HOW TO READ CIRCUIT DIAGRAMSM1901000100704
The circuit of each system from the fuse (or fusible link) to ground is shown. The power supply is shown at
the top and the ground at the bottom to facilitate understanding of how the current flows. Some variations are
included in one circuit diagram.Accordingly, some diagrams may not be applicable for individual vehicles.

ITEM NO. CONNECTOR/ GROUNDING SYMBOL CONTENTS
Connector
and terminal
marking1 The male and female terminals
are indicated as shown. The
connector with male terminal(s)
is called as male connector and
indicated by two connector
contour lines, while the
connector with female
terminal(s) is called as female
connector and indicated by
single connector contour line.
Connector
symbol
marking2 The symbol indicates the
connector is viewed as shown.
At a device connection, the
connector symbol on the device
side is shown. For an
intermediate connector, the
male connector symbol is
shown. For spare connectors
and check connectors, no
device is connected, and so the
harness-side connector symbol
is shown for these connectors.

Connector
connection
marking3 Connection between a device
and the harness is either by
direct insertion in the device
(direct connection type) or by
connection with a harness
connector furnished on the
device side (harness
connection type). The two types
are indicated as illustrated. 4

Ground
marking6 Grounding is either by body
ground, device ground or
control unit interior ground.
These are indicated as
illustrated.
