Audible Warning Device: Description and Operation
Chime/Buzzer - Description
Blind Spot Module
DESCRIPTION
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. The BSM system can also be manually enabled or disabled on vehicles equipped with the Compass Mini
Trip Computer option.
-
Blind Spot Display (3) - 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 (2) - Vehicles equipped with the blind spot monitor system include a module which is secured to a mounting bracket by two
fasteners and mounted to the right quarter inner panel where it is concealed beneath the quarter panel inner trim.
-
Blind Spot Sensors (1) - 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 directly below the left and right tail lamps.
Hardwired circuitry connects the various blind spot monitor system components to each other through the electrical system of the vehicle. These
hardwired 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.
