Circuit Breaker
The circuit breaker is a protective device designed to
open the circuit when a current load is in excess of rated
breaker capacity. If there is a short or other type of
overload condition in the circuit, the excessive current will
open the circuit between the circuit breaker terminals.
The reset knob (1) pops out when the circuit is open. Push
the reset knob in place to restore the circuit after repairing
it.
Relay
Battery and load location may require that a switch be
placed some distance from either component. This
means a longer wire and a higher voltage drop (1).
The installation of a relay between the battery and the
load reduces the voltage drop (2).
Because the switch controls the relay, amperage through
the switch can be reduced.

Connector
The connector pin shape (2) determines whether the
connector is male (3) or female (1).
The symbol illustrated in the figure is used as connector,
in the circuit of this section.

Connector terminal numbers (10) are clearly shown.
Male side connector (9) terminal numbers are in
sequence from upper right to lower left.
Female side connector (8) terminal numbers are in
sequence from upper left to lower right.
NOTE:
1. For those connectors on which specific terminal
numbers or symbols are shown (such as PCM), the
terminal numbers or symbols are used in the circuit
diagram, irrespective of the above rule.
Refer to the following figure.2. The connectors used for relays have their own terminal
number assignment, irrespective of the above rule.
Refer to the following figure.
Double Lock Type Connector
Double lock type yellow color connectors are used for
supplemental restraint system–air bag circuit. When
removing the cable harness, disconnect the connector by
unlocking at two places, outside (1) and inside (2). In such
a case, do not pull the cables. Otherwise, cable
disconnection may occur.
When connecting the connector, insert the connector
completely and lock at outside. Imperfect locking may
cause malfunction of SRS system circuit.
