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 systemÐair 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.
