37A-10STEERING - Service Adjustment Procedures
BLEEDINGM37FKAl
1.Jack up the front wheels and support them by using a floor
stand.
2. Manually turn the oil pump pulley a few times.
3. Turn the steering wheel all the way to the left and to the
right several times.
4. Disconnect the high-tension cable, and then, while operat-
ing the starting motor intermittently, turn the steering
wheel all the way to the left and right several times (for 15
to 20 seconds).
Caution1. During air bleeding, replenish the fluid supply so
that the level never falls below the lower position ofthe filter.
2. If air bleeding is done while engine is running, the
air will be broken up and absorbed into the fluid; besure to do the bleeding only while cranking.
5. Connect the ignition cable, and then start the engine
(idling).
6.Turn the steering wheel to the left and right until there are
no air bubbles in the oil reservoir.
7.Confirm that the fluid is not milky, and that the level is up to
the specified position on the level gauge.
8. Confirm that there is very little change in the fluid level
when the steering wheel is turned left and right.
Fluid level change:wlthln 5 mm 1.2 in.)I
9.Check whether or not the change in the fluid level is within
5 mm
(.2 in.) when the engine is stopped and when it is
Irunning.
Caution
While enginerunningWhile enginestopped13UOl1. If the change of the fluid level is 5 mm
I.2 in.) or
more, the air has not been completely bled from thesystem, and thus must be bled completely.
2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be
abnormal noises from the pump and the flow-
control valve, and this condition could cause a
lessening of the life of the pump, etc.

16LOO9'(3) Insert ROM pack into the Multi-use Tester and connect
tester to Diagnosis Check Connector in glove compart-
ment.
(4) Reconnect negative terminal of battery, and turn the
ignition key to the “ON” position.
(5) Conduct self-diagnosis using Multi-use Tester to ensure
entire SRS operates properly, except open circuit of air bag
module (“22. SQUIB TRBL 2”). (Refer to
P.52B-18.)(6) Turn the ignition key to the “LOCK” position, disconnect
the negative battery cable and tape the terminal.
Caution
Wait at least 30 seconds after disconnecting the battery
cable before doing any further work. The SRS system is
designed to retain enough voltage to deploy the air bagfor a short time even after the battery has been
disconnected, so serious injury may result from unin-
tended air bag deployment if work is done on the SRSsystem immediately after the battery cable is discon-
nected.
11. INSTALLATION OF CLOCK SPRINGAlign the mating mark and “NEUTRAL” position indicator of
the clock spring, and, after turning the front wheels to the
straight-ahead position,install the clock spring to the
column switch.
CautionIf the clock spring’s mating mark, is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal
operation of the SRS and possibly leading to serious
injury to the vehicle’s driver.
9. CLOCK SPRING AND SRS DIAGNOSIS UNIT CONNEC-
TIONAfter securely and correctly installing the clock spring’s
connector to the SRS diagnosis unit, be absolutely sure to
press down the lock lever of the SRS diagnosis unit.
13R072113R072;8. INSTALLATION OF STEERING WHEEL
(1) Before installing the steering wheel, be sure to first turn
the vehicle’s front wheels to the straight-ahead position
and align the mating mark and “NEUTRAL” position
indicator of the clock spring.
Caution
Be sure when installing the steering wheel, that the
harness of the clock spring does not become caughtor tangled.
(2) After clamping, turn the steering wheel all the way in
both directions to confirm that steering is normal.
