signal and transmits BSW indicator signal and BSW indicator dimmer signal to side radar
Activates the warning buzzer and warning systems ON indicator
Side radar LH/ RH Being connected with ADAS control unit via ITS communication, transmits vehicle detection sig-
nal
Receives BSW indicator signal and BSW indicator dimmer signal from ADAS control unit and transmits an indicator operation signal to BSW indicator LH/RH
RH side radar equips right/left switching signal circuit for identifying LH or RH because the parts
of side radar are common for right and left
BSW indicator LH/ RH Receives BSW indicator operation signal from side radar LH/RH and turns OFF, turns ON or blinks
ABS actuator and electric unit
(control unit) Transmits vehicle speed signal to ADAS control unit via CAN communication
Warning systems switch Inputs the switch signal to ADAS control unit
Warning systems ON indicator
(On the warning systems switch) Indicates BSW system status
Warning buzzer Receives buzzer signal from ADAS control unit and sounds buzzer.
Combination meter Receives BSW warning lamp signal via CAN communication
Turns the BSW warning lamp ON/OFF according to the signals from the ADAS control unit via
CAN communication
BCM Transmits turn indicator signal to ADAS control unit via CAN communication
Transmits dimmer signal to ADAS control unit via CAN communication
TCM Transmits the shift position signal to ADAS control unit via CAN communication
