Power Operated Outside Rear View Mirror System

WARNING: This page is about a different car, the 2021 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

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 armrest 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:

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 .
Power Mirror Switch - Vehicles equipped with the power operated outside rear view mirror system have a power mirror selector switch, a power mirror control switch, and a power folding mirror switch integral to the power switch module located near the front of the armrest on the driver side front door interior trim panel. Refer to SWITCH, LOCK, DESCRIPTION .

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

Blind Spot Sensors - Vehicles equipped with the Blind Spot Monitoring (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 ECU. Each of the two ECUs are independent and communicates on the CAN data bus and is hardwired to its respective RBSS or LBSS. 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.
Body Control Module (BCM) - 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 (BCM), DESCRIPTION .
Radio Frequency Hub (RF-Hub) - The RF-Hub is the Remote Keyless Entry (RKE) system controller and the RF signal receiver. Refer to MODULE, RADIO FREQUENCY (RF HUB), DESCRIPTION .

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

Blind Spot Monitor Display - In vehicles also equipped with the optional 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 RBSS or RBSS detects an object of interest in one of the monitored vehicle blind spots. Refer to DISPLAY, BLIND SPOT, DESCRIPTION .
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 .
