SUPPLEN\EN AL RES\RA(N SYSTES{ (SRS\
This model has an SRS which includes a driver's airbag in the steering wheel hub. a passenger's airbag in the dashboardabove the glove box ('97 - 00 models), and seat belt tensioners in the seat belt retractors ('98 - 00 models). Informationnecessary to safely service the SRS is included in this Service Manual. ltems marked with an asterisk (*) on the contentspage include, or are located near, SBS components. Servicing. disassembling or replacing these items will require specialprecautions and tools, and should only be done by an authorized Honda oearer.
To avoid rendering the SRS inoperative, which could lead to peFonal iniury or death in the event of a sevore trontalcollision. allSRS service work must be performod by an authorized Honda dealer.lmproper service procedurgs, including incorrect removal and installalion of the SRS, could lead to personal iniurycaused by unintontional deployment of th€ airbags {'97 - 00 models), and seat belt tensioners ('98 - 00 modelsl.Do not bump the SRS unit. Otherwise, the system may lail in case ot a collision, or the airbags may deploy when theignition switch is ON (lll.
SRS electrical wiring harnesses are identitied by yellow colof coding. Ralated components are located in the steeringcolumn, front console, dashboard, dashboard lower panel, and in the dashboard above the glove box. Do not use elec-trical test equipment on these cilcuits,

Note these items during disassembly:' lf an intact airbag assembly has been removed from a scrapped vehicle or has been found defective or damaged dur-ing transit, storage or service. it should be deployed (see section 24),a Before removing the gearbox, remove the driver.s airbag assembly and steering wheel.. After installing the gearbox, check the wheel alignment and adjust if necessary.
SRS components are located in this area. Review the SRS component locations, precautions, and procedures an the SRssection (24) before performing repairs or servrce.

Troubleshooting
General Troubleshootin g
Check the following before you begin:
. Has the suspension been modified in a way that would affect steering?
. Are tire sizes, tire variety and air pressure correct?
. ls the steering wheel original equipment or equivalent?
. ls the power steering pump belt properly adjusted?
. ls steering fluid reservoir filled to proper level?
. ls the engine idle speed correct and steady?
Hard Steering (Check the power assist, see page 17-12. lf the force is over 29 N (3.0 kgl 6.6 lbfl, proceed with this troubleshooting.i
Abnormalthiidpressure (Iluidpressure is toohigh)

Check the teed and return circuit lines and hosebetween the gearbox and pump for clogging anddeformation.
Normal line and hose
Check the pump fluid pressure(see page 17-16 or 17-17).Measure steady state lluid pres-
sure at idle with the pressure con-trol valve and the shut-off valve (it
so equipped) fully open.The fluid pressure should be 1,500kPa (15 kgf/cm,,213 psi)or less.
Normal
Check the flow control valve (see page 17 26).. Check the valv€ lor smooth movement in the hous-ing.. Check the relief valve for leaks.
Check the pump fluid pressure(see page 17-16 or l7-17).Measure pump relief pressure atidle with the pressure controlvalve and the shut'off valve lil soequipped) fully closed.The fluid pressure should be 6,9007,800 kPa (70 - 80 kgflcm,, 1,000- 1,140 psi).

Shock or vibration when wheel isturned to full lock.
Steering wheel will not returnsmoothly.
lf the problem is not corrected byadjusting the rack guide, adjustthe front wheel alignment (see
section 18).
Check the rack guide for proper

Check the rack guide for properadjustment (see page 17'15).
Adjust the rack guide.
Rack guide is adiusted properly.
lf the problem is not corrected byadjusting the rack guide, replacethe gearbox.Check the belt for slippage andadjust as necessary (see page 17-14).
A and B cylinder lines are normal, check wheel alignment (see

Check power steering lluid level. lfthe level is excessively low checkfor leaks in the system. Add fluidto the specified level.
Air in reservoir, or check powersteering tluid level.
lf fluid level is OK, check O-ringsand seals on both ends of thepump inlet hose, and the P/Spump housing mating surlacesand drive shaft oil seal for suction leaks. Check the reservoir forcracks, Replace parts as neces-
Pump belt slipping on pulley(pump stops momentarily).Adjust the belt tension (see page17-14) or replace belt.
Check if pump pressure is normaland the gauge needle travel is 500kPa (5 kgl/cm,, 71 psi) or less.Check the flow control valve if theneedle travel exceeds 500 kPa (5kgflcm', 71 psi). lI the flow controlvalve is normal, replace the pumpas an assembly,
Install the power steering pres-sure gauge, Close the pressurecontrol valve and shut off valve (if
so equipped) fully and measurethe pump pressure (see page 17-16ot 17 17).

Troubleshooting
Noise and Vibration
NOTE: Pump noise in first 2 - 3 minutes after starting in cold weather is normal.
Humming
Rattle or chattering
Humming due to pulsation of fluid is normal, particularly when the wheel isturned with the vehicle stooDed.
lf equipped with automatic trans-mission, the hum could be thetorque converter or pump noase.
Confirm by temporarily removingthe pump belt.
Feed hose (high-pressure) touch-ing the frame.Beposition the feed hose.
Loose steering shaft connector,tie-rod, or balljoint.Check and tighten, or replaceparts as necessary,
Column shaft wobbling.Roplace the column assembly.
Check the rack guide for properadjustment (see page 17-15).Adjust, if necessary.
Rattling sound and feeling when turning the steering wheel right and left with th€engine OFF is normal.
Pump noise, though not loud, from the valve body unit can be heard when turn-ing the steering wheel to full lock in either direction. This is normal. Do not holdthe steering wheel at full lock lor more than five seconds when inspecting.

Inspection and Adjustment
Steering Operation
Place the front wheels in the straight ahead position.
and measure the distance the steering wheel can be
turned without moving the front wheels.
ROTATIONAL PLAY: 0 - 10 mm (0 - 0.39 inl
lf the play exceeds the limit, perform rack guide adjust-
ment (see page 17-15).
lf the play is still excessive after rack guide adjustment,
inspect the steering linkage and gearbox as described
on the next page.

Power Assist Check with
Vehicle Parked
1. Check the power steering fluid level (see page 17-
15) and pump belt tension (see page 17-14).
2. Start the engine, allow it to idle, and turn the steer-
ing wheel from lock-toiock several times to warm
up the fluid.
3. Aftach a spring scale to the steering wheel, With the
engine idling and the vehicle on a clean. dry floor,
pull the scale as shown and read it as soon as the
tires begin to turn.
SPRINGSCALE(Commercially
available)
The scale should read no more than 29 N (3.0 kgf,
6.6 lbfl. lf it reads more, check the gearbox and
oumo.
