Symbol Meaning Symbol Meaning
Fuse
•
Melts when current flow exceeds that
specified for circuit, interrupts current
flow.
Precautions
•
Do not replace with fuses exceeding
specified capacity.
Pump
•
Pulls in and discharges gases and
liquids.
Cigarette lighter
•
Electrical coil that generates heat.
Fuse (For high
current fuse)/
Fusible link
Accessory socket
•
Interior power supply.
Horn
•
Generates sound when current flows.
Speaker
Transistor (1)
•
Electrical switching component.
•
Turns on when voltage is applied to
the base (B).
Heater
•
Generates heat when current flows.
Transistor (2)
•
Reading code. Ignition switch
•
Turning ignition key switches circuit to
operate various component.
(NOTE)
Ignition switch is called engine switch
on diesel vehicles.
Switch (1)
Normally open
•
Allows or breaks current flow by
opening and closing curcuits. Harness
Connection
When circuit C-D
is connected to
circuit A-B, the
connection D is
indicated by a
black dot.
Selection
Diversion point D
for the different
circuits according
to the vehicle’s
specification is
indicated by a
white dot.
For vehicles with ABS, use the A-B
circuit.
For vehicles without ABS, use the C-B
circuit.
Switch (2)
Normally closed
Autostop switch
•
Automatically shuts off circuit when
certain conditions are met.
Relay (1)
Normally open
•
Current flowing through coil produces electromagnetic force causing contact to open or close.
