Battery
a Battery fluid (electrolytel contains sulfuric acid. lt may causo severe burns if it gsts on yout skin or in your eyes.Wear piotective clothing and a face shield.- ll electrolyte gets on your skin or clothes, rinse it ofl with water immediately.- lf electlolyte gets in your eyes, tlush it out by splashing water in your eyes for at least 15 minutes; call a physicianimmediately.
a A battery gives off hydlogen gas. lf ignited, the hydrogen will explode and could crack the battery case and splatte.acid on you. K6ep sparks, flames, and cigarettes away from the battery.a Overchalging will raisc the temperatulg of the electrolyte. This may force electrolyte to spray out ol the battery vents.Follow the chatge. manutacturer's instructions and charge the baftely at a ptope. rate.
NOTE: The original radio has a coded theft protection circuit. lf service to the car requires any of the tollowing, be sureto get the customer's code number before- disconnecting the battery.- removing No. 47 (7.5 A) fuse from the under-hood fuse/relay box.- removing the radio.
After service, reconnect power to the radio and turn it on. When the word "CODE" is displayed, enter tne customer's5-digit code to restore radio operation,
Use either a JCI or Bear ARBST tester, and follow the manufacturer's procedures. lf you don't have one of these com-puterazed testers, follow this conventional test Drocedure:To get accurate results, the temperature of the electrolyte must be between 70'F {21oC} and IOOoF (38oC).
lf the case is cracked or the posts are loose,
reDlace the batterv.
lf the indicator shows low electrolyte, add
distilled water if possible.
Test Load Capacity (# 1l
. Apply 3O0 amp load for 15 seconds to remove
surface charge.. Allow 15 seconds recovery period.. Apply test load {see Test Load Chart).. Record voltage at the end of l5 seconds.
Voltage stays above 9.6
volts: The battery is OK.

'\' '\, ili \.-.-1 i^\\,,; i \
The SRS is a safetv device which, when used in coniunction with the seat belt, is designed to help protect the driver and
front passenger in a frontal impact exceeding a cenain set limit. The system consists ot the SRS unit (including safing sen-
sor and imDact sensor), the cable reel, the driver's airbag, and front passenger's airbag
Operation t'Its
The main circuit in the SRS unit senses and judges the force ot impact and, il necessary, ignites the inflator charges. If bat-
tery voltage is too low or power is disconnected due to the impact, the back-up power circuii will keep voltage at a con-
stant level.
For the SRS to operate:
(1) The impact sensor and safing sensor must activate and send electric signals to lhe mictop.Goi
{2) The microprocessor must compute the signals and send signals to the airbag inflators'
(3) The inflators must ignite and deploy the airbags sE Lr.r

Self-diagnosis System
A self-diagnosis circuit is built into the sRs unit; when the ignition switch is turned oN (ll), the sRS indicator light comes
on and goes off after about six seconds if the system is operating normally'
lf the light does not come on, or does not go off after six seconds, or if it comes on while driving. it indicates an abnormal-
ity in the system. The system must be inspected and repaired as soon as possible'
For better servicesbility. the memory will store the cause of the malfunction, and the data link circuit passes on the infor-
mation from the memory to the data link connector (DLC). This information can be read with the Honda PGM Tester con-
nected to the DLc (16P).

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
SRS unit; the airbags could accidentally deploy and cause damage or injuries'
. Before you remove the SRS main harness, disconnect the driver's airbag connector
conneclor.
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-

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.
