Symptom Possible cause Repair order
No route is displayed.No object route is searched near destination
area.Adjust position to wide road (brown) near des-
tination area. In an area where traffic direction
is displayed separately, pay close attention to
the direction of travel. Set the destination area
and the way point over the road.
Starting point and destination areas are very
near.Move destination areas away from starting
point on the screen.
Recommended route which has
been passed disappears from the
display.The recommended route is divided into indi-
vidual control segments. When way point 1 is
passed, the data from the starting point to the
way point 1 is erased.This is not abnormal.
Search recommends roundabout
route.There may be special conditions for roads
near the starting point and destination area
(one-way traffic, etc.). A roundabout route may
be displayed.Slightly change starting point and destination
area settings.
Landmark display does not show
actual conditions.Mistaken or missing map data may result in
erroneous display.Change map CD.
Recommended route drawn
slightly away from starting point,
way points, and destination area.Course search data may not exist for closely
positioned starting point, way points, and des-
tination area shown on the map. Route guide
starting point, way point, and destination point
may be separated.Set the destination area to the general route
(indicated by a thick brown line). However,
even if the selected route is a major one,
appropriate route search data may not be
available.
LOCATION OF CAR MARKERNJEL0526S04+If the vehicle has been parked in a multi-level parking facility or underground parking facility, the car marker
position may be inaccurate immediately after exiting the parking facility.
+The GPS accuracy is within±100 m (300 ft). Even when receiving conditions are excellent, further posi-
tional correction may not occur.
STREET INDICATIONNJEL0526S05+Street names displayed on the map may differ from the actual street names.
+An ªUnknown streetº message may appear on the map in place of street name information.
RESEARCHNJEL0526S06+Position may be searched by house number. However, the displayed position and street may differ from
the actual position and street.
+When position is searched using POI, the displayed position may differ from the actual position.
+Some data may not be available for new buildings and other structures in a map.
GPS ANTENNANJEL0526S07+Do not place metal objects above the GPS antenna mounted on the rear parcel shelf. This will cause
interference with signal reception.
+Do not place mobile telephones or vehicle radio transceivers in close proximity to the GPS antenna
mounted on the rear parcel shelf. This may cause interference with signal reception.

STEP DESCRIPTION
STEP 1 Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:
WHATVehicle Model, Engine, Transmission and the System (i.e. Radio).
WHENDate, Time of Day, Weather Conditions, Frequency.
WHERERoad Conditions, Altitude and Traffic Situation.
HOWSystem Symptoms, Operating Conditions (Other Components Interaction).
Service History and if any After Market Accessories have been installed.
STEP 2 Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem can not be duplicated, refer to ªIncident Simulation Testsº next page.
STEP 3 Get the proper diagnoses materials together including:
POWER SUPPLY ROUTING
System Operation Descriptions
Applicable Service Manual Sections
Check for any Service Bulletin.
Identify where to begin diagnoses based upon your knowledge of the system operation and the cus-
tomer comments.
STEP 4 Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing
and Harness Layouts.
STEP 5 Repair or replace the incident circuit or component.
STEP 6 Operate the system in all modes. Verify the system works properly under all conditions. Make sure you
have not inadvertently created a new incident during your diagnoses or repair steps.

The second method is to put the suspect component into a freezer
long enough for any water to freeze. Reinstall the part into the car
and check for the reoccurrence of the incident. If it occurs, repair
or replace the component.
SGI844
WATER INTRUSIONNJGI0005S0205The incident may occur only during high humidity or in rainy/snowy
weather. In such cases the incident could be caused by water
intrusion on an electrical part. This can be simulated by soaking the
car or running it through a car wash.
Do not spray water directly on any electrical components.
SGI845
ELECTRICAL LOADNJGI0005S0206The incident may be electrical load sensitive. Perform diagnoses
with all accessories (including A/C, rear window defogger, radio,
fog lamps) turned on.
COLD OR HOT START UPNJGI0005S0207On some occasions an electrical incident may occur only when the
car is started cold. Or it may occur when the car is restarted hot
shortly after being turned off. In these cases you may have to keep
the car overnight to make a proper diagnoses.
Circuit InspectionNJGI0005S03INTRODUCTIONNJGI0005S0301In general, testing electrical circuits is an easy task if it is
approached in a logical and organized method. Before beginning
it is important to have all available information on the system to be
tested. Also, get a thorough understanding of system operation.
Then you will be able to use the appropriate equipment and follow
the correct test procedure.
You may have to simulate vehicle vibrations while testing electrical
components.Gently shakethe wiring harness or electrical com-
ponent to do this.
OPEN A circuit is open when there is no continuity through a section of
the circuit.
SHORT There are two types of shorts.
+SHORT CIRCUIT When a circuit contacts another circuit
and causes the normal resistance to
change.
+SHORT TO GROUND When a circuit contacts a ground source
and grounds the circuit.
