ends of the rear bumper fascia, just behind the rear wheel openings.
2. Body Control Module - The Body Control Module (BCM) is located beneath the instrument panel on the driver side of the vehicle. The BCM controls many of the body electrical system components. The BCM is both a LIN master node and a gateway to the CAN data bus. Refer to «MODULE, BODY CONTROL, DESCRIPTION»(ref-646224-S31141207742014072800000) .
3. Radio Frequency Hub Module - The Radio Frequency Hub Module (RFHM) (also known as the RF Hub) is the RKE system control module and RF receiver located beneath the shelf support behind the rear seat back and is concealed beneath the package tray interior trim. Refer to «MODULE, RADIO FREQUENCY (RF HUB), DESCRIPTION»(ref-646224-S30712734272014072800000) .

These components and their controls are combined to provide the following power operated outside rear view mirror system features

1. Blind Spot Monitor Display - In vehicles also equipped with the optional Blind Spot Monitor (BSM) system, an amber Light Emitting Diode (LED) unit behind a small, triangular translucent icon in each outside rear view mirror glass is illuminated each time the right or left blind spot sensor detects an object of interest in one of the monitored vehicle blind spots. Refer to «DISPLAY, BLIND SPOT, DESCRIPTION»(ref-646242-S13010147562014072800000) .
2. Heated Mirrors - The heated mirror option includes an electric heating grid behind the mirror glass in each outside rear view mirror, which can clear the mirror glass of ice, snow, or fog. Refer to «DESCRIPTION»(ref-646261-S20390113972014072800000) .
3. Puddle Lamps - In vehicles equipped with this option, white Light Emitting Diode (LED) units behind a small round lens on the underside of each outside rear view mirror illuminate the ground outside each front door when a door is opened. Refer to «DESCRIPTION»(ref-646229-S10646997182014072800000) .
4. Signal Lamps - In vehicles equipped with this option, two amber Light Emitting Diode (LED) units illuminate a light pipe behind a clear lens that wraps around the lower outward and forward-facing surfaces of each mirror shell in concert with the turn signals. Refer to «DESCRIPTION»(ref-646229-S10646997182014072800000) .

The ElectroChromic Mirror Module (ECMM) of the automatic dimming inside rear view mirror system receives battery current on a fused ignition output (run) circuit from a fuse in the Junction Block (JB) (also known as the interior Power Distribution Center/PDC). The ECCM has a path to ground at all times through a take out and eyelet terminal of the body wire harness that is secured to the body sheet metal. These connections allow the automatic dimming inside rear view mirror system to operate whenever the status of the ignition switch is ON. A switch located on the front of the inside rear view mirror housing allows the vehicle operator to select whether the automatic dimming mirror system is operational. When the automatic dimming mirror system is turned ON, a green power indicator within the mirror housing is illuminated by an integral Light-Emitting Diode (LED) unit.

The power operated outside rear view mirror system receives battery current at all times on a non-switched fused B(+) circuit through a fused B(+) fuse located in the underhood Power Distribution Center (PDC). The power mirror system has a path to ground at all times through a take out and eyelet terminal of the body wire harness that is secured to the body sheet metal. These connections allow the power mirror system to remain operational, regardless of the status of the ignition switch. However, a neutral position of the power mirror selector switch will prevent inadvertent power operated outside rear view mirror system operation.
