SEF289H
Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
SGI233
To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
SGI234
Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
Clean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
Replace oil seals, gaskets, packings, O-rings, locking washers,
cotter pins, self-locking nuts, etc. with new ones.
Replace inner and outer races of tapered roller bearings and
needle bearings as a set.
Arrange the disassembled parts in accordance with their
assembled locations and sequence.
Do not touch the terminals of electrical components which use
microcomputers (such as ECMs).
Static electricity may damage internal electronic components.
After disconnecting vacuum or air hoses, attach a tag to indi-
cate the proper connection.
Use only the fluids and lubricants specified in this manual.
Use approved bonding agent, sealants or their equivalents
when required.
Use tools and recommended special tools where specified for
safe and efficient service repairs.
When repairing the fuel, oil, water, vacuum or exhaust
systems, check all affected lines for leaks.
Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.

Number Item Description
1 Power conditionThis shows the condition when the system receives battery positive voltage (can be
operated).
2 Fusible linkThe double line shows that this is a fusible link.
The open circle shows current flow in, and the shaded circle shows current flow out.
3Fusible link/fuse loca-
tionThis shows the location of the fusible link or fuse in the fusible link or fusebox.For
arrangement, refer to EL-12, “POWER SUPPLY ROUTING”.
4FuseThe single line shows that this is a fuse.
The open circle shows current flow in, and the shaded circle shows current flow out.
5 Current rating This shows the current rating of the fusible link or fuse.
6 ConnectorsThis shows that connector E3 is female and connector M1 is male.

Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is SMJ con-
nector. Refer to GI-20.
7 Optional splice The open circle shows that the splice is optional depending on vehicle application.
8 Splice The shaded circle shows that the splice is always on the vehicle.
9 Page crossingThis arrow shows that the circuit continues to an adjacent page.
The A will match with the A on the preceding or next page.
10 Common connectorThe dotted lines between terminals show that these terminals are part of thesamecon-
nector.
11 Option abbreviation This shows that the circuit is optional depending on vehicle application.
12 RelayThis shows an internal representation of the relay. For details, refer to EL-9, “STAN-
DARDIZED RELAY”.
13 Connectors This shows that the connector is connected to the body or a terminal with bolt or nut.
14 Wire colorThis shows a code for the color of the wire.

tion.
17 Assembly parts Connector terminal in component shows that it is a harness incorporated assembly.
18 Cell codeThis identifies each page of the wiring diagram by section, system and wiring diagram
page number.
19 Current flow arrowArrow indicates electric current flow, especially where the direction ofstandard flow (ver-
tically downward or horizontally from left to right) is difficult to follow.
A double arrow “
” shows that current can flow in either direction depending on cir-
cuit operation.
HOW TO READ WIRING DIAGRAMS

NOTICE:
Trouble diagnoses indicate work procedures required to diagnose
problems effectively. Observe the following instructions before
diagnosing.
1)Before performing trouble diagnoses, read the “Prelimi-
nary Check”, the “Symptom Chart” or the “Work Flow”.
2)After repairs, re-check that the problem has been com-
pletely eliminated.
3)Refer to Component Parts and Harness Connector Loca-
tion for the Systems described in each section for
identification/location of components and harness con-
nectors.
4)Refer to the Circuit Diagram for quick pinpoint check.
If you need to check circuit continuity between harness
connectors in more detail, such as when a sub-harness is
used, refer to Wiring Diagram in each individual section
and Harness Layout in EL section for identification of har-
ness connectors.
5)When checking circuit continuity, ignition switch should
be OFF.
6)Before checking voltage at connectors, check battery volt-
age.
7)After accomplishing the Diagnostic Procedures and Elec-
trical Components Inspection, make sure that all harness
connectors are reconnected as they were.
