ESP NISSAN PATROL 1998 Y61 / 5.G General Information Workshop Manual

General Precautions
+Do not operate the engine for an extended period of time with-
out proper exhaust ventilation.
Keep the work area well ventilated and free of any in¯ammable
materials. Special care should be taken when handling any
in¯ammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.
+Before jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before work-
ing on the vehicle.
These operations should be done on a level surface.
+When removing a heavy component such as the engine or
transaxle/transmission, be careful not to lose your balance and
drop it. Also, do not allow it to strike adjacent parts, especially
the brake tubes and master cylinder.
+Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
+To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
+Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.

Number Item Description
V19Current ¯ow arrow+Arrow indicates electric current ¯ow, especially where the direction of standard
¯ow (vertically downward or horizontally from left to right) is difficult to follow.
+A double arrow ``bÐ
c'' shows that current can ¯ow in either direction depending
on circuit operation.
V20System branch+This shows that the system branches to another system identi®ed by cell code
(section and system).
V21Page crossing+This arrow shows that the circuit continues to another page identi®ed by cell code.
+The C will match with the C on another page within the system other than the
next or preceding pages.
V22Shielded line+The line enclosed by broken line circle shows shield wire.
V23Component box in wave
line+This shows that another part of the component is also shown on another page
(indicated by wave line) within the system.
V24Component name+This shows the name of a component.
V25Connector number+This shows the connector number.
+The letter shows which harness the connector is located in.
Example:M: main harness. For detail and to locate the connector, refer to EL sec-
tion (``Main Harness'', ``HARNESS LAYOUT''). A coordinate grid is included for
complex harnesses to aid in locating connectors.
V26Ground (GND)+The line spliced and grounded under wire color shows that ground line is spliced
at the grounded connector.
V27Ground (GND)+This shows the ground connection.
V28Connector views+This area shows the connector faces of the components in the wiring diagram on
the page.
V29Common component+Connectors enclosed in broken line show that these connectors belong to the
same component.
V30Connector color+This shows a code for the color of the connector. For code meaning, refer to wire
color codes, NumberV14of this chart.
V31Fusible link and fuse box+This shows the arrangement of fusible link(s) and fuse(s), used for connector
views of ``POWER SUPPLY ROUTING'' in EL section.
The open square shows current ¯ow in, and the shaded square shows current
¯ow out.
V32Reference area+This shows that more information on the Super Multiple Junction (SMJ) and Joint
Connectors (J/C) exists on the foldout page. Refer to GI-16 for details.

How to Follow This Flow Chart
Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in
enclosed blocks, as shown in the following example.
CHECK POWER SUPPLY.
1) Turn ignition switch ``ON''.
2) Check voltage between terminal
V1and ground.
Battery voltage should exist.
bCheck item being performed.
Procedure, steps or
measurement results
Measurement results
Required results are indicated in bold type in the correspond-
ing block, as shown below:
These have the following meanings:
Battery voltage®11 - 14V or approximately 12V
Voltage: Approximately 0V®Less than 1V
Cross reference of work symbols in the text and
illustrations
Illustrations are provided as visual aids for work procedures.
For example, symbol
indicated in the left upper portion of
each illustration corresponds with the symbol in the ¯ow chart
for easy identi®cation. More precisely, the procedure under the
``CHECK POWER SUPPLY'' outlined previously is indicated by
illustration
.
Symbols used in illustrations
Symbols included in illustrations refer to measurements or pro-
cedures. Before diagnosing a problem, familiarize yourself with
each symbol.
