BSW SYSTEM OPERATION DESCRIPTION
- BSW control module enables BSW system.
- The BSW control module turns on the BSW system when the warning systems switch is turned ON.
- Side radar detects a vehicle in the adjacent lane, and transmits the vehicle detection signal to BSW control module via BSW communication.
- BSW control module starts the control as follows, based on a vehicle detection signal, turn signal and dimmer signal transmitted from BCM via CAN communication: Buzzer output signal transmission to combination meter via CAN communication. BSW indicator signal and BSW indicator dimmer signal transmission to side radar via BSW communication.
- Side radar transmits an indicator operation signal to the BSW indicator according to BSW indicator signal and BSW indicator dimmer signal.
Operation Condition of BSW System
BSW control module performs the control when the following conditions are satisfied.
- When the warning systems switch in turned ON.
- When the vehicle drives at approximately 32 km/h (20 MPH) or more to the forward direction.
Note. After the operating conditions of warning are satisfied, the warning continues until the vehicle speed reaches approximately 29 km/h (18 MPH) The BSW system may not function properly, depending on the situation. Refer to " PRECAUTIONS FOR BLIND SPOT WARNING ".
DISPLAY AND WARNING OPERATION
Vehicle condition/Driver's operation Action Warning systems ON indicator Vehicle speed (Approx.) [km/h (MPH)] Turn signal condition Status of vehicle detection within detection area Indication on the BSW indicator Buzzer OFF - - - OFF OFF ON Less than approx. 29 (18) - - OFF OFF Approx. 32 (20) or more - Vehicle is absent OFF OFF OFF Vehicle is detected ON OFF ON (vehicle detected direction) Before turn signal operates Vehicle is detected Blink Short continuous beep Vehicle is detected after turn signal operates Blink OFF
