Inspec'tion
For front seat belt retractors with seat belt tensioners.
reviewthe SRS component locations (see page 23-13)
and the precautions and procedures (see psge 23-14) in
the SRS section before performing repairs or service.
Retractor, Front and Rear
1. Before installing the retractor, check that the seat
belt can be pulled out freely.
2. l\4ake sure that the seat belt does not lock when the
retractor (A) is leaned slowly up to 15'from the
mounted position. The seat belt should lock when
the retractor is leaned over 40'. Do not attemDt to

Precautions and Procedures
General Precautions
Please read the following precautions carefully beforeperforming airbag system service. Observe theinstructions described in this manual. or the airbags
could accidentally deploy and cause damage or injuries.
. Except when performing electrical inspections.
always turn the ignition switch OFF, disconnect the
negative cable from the battery, and wait at least 3minutes before beginning work.
NOTE: The memory is not erased even if the ignition
switch is turned OFF or the battery cables are
disconnected from the battery.. Use replacement pans which are manufactured to the
same standards and quality as the original parts. Do
not install used SRS parts from another vehicle. Useonly new pans when making SRS repairs.. Carefully inspect any SRS part before you install it.
Do not install any part that shows signs of being
dropped or improperly handled, such as dents, cracks,
or deformation.
. Before removing any SRS parts (including the
disconnection of connectors), always disconnect the
SRS connector.. Use only a digital multimeter to check the system. lf itis not a Honda multimeter, make sure its outout is 10mA (0.01A) or less when switched to the lowest value
in the ohmmeter range. A tester with a higher output
could cause accidental deployment and possible
injury.. Do not put objects on the front passenger's airbag.. The original radio has a coded theft protection circuit.
Be sure to get the customer's radio code and write
down the frequencies for the radio's preset stations
before disconnecting the battery cable.. Before returning the vehicle to the customer, enter
the radio code. then enter the customer's radio
station presets, and set the clock. Do the engine
control module (ECM) idle learn procedure (see page
11-139).

Steering-related Plecautions
Cable Reel Alignment
. Misalignment of the cable reel could cause an open in
the wiring, making the SRS system and the horns
inoperative. Center the cable reel whenever the
following is performed (see step 6 on page 23-121).
- Installation of the steering wheel- Installation of the cable reel- Installation ofthe steering column- Other steering-related adjustment or installation
. Do not disassemble the cable reel.
. Do not apply grease to the cable reel.
. lf the cable reel shows any signs of damage or
contamination. replace it with a new one. For
example, it does not rotate smoothly.

Airbag Handling and Storage
Do not disassemble an airbag, lt has no serviceable
parts. Once an airbag has been deployed, it cannot be
repaired or reused.
For temporary storage of an airbag during service,
observe the following precautions.
. Store the removed airbag with the pad surface up.
Never put anything on the airbag.
To prevent damage to the airbag, keep it free from
any oil, grease, detergent, or water,
23-15
. Store the removed airbag on a secure, flat surface
away from any high heat source (exceeding 200'Fi
Never perform electrical inspections to the airbags,
such as measuring resistance.
Do not position yourself in front of the airbag during
removal, inspection, or replacement.
Refer to the scrapping procedures for disposal of a
damaged airbag.

Precautions and Procedures {cont'dl
SRS Unit, Front lmpact Sensors, and Side
lmpact Sensors
. Be careful not to bump or impact the SRS unit, front
impact sensors, or side impact sensors whenever the
ignition switch is ON (ll), or for at least 3 minules after
the ignition switch is turned OFF.
. During installation orreplacement, be careful notto
bump (by impact wrench, hammer, etc.) the area
around the SRS unit, front impact sensors, and sjde
impact sensor. The airbags could accidentally deploy
and cause damage or injury.
After a collision in which any airbags or seat belt
tensioners were deployed. replace the SRS unit, front
impact sensors, and other related components (see
page 23-112). After a collision in which a side airbag
was deployed. replace the side impact sensor on the
deployed side and the SRS unit. After a collision in
which the airbags or the side airbags did not deploy,
inspect for any damage or any deformation on the
SRS unit, front impact sensors, and the side impact
sensors. lf there is any damage, replace the SRS unit
and/or the sensors.
23-16
.j
. Do not disassemble the SRS unit, front impact sensors,
or side impact sensors.
. Turn the ignition switch OFF, disconnect the battery
negative cable, and wait at least 3 minules before
beginning installation or replacement of the SBS unit,
or disconnecting the connectors from the SRS unit.
. Be sure the SRS unit, front impact sensors, and side
impact sensors are installed securely. with the
mounting bolts torqued to 9.8 N.m (1.0 kgf.m,7.2 lbf.ft)
. Do not spill wateroroil on the SRS unit, front impact
sensors, or the side impact sensors, and keep them
away from dust.
. Store the SRS unit, front imDact sensors and side
impact sensors in a cool (less than 104"F/40'C) and
dry (less than 80 % relative humidity, no moisture)
area.

Precautions and Procedures (cont'dl
Spring-loaded Lock Connector
Some SRS system connectors have a spring-loaded
lock.
Front Airbag Connectors:
Disconnecting
To release the lock. pullthe spring-loaded sleeve (A)
toward the stop (B) while holding the opposite half of
the connector. Then pullthe connector halves apart, Be
sure to pull on the sleeve and not on lhe connector.
Connecting
1. To reconnect, hold the pawl-side connector, andpress 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 (C). Do not touch the sleeve.
When the connector halves are completelV
connected, the pawl is released, and the spring-
loaded sleeve locks the connector.

Side Airbag Connector:
Disconnecting
To release the lock, pullthe spring-loaded sleeve (A)
and the slider {B) while holding the opposite half of the
connector. Then pullthe connector halves apart. Be
sure to pull on the sleeve and not on the connector half.
Connecting
Hold both connector halves, and press them firmly
together until the projection (C) of the sleeve side
connector clicks.J
