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.

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