Prior to performing trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to AV- 1 5 2 , "

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.

DVD-ROM
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.

Be careful not to drop mounting bolt inside timing chain
case.
b. Loosen upper mounting bolt slowly, and then turn chain ten- sioner (primary) on the mounting bolt so that plunger is fully
expanded.
NOTE:
Even if plunger is fully expanded, it is not dropped from the body
of timing chain tensioner (primary).
c. Turn crankshaft pulley clockwise so that timing chain on the tim- ing chain tensioner (primary) side is loose.
d. Remove upper mounting bolt, and then remove timing chain ten- sioner (primary).
CAUTION:
Be careful not to drop mounting bolt inside timing chain
case.
8. Remove water pump as follows:
a. Remove three water pump mounting bolts. Secure a gap between water pump gear and timing chain, by turning crank-
shaft pulley counterclockwise until timing chain looseness on
water pump sprocket becomes maximum.
