Wiring Precautions
. Never attempt to modify, splice or repair SRS wiring'
NOTE: SRS wiring can be identified by special yellow
outer Protective covering.
8e sure to install the harness wires so that they are not
oinched or interfering with other parts.
t
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
Gonnectors
. When checking voltage or resistance on this type of
connector the flrst time, it is necessary to remove lne
retainer to insert tester probes from the wire side.
NOTE: lt is not necessary to reinstall the removed
retainer; the terminals wi I stay locked in the connec-
tor housrng.
To remove the retainer, insert a flat tip screwdriver
between connector body and retainer, and carefully
pry out the retainer.
NOTE: Take care not to break the connector.

Preca utions/Procedures
Spring-loaded Lock Connector
Some SRS system connectors have a spring-loaded lock.
Disconnecting
To release the lock, pull the spring-loaded sleeve towardthe stop while holding the opposite half of the connecror.Then pull the connector halves apart.
NOTE: Be sure to pull
connector half.
on the sleeve and not on the
SPRING-LOADEOSLEEVE
Do not pull on thishalf of the connector.
Connecting
1. Hold the pawl-side connector half, and press on theback of the sleeve-side connector half in the directionshown. As the two connector halves are pressed
together, the sleeve is pushed back by the pawl.
NOTE: Do not touch the sleeve.
When the connector halves are completely connected,the pawl is released, and the spring-loaded sleevelocks the connector.SPRING.LOADEDSLEEVE

Spring-loaded Lock Connector with
Built-in Short Contact
The driver's ajrbag (and front passenger,s) airbag has(have) a spring-loaded lock connector with a builr-inshort contact. When this connector is disconnected, thepower terminal and the ground terminal in the airbaaconnector are automatically shoned.

Precautions/Procedu res
Steering-related Precautions
Stesring Wheel and Cable Reol Alignment
NOTE: To avoid misalignment of the steering wheel on
reassembly, make sure the wheels are turned straight
ahead before removing the steering wheel.
Rotate the cable reel clockwise until it stops.
Then rotate it counterclockwise {approximately two and
a half turns) until the arrow mark on the cable reel label
points straight up.

St€€rin9 Column Removal
CAUTION:
. Eefore removing thg stggring column. disconnect the
connsstor bqtween the cable r€el and th€ SRS msin
harness.
. lf the stoering column is going to be romoved with-
out dismounting th6 stoering wheel, lock the steer-
ing by turning the ignition key to o-LOCK position, or
remove the key trom the ignition switch so that the
steering wheel will not turn.
NOTE:
When the airbag and cable reel are disconnected,
don't reconnect the battery cable. lf 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.
For disconnecting the spring-loaded lock type con-
nector, refer to page 24-'10.
SRS MAIN HARNESS2P CONNECTOR
Do not replace the original steering wheel with any other
design because it will make it impossible to properly
install the airbag (only use genuine Honda replacement
parts).
After reassembly, confirm 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' I
tion in memory. For easier troubleshooting, this data can be retrieved via a data link circuit l
. When you turn the ignition switch ON (ll), the SRS indicator will come on. ll it goes off after six seconds. the system is
norma l.
. lf there is an abnormality, the system locates and defines the problem, stores this information in memory, and turns
the sRS indicator light on. The data will remain in the memory even when the ignition switch is turned off or if the bat-
tery is disconnected.
o when you connect the scs service connector to the service check connector (2P), and turn the ignition switch oN (ll),

. Before you ,"n1ou" th" SRS main harness, disconnect the driver's airbag connector (and the front passenger's airbag
connector).
. Make sure the battery is sufficiently charged {see section 23}. lf the battery is dead or low, measuring valLles won t be
correct.
. 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 or the special tools'
For backprobing spring-loaded lock type connectors, refer to page 24-9'
Reading the DTC
when the SRS indicator light is on, read the DTC using one of these methods:
A. Connect the Honda PGM Tester to the 16P Data Link Connector {DLC), and follow the tester's prompts lf the tester

11.
NOTE:
. Before installing the steering wheel, the front
wheels should be aligned straight ahead.. Be sure to install the harness wires so that theyare not pinched or interfering with other parts.. After reassembly. confirm that the wheels arestill turned straight ahead and that the steeringwheel spoke angle is correct (road test). lf minor
spoke angle adjustment is necessary, do so onlyby adjusting the tie-rods, not by removing andrepositioning the steering wheel.
Set the cancel sleeve so that the projections arealigned venically.
PROJECTIONS
12. Carefully install the cable reel on the steering column shaft. Then connect the 3p connector to thecable reel sub-harness, and connect the 2p connec-tor to the SRS main harness.
. 24-74
Install the steering column covers.
lf necessary, center the cable reel. {New replacementcable reels come centered.) Do this by first rotating thecable reel clockwise until it stops. Then rotate tt counterclockwise (approximately two and a half turns) untilthe arrow mark on the cable reel label points straightup.

Power Distribution Schematics
Power Distribution schematics show how power is supplied from the positive battery terminal to
various circuits in the car. Refer to the Power Distribution section to get a more detailed picture
of how power is supplied to the circuit you're working on.
From Battery to lgnition Switch, Fuses, and Relays
Individual circuit schematics begin with a fuse. The first half of Power Distribution, however,
shows the wiring "upstream" between the battery and the fuses.

Switches
These switches move
together; the broken straight
line between them means the,
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted. all switches are shown
in their normal (rest) position,
with power off.
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car frame or to a metal
part connected to the frame.
This symbol represents
the bus inside a ground
connector. The dots I

The ground symbol (large dot)
is the connection between the
bus and metal (grounded) part
of the car.

Fuses
This means power is supplied

Current rating
Diodes
A rectifier diode works like a one
way valve. lt allows current to
llow only in the direction of the
arrow.
A Zener diode blocks reverse
current at normal voltages just like
a rectifier diode. At high voltages.
however, a Zener diode allows
current to f low in reverse

Each "T" lerminal (ring type)
is numbered for reference and
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interference) shielding
around a wire. The
shielding is always
connected to ground.
