Num-
berItem Description
1 Power condition

This shows the condition when the system receives battery positive voltage (can be oper-
ated).
2 Fusible link

The double line shows that this is a fusible link.

The open circle shows current flow in, and the shaded circle shows current flow out.
3Fusible link/fuse loca-
tion

This shows the location of the fusible link or fuse in the fusible link or fuse box. For arrange-
ment, refer to PG section, POWER SUPPLY ROUTING.
4Fuse

The single line shows that this is a fuse.

The open circle shows current flow in, and the shaded circle shows current flow out.
5 Current rating

This shows the current rating of the fusible link or fuse.
6 Connectors

This shows that connector E3 is female and connector M1 is male.

The G/R wire is located in the 1A terminal of both connectors.

Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is SMJ connec-
tor. Refer to PG section, SMJ (SUPER MULTIPLE JUNCTION).
7 Optional splice

The open circle shows that the splice is optional depending on vehicle application.
8Splice

The shaded circle shows that the splice is always on the vehicle.
9 Page crossing

This arrow shows that the circuit continues to an adjacent page.

The A will match with the A on the preceding or next page.
10 Common connector

The dotted lines between terminals show that these terminals are part of the same connector.
11 Option abbreviation

This shows that the circuit is optional depending on vehicle application.
12 Relay

This shows an internal representation of the relay. For details, refer to PG section, STAN-
DARDIZED RELAY.
