Blind Spot Monitor System: Operation

Blind Spot Monitoring (BSM) system operation: 

• When the vehicle speed exceeds 10 km/h (6 mph) and the right or left blind spot sensor detects an object within 50 km/h (30 mph) of vehicle speed in the monitored zone, the sensor will then request a blind spot icon illumination over CAN-IHS to the appropriate mirror. A yellow LED triangle will then illuminate in the upper corner of the appropriate mirror.
• If the driver attempts to enter the zone, where the object has been detected with the turn signal activated, the sensor will send out two additional requests over CAN-IHS:
  • The audio speakers will mute
  • A chime will sound

The Rear Cross-Path Detection system: 

• Monitors the rear detection zones for vehicles that are moving toward the sides of the vehicle with a minimum speed of 3 Km/h (2 mph):
  • The LED icons on the outside mirrors will illuminate on the side of the vehicle that is approaching
  • Is activated when the shifter is in reverse
• Functions using the blind spot sensors as cross-path monitors.
• Is always included with the Blind Spot Monitor system.

The Blind Spot Sensors: 

• Two Box System: Left Blind Spot Sensor (LBSS) and the Right Blind Spot Sensor (RBSS) are two independent control units
• No Blind Spot ECU
• Each sensor communicates over CAN-IHS to its respective side mirror to illuminate the LED icon
• No private CAN Bus between sensors
• Each sensor sets its own diagnostic faults
• Sensors are configured (default) with LED
• The Blind Spot sensors are mounted to the inside of the rear fascia
