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 memorv. For easier troubleshooting, this data can be retrieved via 8 dats link circuit.
o When you turn the ignition switch ON (ll), the SRS indicator will come on. lf it goes off after six seconds, the system is
normat.
. lf there is 8n abnormality, the system locstes and defines the problem, stores this information in memory, and turns
th€ 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 (DTCI by th€ number of blinks.
. After reading and recording the DTC, proceed with the troubleshooting for this code
Pr6crution!
. 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 damsge the
airbag circuit or cause sccidental airbag deployment and possible injury.
. Whenever the ignition switch is ON (ll), or has been turned OFF for less than three

. Before you remove the SRS main harness, disconnect the driver's airbag connector

and the front passenger's airbag
. Make sure the battery is sufficiently charged (s6e psge 23-67). lf the battsry is dead or low, msasuring values won't be
correct,
a 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 connectors, refer to psge 23-283.

B. The SRS indicator light can also indicate the OTC by the number of blinks when the SCS service connector ts 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 completelv reset and will not outout DTCS.SRS INDICATOR LIGHT

2. Turn the ignition swilch ON (ll). The SRS indicator light comes on for about six seconds and then goes off. Then it will
indicate 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.- ln case of a continuous failure, the DTC will be indicated repeatedly (see example 1 below).- In case of an intermiftent failure, the SRS indicator light will indicate the DTC one time. then it will stay on (see exarn-ple 2 beiow).- 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 SBS 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 MES 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.
Troubleshootin g Intermittent
Failures
lf the.e 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,
Atter chocking ths 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 l€ver in neutral, turn the ignition switch
ON (ll), and let the engine idle.
4. The SRS indicator light comes on for about six sec-
onds and then goes off.
