Blind Spot Monitor System

WARNING: This page is about a different car, the 2012 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.

The Blind Spot Monitor (BSM) system is an optional factory-installed electronic driving aid. During driving maneuvers the system alerts the vehicle operator to vehicles located in the alert zones immediately behind and to the left or right of the vehicle which, due to the surrounding rear vehicle structure, might be otherwise difficult to perceive. When an object is detected, the system uses an electromechanical transducer within the cluster and Light Emitting Diode (LED) indicators within the side view mirrors to provide the vehicle operator with visual and audible indications of the presence of other vehicles.

The BSM system includes the following major components, which are described in further detail elsewhere in this service information:

Electronic Vehicle Information Center - In vehicles equipped with the optional blind spot monitor system, the optional Electronic Vehicle Information Center (EVIC) in the instrument cluster displays textual warnings and error messages and emits audible warnings related to the current operating status of the BSM system and provides an interface that allows the vehicle operator to manually disable or enable the system using the customer programmable features option.
Blind Spot Display - Vehicles equipped with the blind spot monitor system have an LED display unit mounted in the side view mirrors. The body of the displays are concealed to the back side of the side view mirrors. Only the amber colored triangle is visible on the outer surface of the mirror glass.
Blind Spot Module - Vehicles equipped with the blind spot monitor system include a module which is secured to the right quarter inner panel by two retainers and concealed behind the interior trim panel.
Blind Spot Sensors - Vehicles equipped with the blind spot system have two radar blind spot sensors that are concealed behind the rear bumper fascia. Each sensor is snapped into an individual molded plastic mounting bracket secured at horizontal intervals located on the back side of the rear bumper fascia near the left and right wheel openings.

Hard-wired circuitry connects the various blind spot monitor system components to each other through 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 and to the vehicle electrical system 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 blind spot monitor system components cannot be adjusted or repaired. If any of the BSM system components are damaged or inoperative, that component must be replaced.
