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).

DIAGNOSIS SYSTEM (LANE CAMERA 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.

AUTO AIM

Outputs camera unit, calculates dislocation of the camera, and displays adjustment direction. 
Refer to 

CCS-112, "CAMERA AIMING ADJUSTMENT : Description"

.
