B. The SRS indicator light can also indicate the DTC by the number of blinks when the SCS service connector is connect-ed to the service check connector (2P).
1. 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 goes off. Then it will indi,cate 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 exam-ple 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 from the servicecheck connector (2P).

)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 wlre.

Turn the ignition switch ON (ll).
The SRS indicator light comes on for about six sec-
onds and goes off. Remove the SCS service connec-
tor from the MES connector (2P) within four seconds
after the SRS indicator light went off.
The SRS indicator light comes on again. Reconnect
the SCS service connector to the lvlES connector
(2P) within the four seconds after the SRS indicator
light comes on.
The SRS indicator light goes off. Remove the SCS
service connector from the MES connector (2P)
within four seconds.
The SRS indicator light indicates that the memory is
erased by blinking two times.
Turn the ignition switch OFF, and wait for ten sec-
onos.

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.
Afte. checking the DTC, troubleshoot as lollows:
1. Read rhe DTC {see "Reading the DTC"}.
Erase the DTC memory (see "Erasing the DTC
Memory").
With the shifi lever in neutral, turn the ignition switch
ON (ll), and lei the engine idle.
The SRS indicator light comes on for about six sec-
onds and goes off.

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 lo ten seconds to find the cause
of the intermittent failure.
lf the problem recurs, the SRS indicator light will
stay on.
