Wiring Precautions
. Never attempt to modify, splice or repair SRS wiring.
NOTE: SRS wiring can be identified by special yellow
outer protective covering.
. Be sure to install ihe harness wires so that they are not
pinched or interfering with other car parts.
. Make sure all SRS ground locations are clean and
grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.
Backprobing Spring-loaded Lock
Connectors
. When checking voltage or resistance on this type of
connector the first time, it is necessary to remove the
retainer to insert tester probes from the wire side.
NOTE: lt is not necessary to reinstall the removed
retainer; the terminals will stav locked in the connec-
tor housing.
To remove the retainer, insen a flat tip scrGirdr'\/".
between connector body and retainer, and car"fully
ory out the retarner.
NOTE: Take care not to break the conn€ctor.

with Built-in Short Contact
The driver's and front passenger's airbag have a spring-
loaded lock connector with a built-in short contact.
When this connector is disconnected, the power termi-
nal and the ground terminal in the airbag connector are
automatically shorted.

Steering-related Precautions
Steering Wheel and Gable Reel Alignment
NOTE: To avoid misalignment of the steering wheel or
airbag on reassembly. make sure the wheels are turned
straight ahead before removing the steering wheel.
Rotate the cable reel clockwise unit it stops.
Then rotate it counterclockwise (approximately two and a
half turns) until the arrow mark on the cable reel label
points straight up.

Steering Column Removal
CAUTION:
. Before romoving the steoring column, lirst di3con-
nect ths connector bctwoen tho csble rsal and the
SBS main harneEs.
. lf the steeting column is going to be rsmoved with-
out dismounting the steering wheel, lock the steer-
ing by iurning the ignition k6y to o'LOCK position' or
remove tho key lrom thc ignition ro that the steering
wheel will not turn.
NOTE:
When the airbag and cable reel 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 connec-
tor, refer to page 23-284,
SRS MAIN HARNESS2P CONNECTOR
Do not replace the original steering wheel with any other
design since it will make it impossible to properly install
the airbag {only use genuine Honda replacement parts).
After reassembly. confirm that 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 wheel.

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

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.

CAUTION:
. Before installing the steering wheel, the lront
wheels should be aligned str8ight ahead.
. Be sure to install the harness wires so that they
are not pinched or interfering with other parts.
. After reassembly, confirm thal the wheels are
slill turned str8ight ahead and that the steering

spoke angle adjustment is necessary, do so only
by adiusting the tie-.ods, not by removing and

Power Distribution Schematics
From Fuses to Relays and Components
The second half of Power Distribution shows the wiring "From Fuses to Relays and
Components." This can speed your troubleshooting by showing which circuits share fuses. lf
Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a
component in the other circuit. lf it works, you know the fuse is good and power is available to
the inooerative circuil.
