Blind Spot Module - Operation

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.
