Blind Spot Module: Description and Operation

Blind Spot Module

Description






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.

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.

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.

Operation

The microprocessor based Blind Spot Monitor (BSM) module is the central component of the BSM system. It receives and analyzes data from the sensors, calculates and communicates the proper information to the Driver/Passenger door module to illuminate the display, performs system diagnostics, and communicates with other electronic modules in the vehicle or with a diagnostic scan tool over the Controller Area Network (CAN) data bus. The module operates on battery voltage received through a fuse in the Totally Integrated Power Module (TIPM), and is grounded through a take out and eyelet terminal of the body wire harness that is secured by a screw to the body sheet metal. For more information on the operation of the BSM module and other components in the BSM system, refer to => [ Blind Spot Monitor (BSM) System ] Blind Spot Monitor (BSM) System.
