POWER SUPPLY AND GROUND CIRCUIT
With the ignition switch in the ON or START position, power is supplied
 through 10A fuse [No. 12, located in the fuse block (J/B)]
 to LDW camera unit terminal 1.
Ground is supplied
 to LDW camera unit terminals 6 and 12
 through grounds M45, M85 and M35.
Action TestINFOID:0000000001328494
LDW SYSTEM RUNNING TEST
WARNING:
 Be careful when performing road test.
 Understand “Precautions” and “System Description” well before the road test. Refer to DI-69, "
Pre-
caution for Lane Departure Warning (LDW) system" and DI-69, "System Description".
Function Check
Check the LDW system operation according to the c ondition that the warning function works. Refer to DI-69,
"System Description".
Camera Aiming AdjustmentINFOID:0000000001328495
OUTLINE
Adjust the camera aiming every time the LDW camera unit is removed or installed.
CAUTION:
 Place the vehicle on the level ground when the camera aiming adjustment is operated.
 Follow the CONSULT-III when ad justing the camera aiming. (Camera aiming adjustment cannot be
operated without CONSULT-III.)
PREPARATION
 Keep all tires inflated to correct pressures. Adjust the tire pressure to the specified pressure value.
 There is no-load in vehicle. Check if coolant, engine oil are filled up to correct level and fuel tank is full.
 Shift the gear into “P” position and release the parking brake.
 Clean the windshield.
NOTE:
Do not place anything reflective on t he upper surface of instrument panel.
TARGET SETTING
Preparation Aiming Adjustment Jig
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.)

PRECAUTIONS
Precaution
INFOID:0000000001325892
 Always use a 12 volt battery as power source.
 Do not attempt to disconnect battery cables while engine is
running.
 Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
 Before removing parts, turn ig nition switch OFF and then dis-
connect negative battery cable.
 Do not disassemble ECM.
 If a battery cable is disconnected, the memory will return to
the ECM value.
The ECM will now start to self-c ontrol at its initial value.
Engine operation can vary slight ly when the terminal is dis-
connected. However, this is no t an indication of a malfunc-
tion. Do not replace parts b ecause of a slight variation.
 If the battery is disconnected, the following emission-related
diagnostic information will be lost within 24 hours.
- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
 When connecting ECM harness co nnector, fasten it securely
with a lever as far as it will go as shown in the figure.
 When connecting or disconnect ing pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
 Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and co ndenser, thus resulting in dam-
age to ICs.
 Keep engine control system harn ess at least 10 cm (4 in) away
from adjacent harness, to preven t engine control system mal-
functions due to receiving exter nal noise, degraded operation
of ICs, etc.
 Keep engine control system parts and harness dry.
