SQUIB CIRCUIT CONNECTOR LOCK SWITCH
This mechanism prevents the improper deployment
of air bag module because of the current application
to the squib due to the static electricity when connec-
tors between SRS-ECU and air bag modules
(squibs) are disconnected. When the connector is
disconnected, the short spring short circuits the
power supply side terminal and ground side terminal
of squibs, and prevents the static electricity from
generating the potential difference. This connector
mechanism is adopted for the following connectors.
• SRS-ECU connector
• Connector between the clock spring and
body-side wiring harness
• Each air bag module connector
• Each pre-tensioner connector
• Intermediate connector between curtain air bag
module and SRS-ECU

WARNING
•
Do not repair, splice, or modify the SRS wiring (except for specific repairs to the instru-
ment panel wiring harness and the floor wiring harness shown on
): replace the
wiring if necessary, after reading and following all precautions and procedures in this
manual.
•
Do not use an analog ohmmeter to check the SRS wiring or components; use only the
special tools (refer to
) and a digital multi-meter (refer to
).
CAUTION
Improper services cause the system to be inoperative. Do not disassemble or tamper with the SRS
components to prevent the serious injury.
