Component
Description
Lane camera unit
• Detects the lane marker by the built-in camera.
• Judges the lane departure depending on the lane detection result and each signal.
• Transmits the detected lane conditions to ABS actuator and electric unit (control unit) via CAN com-
munication.
• Controls the lane departure warning buzzer, lane departure warning lamp, LDW ON indicator and
LDP ON indicator lamp.
ABS actuator and electric unit
(control unit)
• Transmits vehicle speed signal to lane camera unit via CAN communication.
• Judges necessary yaw moment depending on each signal.
• Controls the brake pressure of each wheel individually to generate the intended movement.
Lane departure warning buzz-
er
Gives a warning according to the direction from lane camera unit.
LDP ON switch
(On the ICC steering switch)
Inputs the switch signal to ECM.
Combination meter
Turns the lane departure warning lamp and LDP ON indicator lamp ON/OFF according to the signals
from the lane camera unit via CAN communication (through unified meter and A/C amp.).
LDP ON indicator lamp
(Green)
Indicates LDP system status.
Lane departure warning lamp
(Yellow)
• Blinks when LDP is functioning to alert the driver.
• Stays ON when LDW/LDP system is malfunctioning.
BCM
• Transmits turn indicator signal to lane camera unit via CAN communication.
• Transmits vehicle conditions to ABS actuator and electric unit (control unit) via CAN communica-
tion.
ECM
Transmits vehicle conditions and ICC steering switch signal (LDP ON switch signal) to ABS actuator
and electric unit (control unit) via CAN communication.
Unified meter and A/C amp.
Transmits ambient temperature signal to lane camera unit via CAN communication.
Steering angle sensor
Transmits steering angle sensor signal to ABS actuator and electric unit (control unit) via CAN com-
munication.
TCM
Transmits vehicle conditions to ABS actuator and electric unit (control unit) via CAN communication.
ICC sensor integrated unit
Transmits ICC system conditions to ABS actuator and electric unit (control unit) via CAN communica-
tion.
Yaw rate/side G sensor
Inputs detected yaw rate signal to ABS actuator and electric unit (control unit).

CONSULT-III Function (LANE CAMERA)
INFOID:0000000003514576
DESCRIPTION
CONSULT-III performs the following functions by communicating with the lane camera unit.
WORK SUPPORT
Cause of Auto-Cancel Display Item List
When LDP control is canceled under the operating condition, “CAUSE OF AUTO-CANCEL” is memorized.
• Last five cancel (system cancel) causes are displayed.
• “CAUSE OF AUTO-CANCEL” displays the number of times of ignition switch ON/OFF up to a maximum of
“39”. “39” is kept even when the number exceeds “39”. The number returns to 0 when detecting the same
cancellation causes are detected.
Select diag mode
Function
Work support
• Performs the camera aiming.
• Displays causes of automatic cancellation of the LDP function.
Self Diagnostic Result
Displays memorized DTC in the lane camera unit.
Data Monitor
Displays real-time data of lane camera unit.
Active Test
Enables operation check of electrical loads by sending driving signal to them.
Ecu Identification
Displays part number of lane camera unit.
Work support item
Function
CAUSE OF AUTO-CANCEL
Indicates causes of automatic cancellation of the LDP.
