PHOW TO READ WIRING DIAGRAMS
Connector SymbolsINFOID:0000000003852766
Most of connector symbols in wiring diagrams are shown from the terminal side.
 Connector symbols shown from the terminal side are enclosed by
a single line and followed by the direction mark.
 Connector symbols shown from the harness side are enclosed by
a double line and followed by the direction mark.
 Certain systems and components, especially those related to
OBD, may use a new style slide-locking type harness connector.
For description and how to disconnect, refer to PG section,
“Description”, “HARNESS CONNECTOR”.
 Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

SWITCH POSITIONS
Switches are shown in wiring diagrams as if the vehicle is in the “normal” condition.
A vehicle is in the “normal” condition when:
Number Item Description
1 Power supply  This means the power supply of fusible link or fuse.
2 Fusible link  “X” means the fusible link.
3Number of fusible link/
fuse This means the number of fusible link or fuse location.
4 Fuse  “/” means the fuse.
5Current rating of fus-
ible link/fuse This means the current rating of the fusible link or fuse.
6 Optional splice  The open circle shows that the splice is optional depending on vehicle application.
7 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, .PG-83, "
How
To Read Harness Layout",PG-85, "Main Harness"
8Splice
 The shaded circle “ ” means the splice.
9 Page crossing  This circuit continues to an adjacent page.
10 Option abbreviation
 This means the vehicle specifications which layouts the circuit between “ ”.
11 Relay  This shows an internal representation of the relay.
12 Option description  This shows a description of the option abbreviation used on the page.
13 Switch This shows that continuity exists between terminals 1 and 2 when the switch is in the A
position. Continuity exists between terminals 1 and 3 when the switch is in the B position.
14 Circuit (Wiring)  This means the wiring.
15 System branch  This shows that the circuit is branched to other systems.
16 Shielded line  The line enclosed by broken line circle shows shield wire.
17 Component name  This shows the name of a component.
18 Ground (GND)  This shows the ground connection.
19 Connector This means the connector information.
 This unit-side is described by the connector symbols.
20 Connectors  This means that a transmission line bypasses two connectors or more.
21 Wire color This shows a code for the color of the wire.
B = Black
W = White
R = Red
G = Green
L = Blue
Y = Yellow
LG = Light GreenBR = Brown
OR or O = Orange
P = Pink
PU or V (Violet) = Purple
GY or GR = Gray
SB = Sky Blue
CH = Dark Brown
DG = Dark Green
 When the wire color is striped, the base color is given first, followed by the stripe color as
shown below:
Example: L/W = Blue with White Stripe
22 Terminal number  This means the terminal number of a connector.

HOW TO READ WIRING DIAGRAMS
 ignition switch is “OFF”,
 doors, hood and trunk lid/back door are closed,
 pedals are not depressed, and
 parking brake is released.
MULTIPLE SWITCH
The continuity of multiple switch is described in two ways as shown below.
 The switch chart is used in schematic diagrams.
 The switch diagram is used in wiring diagrams.

TIGHTENING TORQUE OF STANDARD BOLTS
TIGHTENING TORQUE OF STANDARD BOLTS
DescriptionINFOID:0000000003852910
This vehicle has both new standard based on ISO* and previous standard bolts/nuts. There are some differ-
ences between these two types of bolts/ nuts; shape of the head, grade of strength, hexagonal width across
flats and the standard tightening torque.
 For guidance in discriminating, refer to GI-14, "
Tightening Torque Table (New Standard Included)".
 The new standard machine screws and tapping screws have a head of ISO standard torx recess.
 If the tightening torque is not described in the description or figure, refer to GI-14, "
Tightening Torque Table
(New Standard Included)".
*ISO: International Organization for Standardization
Tightening Torque Table (New Standard Included)INFOID:0000000003852911
CAUTION:
 The special parts are excluded.
 The bolts/nuts in these tables have a strength (discrimination) number/symbol assigned to the head
or the like. As to the relation between the strength grade in these tables and the strength (discrimi-
nation) number/symbol, refer to “DISCRIMINATION OF BOLTS AND NUTS”.

CAUTION:
1. Use tightening torque with lubricant for the new standard bolts/nuts in principle. Friction coeffi-
cient stabilizer is applied to the new standard bolts/nuts.
2. However, use tightening torque without lubricant for the following cases. Friction coefficient stabi-
lizer is not applied to the following bolts/nuts.
