On Board Self-Diagnosis FunctionAKS007IZ
DESCRIPTION

Diagnosis function consists of the self-diagnosis mode performed automatically and the CONFIRMATION/
ADJUSTMENT mode operated manually.

Self-diagnosis mode checks for connections between the units constituting this system, analyzes each
individual unit at the same time, and displays the results on the LCD screen.

CONFIRMATION/ADJUSTMENT mode is used to perform trouble diagnosis that require operation and
judgment by an operator (malfunction that cannot be automatically judged by the system), to check/
change the set value, and to display the History of Errors of the navigation system.
DIAGNOSIS ITEM
NOTE:
Make the status that is set by D/N function be shown. Mode Description
Self-diagnosis (DCU) Display control unit diagnosis
Self-diagnosis (NAVI)

NAVI Control unit diagnosis (DVD-ROM drive will not be diagnosed
when no map DVD-ROM is in it.)

Analyzes connection between the NAVI control unit and the GPS
antenna connection between the NAVI control unit and each unit, and
operation of each unit.
Confirmation/
Adjustment Display diagnosis
On display control unit mode, color tone and shading of the screen can be
checked by the display of a color bar and a gray scale.
Vehicle signals On display control unit mode, analyzes the following vehicle signals: Vehi-
cle speed signal, light signal
NOTE , ignition switch signal, and reverse sig-
nal.

Navigation Display diagnosis
On NAVI C/U mode, color tone and shading of the screen can be checked
by the display of a color bar and a gray scale.
Vehicle signals On NAVI C/U mode, analyzes the following vehicle signals: Vehicle speed
signal, light signal, ignition switch signal, and reverse signal.
History of Errors Diagnosis results previously stored in the memory (before turning ignition
switch ON) are displayed in this mode. Time and location when/where the
errors occurred are also displayed.
Navigation Display Longi-
tude & Latitude Display the map. Use the joystick to adjust position. Longitude and latitude
will be displayed.
Speed
Calibration Under ordinary conditions, the navigation system distance measuring
function will automatically compensate for minute decreases in wheel and
tire diameter caused by tire wear or low -pressure. Speed calibration
immediately restores system accuracy in cases such as when distance
calibration is needed because of the use of tire chains in inclement
weather.
Angle
adjustment Corrects difference between actual turning angle of a vehicle and turning
angle of the car mark on the display.
Initialize
Location This mode is for initializing the current location. Use when the vehicle is
transported a long distance on a trailer, etc.

NAVIGATION SYSTEM
Revision: 2005 July 2005 FX
Place In a parking lot When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.
If after traveling about 10km
(6miles) the correct location
has not been restored, perform
location correction and, if nec-
essary, direction correction.
Turn ta ble
When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be
easily returned to after rotating the vehicle
on a turn table with the ignition OFF.
Slippery roads On snow, wet roads, gravel, or other roads where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.
Slopes When parking in sloped garages, when traveling on banked roads, or in other
cases where the vehicle turns when tilted,
an error in the turning angle will occur, and
the vehicle mark may deviate from the
road.
Map data Road not displayed on the map screen
When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.
Different road pattern
(Changed due to repair) If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the
correct road.
Vehicle Use of tire chains When tire chains are used, the mileage is
not correctly detected, and the vehicle
mark may deviate from the correct road. Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.)

mounting surface.

If not within the standard, repeat the installation procedure.
3. Install water pump with new O-rings. Refer to CO-22, "
WATER PUMP" .
4. Make sure that dowel pin hole, dowel pin and crankshaft key are located as shown in the figure. (No. 1 cylinder at compression
TDC)
NOTE:
Though camshaft does not stop at the position as shown in the
figure, for the placement of cam nose, it is generally accepted
camshaft is placed for the same direction of the figure.
CAUTION:
Hole on small dia. side must be used for intake side dowel pin hole. Do not misidentify (ignore big
dia. side).
5. Install timing chains (secondary) and camshaft sprockets as follows: CAUTION:
Mating marks between timing chain and sprockets slip easily. Confirm all mating mark positions
repeatedly during the installation process. Bolt length: Bolt position

a. Push plunger of timing chain tensioner (secondary) and keep it
pressed in with a stopper pin.
b. Install timing chains (secondary) and camshaft sprockets.

Align the mating marks on timing chain (secondary) (gold link)
with the ones on intake and exhaust camshaft sprockets
(punched), and install them.
NOTE:

Mating marks for intake camshaft sprocket are on the back
side of camshaft sprocket (secondary).

There are two types of mating marks, circle and oval types.
They should be used for the right and left banks, respec-
tively.

Align dowel pin and pin hole on camshafts with the groove
and dowel pin on sprockets, and install them.

On the intake side, align pin hole on the small diameter side of
the camshaft front end with dowel pin on the back side of
camshaft sprocket, and install them.

On the exhaust side, align dowel pin on camshaft front end
with pin groove on camshaft sprocket, and install them.

In case that positions of each mating mark and each dowel
pin are not fit on mating parts, make fine adjustment to the
position holding the hexagonal portion on camshaft with wrench or equivalent.

Mounting bolts for camshaft sprockets must be tightened in the next step. Tightening them by hand is
enough to prevent the dislocation of dowel pins.

It may be difficult to visually check the dislocation of mating
marks during and after installation. To make the matching
easier, make a mating mark on the top of sprocket teeth and
its extended line in advance with paint.

TIMING CHAIN
Revision: 2005 July 2005 FX

Install timing chain (primary) so the mating mark (punched) on
camshaft sprocket is aligned with the yellow link on timing
chain, while the mating mark (notched) on crankshaft
sprocket is aligned with the orange one on timing chain, as
shown in the figure.

When it is difficult to align mating marks of timing chain (pri-
mary) with each sprocket, gradually turn camshaft using
wrench on the hexagonal portion to align it with the mating
marks.

During alignment, be careful to prevent dislocation of mating
mark alignments of timing chains (secondary).
8. Install internal chain guide, slack guide and timing chain ten- sioner (primary).

CAUTION:

All applicable state or Provincial (in Canada) laws and local laws regarding the towing operation
must be obeyed.

It is necessary to use proper towing equipment to avoid possible damage to the vehicle during
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.

Always attach safety chains before towing.

When towing, make sure that the transmission, steering system and powertrain are in good order.
If any unit is damaged, dollies must be used.

Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI recommends that vehicle be towed with the driving (rear) wheels off the ground or that a dolly be
used as illustrated.
CAUTION:

Never tow automatic transmission models with the rear wheels on the ground or four wheels on
the ground (forward or backward), as this may cause serious and expensive damage to the trans-
mission.
If it is necessary to tow the vehicle with the front wheels raised, always use towing dollies under
the rear wheels.

When towing rear wheel drive models with the front wheels on the ground or on towing dollies:
–Turn the ignition key to the OFF position, and secure the steering wheel in a straight ahead posi-
tion with a rope or similar device.Never secure the steering wheel by turning the ignition key to the
LOCK position. This may damage the steering lock mechanism.
–Move the selector lever to the N (Neutral) position.

When the battery of vehicle equipped with the Intelligent Key system is discharged, your vehicle
should be towed with the front wheels on towing dollies or place the vehicle on a flat bed truck.
If the speed or distance must necessarily be greater, remove the propeller shaft before towing to prevent dam-
age to the transmission.
