Some SRS system connectors have a spring-loaded
lock.
To release the lock, pull the spring-loaded sleeve (A)
toward the stop (B) while holding the opposite half of
the connector. Then pull the connector halves apart. Be
sure to pull on the sleeve and not on the connector.
1. To reconnect, hold the pawl-side connector, and
press on the back of the sleeve-side connector in
the direction shown. As the two connector halves
are pressed together, the sleeve (A) is pushed back
by the pawl (B). Do not touch the sleeve.
2. When the connector halves are completely
connected, the pawl is released, and the spring-
loaded sleeve locks the connector.
To release the lock, pull the spring-loaded sleeve (A)
and the slider (B) while holding the opposite half of the
connector. Then pull the connector halves apart. Be
sure to pull on the sleeve and not on the connector half.
Hold both connector halves, and press them firmly
together until the projection (C) of the sleeve-side
connector clicks.

SRS Short Canceller 070AZ-SAA0100
NOTE:
• To prevent damage of the connector cavity, insert the
SRS short canceller straight into the cavity from the
terminal side.
• Before installing the short canceller, wash it with
electrical contact cleaner, then air blow it dry.
• Do not use the short canceller if it is damaged.
• Make sure to remove the short canceller before re-
connecting.
When SRS unit connectors A or C are disconnected, a
short circuit is created in the connector by its own
function to prevent airbag deployment. The circuit may
need to be opened when diagnosis is done on the
circuit.
Insert the short canceller (No. 070AZ-SAA0100) in the
specified cavities when it is necessary to keep the
circuit open for diagnosis.
Terminal numbers are shown from the wire side of the
female terminals. Insert the short canceller(s) into the
cavities on the terminal side of the connector.

SIDE AIRBAG
LABEL
When checking voltage or resistance on this type of
connector the first time, you must remove the retainer
(A) to insert the tester probe from the wire side.
NOTE: It is not necessary to reinstall the removed
retainer; the terminals will stay locked in the connector
housing.
To remove the retainer (A), insert a flat-tip screwdriver
(B) between the connector body and the retainer, then
carefully pry out the retainer. Take care not to break the
connector.
Seats with side airbags have a ‘‘SIDE AIRBAG’’ label on
the seat-back.
• When cleaning, use a damp cloth to clean the seat.
Do not soak the seat with liquid.
• Do not spray steam on the seat.
• Do not repair a torn or frayed seat-back cover;
replace it.
• After a collision where the side airbag was deployed,
replace the seat-back cover and side airbag with new
parts. If the seat-back cushion is split, it must be
replaced. If the seat-back frame is deformed, it must
be replaced.
• Never put aftermarket accessories on the seat (covers,
pads, seat heaters, lights, etc.).
