On Board Self-Diagnosis FunctionNKS003KE
DESCRIPTION

Trouble diagnosis function of navigation system has a Self Diagnosis mode by automatic operation and a
Confirmation/Adjustment mode by manual operation.

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 display.

Confirmation/Adjustment mode displays trouble diagnosis that require an operation and a judgment by a
human (auto-decision cannot be performed by the system), confirmation of preset value, and an error his-
tory.
DIAGNOSIS ITEM
Mode Description
Self Diagnosis (DCU)

Display control unit diagnosis

Analyzes connection between the display control unit and each unit, and
operation of each unit.
Self Diagnosis (NAVI)

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

Analyzes connection between the NAVI control unit and the GPS
antenna.
Confirmation/
Adjustment Display Diagnosis
Color tone and shading of the display control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to display control unit can be performed
for Vehicle Speed, IGN, Reverse and Light.
Auto Climate Control Refer to ATC-52, "
Self-diagnosis Function" .
Navigation Display Diagnosis
Color tone and shading of the NAVI control unit-generated image can be
checked by the display of a color bar and a gray scale.
Vehicle Signals Diagnosis of signals that are input to NAVI control unit can be performed
for Vehicle speed, Lights, Ignition and Reverse.
Navigation Steering
Angle
Adjustment This mode is used to correct difference between actual turning angle of a
vehicle and turning angle of the vehicle mark on the display.
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 can
immediately restore system accuracy in cases such as when distance cal-
ibration is needed because of the use of tire chains.
Error History Malfunctions that occurred in the past are displayed, along with the num-
ber of times each has occurred. Time and location when/where the errors
occurred are also displayed.
Delete Unit Connection Log Erase the connection history of unit and error history.
CAN DIAG SUPPOPT MONITOR The transmitting/receiving of CAN communication can be monitored.

Vehicle Signals
A comparison check can be made of each actual vehicle signal and
the signals recognized by the NAVI control unit.
Navigation
Steering Angle Adjustment
The steering angle output value detected by the gyroscope can be
adjusted.
Speed Calibration
Usually the automatic distance correction function adjusts the mal-
function in distance caused by the tires wearing down or the tire
pressure change. If prompt adjustment is necessary when the tire
chains are installed, etc., perform this procedure.

ROUTE CALCULATION AND VISUAL GUIDANCE
The GPS indicator on the screen
remains gray. GPS signals cannot be received depending on
the vehicle location, such as in a parking
garage, on a road that has numerous tall build-
ings, etc. Drive on an open, straight road for a while.
A sufficient amount of GPS satellites is not
available. Please wait for the satellites to move to loca-
tions available for the navigation system.
The location of the vehicle mark is
misaligned from the actual posi-
tion. When using tire chains or replacing the tires,
speed calculations based on the speed sensor
may be incorrect. Drive the vehicle for a while [at approximately
30 km/h (19 MPH) for about 30 minutes] to
automatically correct the vehicle's mark posi-
tion. If this does not correct the vehicle mark
position, contact a NISSAN dealer or qualified
workshop.
The map data has a mistake or is incomplete
(the vehicle mark position is always misaligned
in the same area). Updated road information will be included in
the next version of the DVD-ROM.
Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The message “Error” appears. The DVD-ROM is dirty or partially damaged. Check the DVD-ROM and wipe it clean with a
soft cloth.
If any damage, replace the DVD-ROM.
Symptom Possible cause Possible solution
In the auto re-route calculation,
waypoints are not included. Waypoints that you have already passed are
not included in the auto re-route calculation. To go to that waypoint again, it is necessary to
edit the route.
Route information is not dis-
played. Route calculation has not yet been performed.
Set the destination and perform route calcula-
tion.
Vehicle is not driving on the suggested route. Drive on the suggested route.
Route guidance is set to off. Turn on the route guidance.
The auto re-route calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculations took priority conditions into
consideration, but the same route was calcu-
lated. This is not a malfunction.
A waypoint cannot be added. Five waypoints are already set on the route,
including the ones that you have already
passed. A maximum of 5 waypoints can be set on the
route. If you want to go to 6 or more waypoints,
perform route calculations several times, as
necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calcu-
lated. Reset the destination to a main or ordinary
road, and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far
away. Divide your trip by selecting one or two inter-
mediate destinations, and perform a global
route calculation based on multiple route cal-
culations.
There are time restricted roads (day of week,
time) near the current vehicle location or desti-
nation. Set [Use Time Restricted Roads] to off.
The part of the route already
passed is deleted. A route is managed by sections between way-
points. If passing the first waypoint, the section
between the starting point and the waypoint is
deleted. (It may not be deleted depending on
the area.) This is not a malfunction.

g. After installing rear timing chain case, check the surface height difference between the following parts on the oil pan (upper)
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.
a. Push plunger of timing chain tensioner (secondary) and keep it pressed in with a stopper pin. Standard
Rear timing chain case to cylinder block: –0.24 to 0.14 mm (–0.009 to 0.006 in)
SEM943G
Camshaft dowel pin hole (intake side): At cylinder head upper face side in each bank.
Camshaft dowel pin (exhaust side) : At cylinder head upper face side in each bank.

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.
c. After confirming the mating marks are aligned, tighten camshaft sprocket mounting bolts.

Secure camshaft using a wrench at the hexagonal portion to
tighten mounting bolts. Right bank : Use circle type.
Left bank : Use oval type.

d. Pull stopper pins out from timing chain tensioners (secondary).
6. Install tension guide.
7. Install timing chain (primary) as follows:
a. Install crankshaft sprocket.

Make sure the mating marks on crankshaft sprocket face the
front of the engine.
b. Install timing chain (primary).

Install timing chain (primary) so the mating mark (punched) on
camshaft sprocket is aligned with the pink 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).

4. Install timing chains and related parts.

Align the mating mark on each sprocket and timing chain for installation.
NOTE:
Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for
that on each sprocket for alignment.
CAUTION:
For the above reason, after the mating marks are aligned, keep them aligned by holding them
with a hand.

Install slack guides and tension guides onto correct side by checking with identification mark on sur-
face.

Install chain tensioner with plunger fixed as described in its removal.
CAUTION:

Before and after the installation of chain tensioner, make sure that the mating mark on timing
chain is not out of alignment.

After installing chain tensioner, remove stopper pin to release tensioner. Make sure tensioner
is released.

To avoid chain-link skipping of timing chain, do not move crankshaft or camshafts until front
cover is installed.

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.
