lf deflection is not within specs' loosen the locknut'
turn the adjusting nut untilthe deflection is as speci-
fied, then retighten the locknut.
With the cable properly adiusted, check the thronle
valve to be sure it opens fully when you push the
accelerator pedal to the floor. Also check the throt-
tle valve to be sure it returns to the idle position
whenever you release the accelerator pedal'

1. Open the throttle valve fully, then install the throttle
cable in the throttle linkage, and install the cable
housing in the cable bracket.

LOCKNUT
Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or neutral) until the radiator fan
comes on, then let it idle.
Hold the cable sheath. removing all slack from the

4. Measure the clearance between the 2nd gear andthe 28 mm distance collar with a feeler gauge.
NOTE: Take measurements in at least three places.and use the average as the actuar ctearance.
STANDAFD: 0.10 - 0.18 mm {0.004 - 0.002 inl
lf the clearance is out of tolerance. remove the 2gmm distance collar and measure the width.
Select and install a new distance collar, thenrecheck.

Retractor InsDection
Before installing the retractor, check that the seat belt
can be pulled out freely.
Make sure that the seat belt does not lock when the
retractor is leaned slowly up to 15'from the mounted
position. The seat belt should lock when the retractor
is leaned over 40'.
CAUTION: Do not attempt to disassemble the retrac-
tor.

Check that the seat belt is not twisted or caught on
anyrn I ng.
After installing the anchors, check for free move
ment on the anchor bolts. lf necessary, remove the
anchor bolts and check that the washers and other
parts are not damaged or improperly installed
Check the seat belts for damage or discoloration.
Clean with a shop towel il necessary
CAUTION: Use only soap and water to clean.
NOTE: Dirt build-up in the metal loops of the upper
anchors can cause the seat belts to retract slowly.
Wipe the inside ot the loops with a clean cloth damF
ened in isopropyl alcohol.
Check that the seat belt does not lock when pulled
out slowly. The seat belt is designed to lock only
during a sudden stop or impact.
Make sure that the seat belt will retract automatically
when released.
For each passenger's seat belt, make sure that the
locking mechanism in the seat belt retractor will
engage when the seat belt is pulled all the way out.
Replace the seat belt with a new one il there is any
abnormality.

Troubleshooting

NOTE:* 1: In case of an intermittent failure DTC 9-1, it means there was an internal failure of the SRS unit or a faulty SRS indica-
tor light circuit. Do the troubleshooting for intermittent failures (page 24-'15).*2: In case of an intermittent failure DTC 9-2, it means there was an internal failure of the power supply {VB line). Do the
troubleshooting for intermiftent failures.*3: DTC cannot be read with a Honda PGM Tester; check by jumping the SCS service connector.
