Eº shows that current can flow in either direction depend-
ing on circuit operation.
p20System branchlThis shows that the system branches to another system identified by cell
code (section and system).
p21Page crossing
lThis arrow shows that the circuit continues to another page identified by cell
code.

p23Component box in wave
linelThis shows that another part of the component is also shown on another
page (indicated by wave line) within the system.
p24Component namelThis shows the name of a component.
p25Connector number
lThis shows the connector number.
lThe letter shows which harness the connector is located in.
Example:M: main harness. For details and to locate the connector, refer to
EL section (ªMain Harnessº, ªHARNESS LAYOUTº). A coordinate grid is
included for complex harnesses to aid in locating connectors.
p26Ground (GND)lThe line spliced and grounded under wire color shows that ground line is
spliced at the grounded connector.
p27Ground (GND)lThis shows the ground connection.
p28Connector viewslThis area shows the connector faces of the components in the wiring diagram
on the page.
p29Common componentlConnectors enclosed in broken line show that these connectors belong to the
same component.
p30Connector colorlThis shows a code for the color of the connector. For code meaning, refer to
wire color codes, Number
p14of this chart.
p31Fusible link and fuse box
lThis 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 cur-
rent flow out.
p32Reference arealThis shows that more information on the Super Multiple Junction (SMJ) and
Joint Connectors (J/C) exists on the foldout page.

CONNECTOR SYMBOLS
Most of connector symbols in wiring diagrams are shown from
the terminal side.
lConnector symbols shown from theterminal sideare
enclosed by asingle lineand followed by the direction mark
.
lConnector symbols shown from theharness sideare
enclosed by adouble lineand followed by the direction mark
.

lConnector numbers that indicate the harness side are
enclosed by a single line.
lConnector numbers that indicate components are enclosed
by a double line.
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:
lignition switch is in the ªLOCKº position,
ldoors, hood and trunk lid/back door are closed,
lpedals are not depressed, and
lparking brake is released.

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

REFERENCE AREA
The Reference Area of the wiring diagram contains references to
additional electrical reference pages at the end of the manual. If
connector numbers and titles are shown in the Reference Area
of the wiring diagram, these connector symbols are not shown
in the Connector Area.
Super multiple junction (SMJ)
In a wiring diagram, the SMJ connectors include a letter of the
alphabet in the terminal number. SMJ connector numbers are
shown in the Reference Area of the wiring diagram. SMJ termi-
nal arrangement can be found on the electrical reference pages
at the end of the manual. For terminal arrangement of these
connectors, refer to ªSUPER MULTIPLE JUNCTION (SMJ)º
electrical reference page at the end of the manual.
