LDW SYSTEM RUNNING TEST
WARNING:

Be careful when performing road test.

Understand “Precautions” and “System Description” well before the road test. Refer to DI-80,
"Precautions for Lane Departure Warning (LDW) system" and DI-80, "System Description" .
Function Check
Check the LDW system operation according to the condition that the warning function works. Refer to DI-80,
"LDW SYSTEM OPERATION" .
Camera Aiming AdjustmentNKS00315
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-II when adjusting the camera aiming. (Camera aiming adjustment cannot be
operated without CONSULT-II.)
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 the upper surface of instrument panel.
TARGET SETTING
Preparation Aiming Adjustment Jig
For aiming adjustment, prepare the following jigs and targets.

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45

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-control at its initial value.
Engine operation can vary slightly when the terminal is dis-
connected. However, this is not an indication of a malfunc-
tion. Do not replace parts because 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 connector, fasten it
securely with a lever as far as it will go as shown in the fig-
ure.

When connecting or disconnecting 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)
voltage to develop in coil and condenser, thus resulting in
damage to ICs.

Keep engine control system harness at least 10 cm (4 in)
away from adjacent harness, to prevent engine control sys-
tem malfunctions due to receiving external noise, degraded
operation of ICs, etc.

Keep engine control system parts and harness dry.

DESCRIPTION
VIN Registration is an operation to registering VIN in ECM. It must be performed each time ECM is replaced.
NOTE:
Accurate VIN which is registered in ECM may be required for Inspection & Maintenance (I/M).
OPERATION PROCEDURE
With CONSULT-II
1. Check the VIN of the vehicle and note it. Refer to GI-49, "IDENTIFICATION INFORMATION" .
2. Turn ignition switch ON and engine stopped.
3. Select “VIN REGISTRATION” in “WORK SUPPORT” mode.
