Description
Represents an interconnection between parts
using wiring harness or wire, and indicates its
signal name/contents. The arrow ">" or "<" on the
line represents the direction of signal flow.
Represents an interconnection between parts
using wiring harness or wire, which differs
according to the specifications, and indicates its
signal name/contents. The arrow ">" or "<" on the
line represents the direction of signal flow.
Represents a connection between parts using a
conductive member such as a plate spring, and
indicates its signal name/contents. The arrow ">"
or "<" on the line represents the direction of signal
flow.
Represents a function and a logical value (High
(H) or Low (L)) of a signal when the function is
activated. The voltage indicates a value when the
signal is High. The arrow indicates the direction of
signal flow.
Represents a function and a logical value (High
(H) or Low (L)) of a signal when the function is in
a detectable state. The voltage indicates a value
when the signal is High. The arrow indicates the
direction of signal flow.
Represents a connection between lead wires.
Represents a connection between parts by
tightening of a screw.
Represents a connection between "A" and "A".
The DC voltage indicates an approximate value
measured when the negative side is connected to
a signal ground (SG).
Indicates a signal ground (SG).
Indicates a frame ground (FG).
Indicates a return.
