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.

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.

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.
