BSW SYSTEM OPERATION DESCRIPTION
- BSW control module enables BSW system.
- The BSW control module turns on the BSW system when the BSW 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 BSW 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 BSW 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
Scheme 1
Scheme 2
Note. If vehicle speed exceeds approximately 32 km/h (20MPH), BSW function operates until the vehicle speed becomes lower than approximately 29km/h (18MPH). Time shown in the figure is approximate time.
DESCRIPTION
CONSULT performs the following functions by communicating with the side radar LH.
| Select diag mode | Function |
|---|---|
| Self Diagnostic Result | Displays memorized DTC in the side radar |
| Data Monitor | Displays real-time data of side radar |
| Active Test | Enables operation check of electrical loads by sending driving signal to them |
| Ecu Identification | Displays part number of side radar |
CONSULT performs the following functions by communicating with the side radar RH.
| Select diag mode | Function |
|---|---|
| Self Diagnostic Result | Displays memorized DTC in the side radar |
| Data Monitor | Displays real-time data of side radar |
| Active Test | Enables operation check of electrical loads by sending driving signal to them |
| Ecu Identification | Displays part number of side radar |
Always perform the BSW system action test to check that the system operates normally after replacing the side radar LH/RH, or repairing any BSW system malfunction.
| WARNING | Be careful of traffic conditions and safety around the vehicle when performing road test. |
| CAUTION | Fully understand the following items well before the road test; Precautions: Refer to " PRECAUTION FOR BSW SYSTEM SERVICE ". System description: Refer to " SYSTEM DESCRIPTION ". Normal operating condition: Refer to " DESCRIPTION ". |
