Number Item Description
20 System branchThis shows that the system branches to another system identified by cell code (section
and system).
21 Page crossingThis arrow shows that the circuit continues to another page identified by cell code.
The C will match with the C on another page within the system other than the next or
preceding pages.
22 Shielded line The line enclosed by broken line circle shows shield wire.
23Component box in
wave lineThis shows that another part of the component is also shown on another page (indicated
by wave line) within the system.
24 Component name This shows the name of a component.
25 Connector numberThis 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-556, “Main
Harness”. A coordinate grid is included for complex harnesses to aid in locating connec-
tors.
26 Ground (GND)The line spliced and grounded under wire color shows that ground line is spliced at the
grounded connector.
27 Ground (GND)This shows the ground connection. For detailed ground distribution information, refer to
EL-24, “GROUND DISTRIBUTION”.
28 Connector viewsThis area shows the connector faces of the components in the wiring diagramon the
page.
29 Common componentConnectors enclosed in broken line show that these connectors belong to thesamecom-
ponent.
30 Connector colorThis shows a code for the color of the connector. For code meaning, refer to wire color
codes, Number 14 of this chart.
31Fusible link and fuse
boxThis 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 flow in, and the shaded square shows current flow out.
32 Reference areaThis shows that more information on the Super Multiple Junction (SMJ), Electrical Units,
exists at the end of the manual. Refer to GI-20 for details.

been detected in ECM—
*: When NATS detects trouble, the security indicator lights up while ignition key is in the “ON” position.
*: When the vehicle is equipped with a dongle unit (RHD models for Europe), the security indicator blinks 6 times just after the ignition
switch is turned to ON. Then the security indicator lights up while the ignition key is in the “ON” position.
