NumberItem Description
q19Current flow arrowI
Arrow indicates electric current flow, especially where the direction of standard
flow (vertically downward or horizontally from left to right) is difficult to follow.
I A double arrow ªF Ð
Eº shows that current can flow in either direction depending on
circuit operation.
q20System branch I
This shows that the system branches to another system identified by cell code
(section and system).
q21Page crossing I
This arrow shows that the circuit continues to another page identified by cell code.
I The C will match with the C on another page within the system other than the next
or preceding pages.
q22Shielded line IThe line enclosed by broken line circle shows shield wire.
q23Component box in wave
line I
This shows that another part of the component is also shown on another page
(indicated by wave line) within the system.
q24Component name IThis shows the name of a component.
q25Connector number I
This shows the connector number.
I 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 (ªMain Harnessº, ªHARNESS LAYOUTº). A coordinate grid is included for com-
plex harnesses to aid in locating connectors.
q26Ground (GND) I
The line spliced and grounded under wire color shows that ground line is spliced
at the grounded connector.
q27Ground (GND) IThis shows the ground connection.
q28Connector views I
This area shows the connector faces of the components in the wiring diagram on
the page.
q29Common component I
Connectors enclosed in broken line show that these connectors belong to the
same component.
q30Connector color I
This shows a code for the color of the connector. For code meaning, refer to wire
color codes, Number q14of this chart.
q31Fusible link and fuse box I
This shows the arrangement of fusible link(s) and fuse(s), used for connector
views of ªPOWER SUPPLY ROUTINGº in EL section.
The open square shows current flow in, and the shaded square shows current
flow out.
q32Reference area I
This shows that more information on the Super Multiple Junction (SMJ) and Joint
Connectors (J/C) exists on the foldout page. Refer to GI-18 for details.

CONNECTOR SYMBOLS
Most of connector symbols in wiring diagrams are shown from the
terminal side.
IConnector symbols shown from the terminal side are enclosed
by a single line and followed by the direction mark
.
I Connector symbols shown from the harness side are enclosed
by a double line and followed by the direction mark
.
I Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

Harness indication
ILetter designations next to test meter probe indicate harness
(connector) wire color.
I Connector numbers in a single circle
M33indicate harness con-
nectors.
Component indication
I Connector numbers in a double circle indicate component con-
nectors.
SWITCH POSITIONS
Switches are shown in wiring diagrams as if the vehicle is in the
ªnormalº condition.
A vehicle is in the ªnormalº condition when:
Iignition switch is ªOFFº,
I doors, hood and trunk lid/back door are closed,
I pedals are not depressed, and
I parking brake is released.

DETECTABLE LINES AND NON-DETECTABLE LINES
In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
IA line with regular weight (wider line) represents a ªdetectable
line for DTC (Diagnostic Trouble Code)º. A ªdetectable line for
DTCº is a circuit in which ECM (Engine Control Module) can
detect its malfunctions with the on board diagnostic system.
I A line with less weight (thinner line) represents a ªnon-detect-
able line for DTCº. A ªnon-detectable line for DTCº is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.

FOLDOUT PAGE
The foldout page should be opened when reading wiring diagram.
Super multiple junction (SMJ)
In wiring diagram, connectors consisting of terminals having terminal numbers with an alphabet (1B, 0D, etc.)
are SMJ connectors.
If connector numbers are shown in Reference Area, these connector symbols are not shown in Connector
Area. For terminal arrangement of these connectors, refer to the foldout page at the end of this manual.
Joint connector
Joint connector symbols are shown in Connector Area in the wiring diagram concerned. Foldout page also
carries inside wiring layout together with such joint connector symbols.
