TESTING FOR “SHORTS” IN THE CIRCUITNJGI0005S0303To simplify the discussion of shorts in the system please refer to
the schematic below.
SGI847
Resistance Check Method
1) Disconnect the battery negative cable and remove the blown
fuse.
2) Disconnect all loads (SW1 open, relay disconnected and sole-
noid disconnected) powered through the fuse.
3) Connect one probe of the ohmmeter to the load side of the fuse
terminal. Connect the other probe to a known good ground.
4) With SW1 open, check for continuity.
continuity; short is between fuse terminal and SW1 (point A).
no continuity; short is further down the circuit than SW1.
5) Close SW1 and disconnect the relay. Put probes at the load
side of fuse terminal and a known good ground. Then, check
for continuity.
continuity; short is between SW1 and the relay (point B).
no continuity; short is further down the circuit than the relay.
6) Close SW1 and jump the relay contacts with jumper wire. Put
probes at the load side of fuse terminal and a known good
ground. Then, check for continuity.
continuity; short is between relay and solenoid (point C).
no continuity; check solenoid, retrace steps.
Voltage Check Method
1) Remove the blown fuse and disconnect all loads (i.e. SW1
open, relay disconnected and solenoid disconnected) powered
through the fuse.
2) Turn the ignition key to the ON or START position. Verify bat-
tery voltage at the B + side of the fuse terminal (one lead on
the B + terminal side of the fuse block and one lead on a known
good ground).
3) With SW1 open and the DMM leads across both fuse
terminals, check for voltage.
voltage; short is between fuse block and SW1 (point A).
no voltage; short is further down the circuit than SW1.
4) With SW1 closed, relay and solenoid disconnected and the
DMM leads across both fuse terminals, check for voltage.
voltage; short is between SW1 and the relay (point B).

HOW TO PERFORM EFFICIENT DIAGNOSES FOR AN ELECTRICAL INCIDENT
Circuit Inspection (Cont’d)
GI-27

On Board Diagnosis LogicNJEC1258The ECM checks if battery voltage is within the tolerance range for the engine control system.
This self-diagnosis has the one trip detection logic.
The MI will not light up for this self-diagnosis.

Battery
Alternator
ECM
DTC Confirmation ProcedureNJEC1259With CONSULT-II
1) Check the following.
Jumper cables are connected for jump starting.
Battery or alternator has been replaced.
If the result is “Yes” for one item or more, skip the following steps and go to“Diagnostic Procedure”,
EC-183.
2) Check that the positive battery terminal is connected to battery properly. If NG, reconnect it properly.
3) Check that the alternator functions properly. Refer to SC-29, “TroubleDiagnosis”.
4) Turn ignition switch “ON” and select “DATA MONITOR” mode with CONSULT-II.
5) Wait one minute.
6) If DTC is detected, go to “Diagnostic Procedure”, EC-183.
If DTC is not detected, go to next step.
7) Start engine and wait one minute at idle.
8) If DTC is detected, go to “Diagnostic Procedure”, EC-183.
Without CONSULT-II
1) Check the following.
Jumper cables are connected for jump starting.
Battery or alternator has been replaced.
If the result is “Yes” for one item or more, skip the following steps and go to“Diagnostic Procedure”,
EC-183.
2) Check that the positive battery terminal is connected to battery properly. If NG, reconnect it properly.
3) Check that the alternator functions properly. Refer to SC-29, “TroubleDiagnosis”.
4) Turn ignition switch “ON” and wait one minute.
5) Turn ignition switch “OFF”, wait 5 seconds and then turn “ON”.
6) Perform “Diagnostic Test Mode II (Self-diagnostic result)” with ECM.
7) If DTC is detected, go to “Diagnostic Procedure”, EC-183.
If DTC is not detected, go to next step.
8) Start engine and wait one minute at idle.
9) Turn ignition switch “OFF”, wait 5 seconds and then turn “ON”.
10) Perform “Diagnostic Test Mode II (Self-diagnostic result)” with ECM.
11) If DTC is detected, go to “Diagnostic Procedure”, EC-183.

Cause (condition) -:While driving ooo:Display Driving condition Remarks (correction, etc.)
Precautions
for drivingJust after the engine is startedIf the vehicle is driven off just after the
engine is started when the gyroscope
(angular speed sensor) correction is
not completed, the vehicle can lose its
direction and may have deviated from
the correct location.Wait for a short while before driv-
ing after starting the engine.
Continuous driving without stoppingWhen driving long distances without
stopping, direction errors may
accumulate, and the current-location
mark may deviate from the correct
road.Stop and adjust the orientation.
Abusive drivingSpinning the wheels or engaging in
other kinds of abusive driving may
result in the system being unable to
perform correct detection, and may
cause the vehicle mark to deviate from
the correct road.If after travelling about 10 km (6
miles) the correct location has not
been restored, perform location
correction and, if necessary,
direction correction.
How to cor-
rect locationPosition correction accuracy
SEL699V
If the accuracy of location settings is
poor, accuracy may be reduced when
the correct road cannot be found, par-
ticularly in places where there are
many roads.Enter in the road displayed on
the screen with an accuracy of
approx. 1 MM.
NOTE:
Whenever possible, use detailed
map for the correction.
Direction when location is corrected
SEL702V
If the accuracy of location settings dur-
ing correction is poor, accuracy may
be reduced afterwards.Perform direction correction.
THE CURRENT POSITION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG.NJEL0633S07In the following cases, the current-location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case,perform location correction and
direction correction.
When location correction has not been done
− If the receiving conditions of the GPS satellite signal is poor, if the current-location mark becomes out of
place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.
When the vehicle has traveled by ferry, or when the vehicle has been being towed
− Because calculation of the current location cannot be done when travelling with the ignition OFF, for
example when traveling by ferry or when being towed, the location before travel is displayed. If the pre-
cise location can be detected with GPS, the location will be corrected.
THE CURRENT POSITION MARK JUMPS.NJEL0633S08In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.
When map matching has been done
− If the current location and the current-location mark are different whenmap matching is done, the current-
location mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a
location which is not on a road.
When GPS location correction has been done
− If the current location and the current-location mark are different whenthe location is corrected using GPS

How to Handle BatteryNJSC0003CAUTION:
If it becomes necessary to start the engine with a booster
battery and jumper cables,
1) Use a 12-volt booster battery.
2) After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
3) Never add distilled water through the hole used to check
specific gravity.

METHODS OF PREVENTING OVER-DISCHARGENJSC0003S01The following precautions must be taken to prevent over-discharg-
ing a battery.
The battery surface (particularly its top) should always be kept
clean and dry.
The terminal connections should be clean and tight.
At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as “low maintenance”
and “maintenance-free”.
MEL041F
When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
MEL042F
Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVELNJSC0003S02WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.
