In-vehicle
1. Check that the seat belt is not twisted or caught on
anything.
2. After installing the anchors. check for free
movement on the anchor bolts. lf necessary,
remove the anchor bolts and check that the
washers and other parts are not damaged or
improperly installed.
3. Check the seat belts for damage or discoloration.
Clean with a shop towel if necessary. Use only
soap and water to clean.
NOTE: Dirt build-up in the loops of the upper
anchors can cause the seat belts to retract slowly.
Wipe the inside of the loops with a clean cloth
dampened in lsopropyl alcohol.
Check that the seat belt does not lock when pulled
out slowly. The seat belt is designed to lock only
during a sudden stop or impact.
For rear center shoulder belt, check that the seat
belt locks when pulled out over 400 mm (15.7 in.)
with the seat-back folded down.
Make sure that the seat belt will retract
automatically when released.
For each passenger's seat belt, check the seat belt
retractor locking mechanism ALR (automatic
locking retractor). This function is for securing child
seats.
-1 Pullthe seat belt allthe way outto engage the
ALR. The seat belt should retract with a
ratcheting sound, but not extend. This is
normal.
-2 To disengage the ALR, release the seat belt and
allow itto fully retract, then pullthe seat belt
out part-way. The seat belt should retract and
extend normally.
Replace the seat belt with a new assembly if there
is any abnormality. Do not disassemble any part of
the seat belt for any reason.

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.

. 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
Disconnecting System Connectors
Before removing a front airbag. side airbag, or other SRS related devices {the SRS unit, the cable reel, the front impact
sensors, the side impact sensors, the seat belt buckle tensioners, and the seat belt tensioner connector), disconnectingconnectors from related devices, or removing the dashboard or the steering column, disconnect the airbag connectorsor the side airbag connectors to prevent accidental deploVment.
Turn the ignition switch OFF, disconnect the negative cable from the battery, and wait at least 3 minutes before
beginning the following procedures.'BeforedisconnectingSRSunitconnectorA(1)fromtheSRSunit,disconnectthedriver'sairbag4Pconnector(3).
the front passenger's airbag 4P connector (4), the driver's seat belt tensioner 2P connector (6), and the frontpassenger's seat belt tensioner 2P connector (7).
. Before disconnecting SRS unit connector B (8) from the SRS unit, disconnect both side airbag 2P connectors (11. '12),
and both seat belt buckle tensioner 4P connectors (9, 10).. Before disconnecting the cable reel 4P connector (2), disconnect the driver's airbag 4P connector (3).'Beforedisconnectingthefloorwireharness4Pconnector(5),disconnectbothseatbelttensioner2Pconnectors

General Troubleshooting Information
DTC (Diagnostic Trouble Codesl
The self-diagnostic function of the SRS system allows it
to locate the causes of system problems and then store
this information in memory. For easier troubleshooting,
this data can be retrieved via a data link circuit.
. When you turn the ignition switch ON (ll), the SRS
indicator will come on. lf it goes off after 6 seconds,
the system is normal.. lf there is an abnormality, the svstem locates and
defines the problem, stores this information in
memory, and turns the SRS indicator on. The data
will remain in the memory even when the ignition
switch is turned off or if the battery is disconnected.. When you connect the Honda PG lM Tester to the 16P
data link connector (DLC)to short the SCS terminal,
and turn the ignition switch ON (ll). the SRS indicator
will indicate the diagnostic trouble code (DTC) by the
number of blinks.. When you connect the Honda PGM Tester to the 16P
data link Connector (DLC), you can retrieve the DTC in
the Honda Systems "SRS" menu.. After reading and recording the DTC, proceed with
the troubleshooting procedure for th is code.
Precautions. Use only a digital multimeter to check the system. lf
it's not a Honda multimeter, make sure its output is
10 mA (0.01A) or less when switched to the smallest
value in the ohmmeter range, A tester with a higher
output could damage the airbag circuit or cause
accidental airbag deployment and possible injury.. Whenever the ignition switch is ON (ll), or has been
turned OFF for less than 3 minutes, be careful not to
bump the SRS uniU the airbags could accidentally
deploy and cause damage or injuries.. Before you remove the SRS harness, disconnect the
driver's airbag connector. the front passenger's
airbag connector, both side airbag connectors, both
seat belt buckle tensioner connectors, and both seat
belt tensioner connectors.. Make sure the battery is sufficiently charged. lf the
battery is dead or low, measuring values won't be
correct.. Do not touch a tester probe to the terminals in the
SRS unit or harness connectors, and do not connect
the terminals with a jumper wire. Use only the
backprobe set and the Honda PGM Tester. Backprobe
spring loaded lock type connectors correctly.
Reading the DTC
When the SRS indicator is on, read the DTC using either
of the following methods:
PGM Tester "SRS" Menu Method:
Connect the Honda PGM Tester {A) to the 16P data link
connector {DLC)(B), and follow the Tester's Drompts in
the "SRS" menu.
lf the Tester indicates no DTC, no communication. DTC
3-6 to 3-'10, DTC 4-6 to 4-10, DTC 9-1, or DTC 9-2,
double-check by using the "SCS" menu method.
