3. Vehicle involved in collision and airbag is deployed:
INSPECT SUPPLEMENTAL RESTRAINT SYSTEM
(a) Do a diagnostic system check (See page DI-349).
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check the deformation of the steering wheel.
Check the damage on the spiral cable connector
and wire harness.
HINT:
There should be no interference between the steering wheel
pad and steering wheel, and the clearance should be uniform
all the way around when the new steering wheel pad is installed
on the steering wheel.
CAUTION:
For removal and installation of the steering wheel pad, see
page SR-12 and SR-22, and be sure to follow the correct
procedure.

BLEEDING
1. CHECK FLUID LEVEL (See page SR-5)
2. JACK UP FRONT OF VEHICLE AND SUPPORT IT
WITH STANDS
3. TURN STEERING WHEEL
With the engine stopped, turn the steering wheel slowly from
lock to lock several times.
4. LOWER VEHICLE
5. START ENGINE
Run the engine at idle for a few minutes.
6. TURN STEERING WHEEL
(a) With the engine idling, turn the steering wheel to left or
right full lock position and keep it there for 2-3 seconds,
then turn the steering wheel to the opposite full lock posi-
tion and keep it there for 2-3 seconds.
(b) Repeat (a) several times.
7. STOP ENGINE
8. CHECK FOR FOAMING OR EMULSIFICATION
If the system has to be bled twice specifically because of foam-
ing or emulsification, check for fluid leaks in the system.
9. CHECK FLUID LEVEL (See page SR-5)

INSPECTION
1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil
reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON® II or III
HINT:
Check that the fluid level is within the HOT LEVEL range on the
reservoir. If the fluid is cold, check that it is within the COLD
LEVEL range.
(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80°C (176°F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed power steering sys-
tem (See page SR-4).
(f) With the engine idling, measure the fluid level in the oil
reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the oil
reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed power steering system (See page
SR-4).
(i) Check the fluid level.

2. CHECK STEERING FLUID PRESSURE
(a) Disconnect the pressure feed tube (See page SR-27).
(b) Connect SST to pressure feed tubes, as shown in the il-
lustration below.
SST 09640- 10010 (09641- 01010, 09641- 01030,
09641-01060)
NOTICE:
Check that the valve of the SST is in the open position.
(c) Bleed the power steering system (See page SR-4).
(d) Start the engine and run it at idle.
(e) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80 °C (176 °F)
(f) With the engine idling, close the valve of the SST and ob-
serve the reading on the SST.
Minimum fluid pressure:
7,845 kPa (80 kgf/cm
2, 1,138 psi)
NOTICE:
Do not keep the valve closed for more than 10 se-
conds.
Do not let the fluid temperature become too high.
