BRAKE BOOSTER
Revision: 2006 January2006 M35/M45
BRAKE BOOSTERPFP:47200
On-Board Inspection and ServiceNFS000P6
OPERATION CHECK
With engine stopped, change vacuum to atmospheric pressure by
depressing brake pedal several times. Then with brake pedal fully
depressed, start engine and when vacuum pressure reaches the
standard, make sure that clearance between brake pedal and floor
panel decreases.
AIR TIGHT CHECK
Run engine at idle for approximately 1 minute, and stop it after
applying vacuum to booster. Depress brake pedal normally to
change vacuum to atmospheric pressure. Make sure that dis-
tance at intervals of 5 seconds between brake pedal and floor
panel gradually increases.
Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change after
holding pedal down for 30 seconds.

LANE DEPARTURE WARNING SYSTEM
Revision: 2006 January2006 M35/M45
LANE DEPARTURE WARNING SYSTEM PFP:28442
Precautions for Lane Departure Warning (LDW) systemNKS003VF
WAR NING :
Lane Departure Warning (LDW) is only a warning device to inform the driver of an unintended lane
departure. It will not steer the vehicle or prevent loss of control. It is the driver's responsibility to stay
alert, drive safely, keep the vehicle in the traveling lane, and be in control of the vehicle at all times.
LDW system does not operate under the following conditions:
–At speeds below approx. 72 km/h (45 MPH).
–If it cannot detect lane markers.
LDW system may not function properly under the following conditions:
–On roads where a water puddle, dirt or snow is covering the lane markers.
–On roads where the lane markers are faded or are not painted clearly.
–On roads where the lane markers are painted yellow.
LDW system may not monitor the lane markers in certain road, weather or driving conditions.
–On roads where there are sharp curves.
–Where the traveling lane merges or separates.
–On roads where the discontinued lane markers are present, such as near tollgates, etc.
–On roads where there are not general lane markers.
–On roads where the lane width is too narrow.
–During bad weather (rain, fog, snow, etc.).
–When strong light (for example, at sunrise or sunset) is directly shining on the front of the vehicle.
–When entering or exiting a tunnel where sudden changes in brightness occur.
–When traveling close to the vehicle in front of you, which causes obstruction of the camera unit
range.
–When the vehicle's traveling direction does not align with the lane marker.
–When rain, snow or dirt adhere to the windshield in front of the camera unit.
Excessive noise interferes with warning system chime sound and the chime may not be heard.
CAUTION:
To keep the LDW system operating properly, be sure to observe the following:
Always keep the windshield clean. The sensing capability of the camera unit depends on the con-
dition of the windshield. See “Appearance and care” for cleaning instruction.
Never strike or damage the areas around the camera unit.
Never touch the camera lens.
Never attach a sticker (including transparent material) or install an accessory near the camera
unit.
Never place reflective materials, such as a white paper or mirrors on the instrument panel. Reflec-
tion of the sunlight may adversely affect the camera unit's lane marker detection capability.
System DescriptionNKS003VG
LDW SYSTEM OPERATION
The Lane Departure Warning (LDW) system warns the driver when the vehicle is traveling close to either
the left or the right of the traveling lane.
The system monitors lane markers of the traveling lane using the LDW camera unit. When the LDW cam-
era unit detects that the vehicle is traveling close to either the left or the right of the traveling lane, the
LDW indicator lamp flashes and a chime sounds to alert the driver.
NOTE:
When activating turn signal, LDW system does not give a warning to the lane marker on the turn signal
side.
The LDW system can be turned on or off by pushing the LDW switch. When the system is on, the LDW
system ON indicator illuminates.
The LDW system has an automatic mode and manual mode.

Camera Aiming AdjustmentNKS003VI
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.

ON BOARD DIAGNOSTIC (OBD) SYSTEM
Revision: 2006 January2006 M35/M45
ON BOARD DIAGNOSTIC (OBD) SYSTEMPFP:00028
IntroductionNBS004SL
The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
The above information can be checked using procedures listed in the table below.
: Applicable —: Not applicable
*: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to EC-108,
"Fail-Safe Chart" .)
Two Trip Detection LogicNBS004SM
When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic items will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.
: Applicable —: Not applicable
When there is an open circuit on MIL circuit, the ECM cannot warn the driver by lighting up MIL when there is
malfunction on engine control system.
