to combination meter terminal 9

through seat belt buckle switch (driver side) terminal 60.
Seat belt buckle switch (driver side) terminal 61A is grounded through body grounds B15 and B45.
Combination meter sends seat belt unfastened [seat belt buckle switch (driver side) ON] signal to unified
meter and A/C amp. with communication line between unified meter and A/C amp. and combination meter.
BCM receives seat belt unfastened [seat belt buckle switch (driver side) ON] signal from unified meter and A/
C amp. with CAN communication line, and sends seat belt warning signal to unified meter and A/C amp. with
CAN communication line. Unified meter and A/C amp. sends seat belt warning signal to combination meter
with communication line between unified meter and A/C amp. and combination meter.
When combination meter receives seat belt warning signal, it sounds warning chime.
CAN Communication System DescriptionAKS007Z2
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
CAN Communication UnitAKS007YY
Refer to LAN-30, "CAN Communication Unit" in “LAN SYSTEM”.

SKIB1784E
Component Description
LDW camera unit Detects the lane marker by the built-in camera, gives judgement for the warning according to the
result of detection and signals from each unit, and transmits the operation signal to LDW chime and
LDW indicator lamp.
LDW switch

Selects ON/OFF of the system.

Indicates ON/OFF of the signal with LDW system ON indicator.
LDW chime Gives a warning chime according to the direction from LDW camera unit.
LDW indicator lamp Installed in combination meter, and indicates the system condition.

Blinks when LDW system is functioning to alert the driver.

Stays on when LDW system is malfunctioning.*
BCM Transmits turn indicator signal to LDW camera unit with CAN communication signal.
ABS actuator and electric unit
(control unit) Transmits vehicle speed signal to LDW camera unit with CAN communication signal.
TCM Transmits vehicle speed signal to LDW camera unit with CAN communication signal. (For detecting
incorrect speed.)
