)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
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-
onds after the SRS indicator light went otf.
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
comes on,
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.
t*F
ON
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.
-+t 6!.c l.-
Problem recurs, light stays on.
6. lf you can't duplicate the intermiftent tailure, the sys-
tem is OK at this time.
