Precautions/Procedures
Disconneeting the Airbag Connectors and the Seat Belt Tensioner
Connectors (cont'd)
1.Disconnect the battery negative cable, then discon-
nect the positive cable from the battery. and wait at
least three minutes.
Disconnect the airbag and tensioner connectors
lsee page 24-22).
Driver's Airbag:
. Remove the access panel from the steering
wheel, then disconnect the 2P connector
between the driver's airbag and cable reel. When
disconnected, the airbag connector is automati-
callv shorted.

ACCESS PANEL
Seat Bslt Tensioner (38 - 00 modebl:
. Remove the left and (or) right center pillar lower
trim panels (see section 20).
. Disconnect the seat belt tensioner 2P connectors
from the left side wire harness (driver's side) and

)Steering-related Precautions
Stooring Wh€el and Csble Re6l Alignm€nt
To avoid misalignment of the steering wheel on
reassembly, make sure the wheels are turned straight
ahead beJore removing the steering wheel.
To center the cable reel, rotate the cable reel clockwise
until it stops, Then rotate it counterclockwise (approxi-
mately two and a half turns) until the arrow mark on the
cable reel label points straight up.
Steering Column Bemoval
CAUTION: Before removing the stosring column, tirsi
disconneqt tha connsctor between tho cabls roel and
the SRS main harness.
lf the steering column is going to be removed without
dismounting the steering wheel, lock the sieering by
turning the ignition key to o-LOCK position, or remove
the key trom the ignition so that the steering wheel will
not turn.
LABEL
NOTE:
. When the airbag and cable r6el are disconnected, and
the battery is reconnected and the ignition switch is
turned ON (ll), the SRS unit will store this as an open
in the driver's airbag inflator, and the SRS indicator
light will come on, In such a case, make sure to con-
firm the DTC, then clear the SRS unit memory.
. For disconnecting the spring-loaded lock type con-
nector, refer to page 24-22.

Do not replace the original steering wheel with any other
design because it will make it impossible to properly
install the airbag (use only genuine Honda replacement
partsl.
After reassemblv, confirm the wheels are still turned
straight ahead and that the steering wheel spoke angle
is correct. lf minor spoke angle adjustment is necessary,
do so only by adjusting the tie-rods, not by removing
and repositioning the steering whee .

Troubleshooting
Self-diagnostic Procedures
The self-diagnostic function of the SRS system allows it to locate the causes of system problems and to store this informa-
tion 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 six seconds, the system is
normal.
. lf there is 8n abnormality, the system locates and defines the problem. stores this information in memory, and turns
the SRS indicator light on. The data will remain in the memory even when the ignition switch is turned off or if the bat-
terv is disconnected.
. When you connect the SCS service connector to the service check connector (2P), and turn the ignition switch ON (ll),
the SRS indicator light will indicate the diagnostic trouble code (DTC) by the number of blinks.
. After reading and recording the DTC, proceed with the troubleshooting forthis code.
Precsutions
. Use only a digital multimeter to check the system. lf it's not a Honda multimeter. make sure its output is 10 mA (0.01 A)
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 isON (ll). or has been turned OFF for less than three minutes, be careful nottobumpthe
SRS unit; the airbags could accidentally deploy and cause damage or injuries.
. Before you remove the SRS main harness, disconnect the airbag and tensioner connectors (see page 24-23).
. Make sure the battery is sufficiently charged (see section 23). 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 SCS service connector.
For backprobing spring-loaded lock type con nectors, .efet to page 24-22.
Reading the DTC
When the SRS indicator light is on, read the DTC using one of these methods;
A. Connect the Honda PGM Tester to the 16P Data Link Connector {DLC), and follow the tester's prompts. lf the tester
indicates no DTC, DTC 9-1 and DTC 9-2, double-check by jumping the service check connector (2P) and watching the
SRS indicator light (see next page).

)
B.The SRS indicator light can also indicate the DTC by the number oJ blinks when the SCS service connector is connecr-ed to the service check connector (2P).
Turn the ignition switch OFF, and wait for ten seconds. Then connect the SCS service connector to the service checkconnector {2P). lf you do not wait ten seconds. the SRS unit will not be completely reset and will not output DTCS.

2. Turn the ignition switch ON (ll). The SRS indicator light comes on for about six seconds and then goes off. Then it willindicate the DTC:- The DTC consists of a main code and a sub-code.- Including the most recent problem, up to three different malfunctions can be indicated.- In case of a continuous failure. the DTC will be indicated repeatedly (see example 1 below).- In case of an intermittent failure, the SRS indicator light will indicate the DTC one time, then it will stay on (see exarn-pte 2 below).- lf both a continuous and an intermittent failure occur, both DTCS will be indicated as continuous failures.- In case the system is normal {no DTC), the SRS indicator light will stay on (see example 3).3. Read the DTC.
4. Turn the ignition switch OFF. and wait for ten seconds. Then disconnect the SCS service connector Jrom the servicecheck connector (2P).

Troubleshooting
Erasing the DTC Memory
To erase the DTC{S) from the SRS unit, use a Honda
PGM Tester (see the Honda PGM Tester SRS Vehicle
System Supplement) or the following procedure.
1. Make sure the ignition switch is OFF.
2. Connect the SCS service connector to the MES con,
nector (2P). Do not use a jumper wire.

3. Turn the ignition switch ON (ll),
4. The SRS indicator light comes on for about six sec-
onds and then goes off. Remove the SCS servjce con
nector from the MES connector {2P) within four sec-

5. The SRS indicator light comes on again. Reconnect
the SCS service connector to the MES connector(2P) within four seconds after the SRS indicator lioht

6. The SRS indicator light goes otf. Remove the SCS
service connector from the MES connector (2P)
within four seconds.
7. The SRS indicator light indicates that the memory is
erased by blinking two times.

Troubleshooting Intermittent
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 light comes on.
After checking the DTC, troubleshoot as follows:
1. Read the DTC (see "Reading the DTC").
4.
Erase the DTC memory (see "Erasing the DTC
Memory").
With the shift lever in neutral, turn the ignition switch
ON (ll), and let the engine idle.
The SRS indicator ljght comes on for about six sec-
onds and then goes off.

lt--- _l
Shake the wire harness and the connector, take a test
drive (quick acceleration, quick braking, cornering),
and turn the steering wheel fully left and right, and
hold it there for five to ten seconds to find the cause
of the intermittent failure.
lf the problem recurs, the SRS indicator light will
stay on.

Problem recurs, light stays on.
6. lf you can't duplicate the intermiftent tailure, the sys-
tem is OK at this time.
