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.

General Troubleshooting Information (cont'dl
Erasing the DTG Memory
Specisl Tool Required
SCS service connector 07PAz-0010100
To erase the DTC(S)from the SRS unit, use a Honda
PGM Tester {see lhe Honda PGfM Tester SRS Vehicle
System Supplement) or the following procedure.
1. Make sure the ignition switch is OFF.
2. Connect the SCS service connector {A) to the MES
2P connector (B). Do not use a jumper wire.
07PAZ-0010100
3. Turn the ignition switch ON (ll).
4. The SRS indicator will come on for about 6 seconds,
and then go off. Remove the SCS service connector
from the MES connector within 4 seconds after the
indicator goes off.
5. The SRS indicator will come on again. Reconnect
the SCS service connector to the MES connector
within 4 seconds after the indicator comes on.
6. When the SRS indicator goes off, remove the SCS
service connector from the MES connector within 4
seconds.
7. The SRS indicator will bllnk two times indicating
that the memory has been erased.
8. Turn the ignition switch OFF, and wait for '10
seconds.
9. Turn the ignition switch ON (ll) again. The SRS js
OK if the SRS indicator comes on for 6 seconds and
then goes off.

Troubleshooting lntermittent Failures
lf there was a malfunction, but it doesn't recur. it will be
stored in the memory as an intermittent failure, and the
SRS indicator will come on.
After checking the DTC, troubleshoot as follows:
1. Read the DTC (see "Reading the DTC").
2. Erase the DTC memory (see "Erasing the DTC
Memory").
3. With the shift lever in neutral, start the engine, and
let it idle.
The SRS indicator will come on for about 6 seconds
and then go off.
Shake the wire harness and the connectors. take a
test drive (quick acceleration, quick braking,
cornering), turn the steering wheel fully left and
right, and hold it there for 5 to '10 seconds. lf the
problem recurs, the SRS indicator will come on.
lf you can't duplicate the intermittent failure, the
system is OK at this time.

Airbag Disposal
Special Tool Required
Deployment tool 07HAz-SG00500
Before scrapping any airbags, side airbags, seat belt
tensioners, or seat belt buckle tensioners (including
those in a whole vehicle to be scrapped), the airbags,
side airbags, seat belt tensioners, or seat belt buckle
tensioners must be deployed. lf the vehicle is still within
the warranty period, the Honda District Service
Manager must give approval and/or special instruction
before deploying the airbags, side airbags, seat belt
tensioners, or seat belt buckle tensioners. Only after the
airbags, side airbags, seat belt tensioners, or seat belt
buckle tensioners have been deployed (as the result of
vehicle collision, for example), can they be scrapped.
lf the airbags, side airbags, seat belt tensioners, and
seat belt buckle tensioners appear intact (not deployed),
treat them with extreme caution. Follow this Drocedure.
Deploying Airbags in the Vehicle
lf an SRS equipped vehicle is to be entirely scrapped, its
airbags, side airbags. seat belt tensioners. and seat belt
buckle tensioners should be deoloved while still in the
vehicle. The airbags, side airbags, seat belttensioners,
and seat belt buckle tensioners should not be
considered as salvageable parts and should never be
installed in another vehicle.
1. Turn the ignition switch OFF, then disconnect the
battery negative cable, and wait at least 3 minutes.
2. Confirm that each airbag, side airbag, or seat belt
tensioner is securely mounted.
3. Conf irm that the specia I tool isfunctioning properly
by following the check procedure on the tool label.
