ceived from the ABS actuator and electric unit (control unit) via CAN communication
and the parking brake switch signal from the parking brake switch and sounds the
warning buzzer.
• Receives the vehicle speed signal from the ABS actuator and electric unit (control unit)
and the seat belt buckle switch signal (driver side) from the seat belt buckle switch (driv-
er side) and transmits them to BCM via CAN communication.
BCM
