Hydraulic Pressure In P/S Circuit Check
1) Clean where pipe is connected thoroughly, then disconnect
high pressure hose from high pressure pipe connector and
connect oil pressure gauge (special tool) as shown.
Special tool
(A) : 09915-77410
(B) : 09915-77420
2) Bleed air.
3) With engine running at idling speed, keep turning steering

warmed to 50 to 60 °C (122 – 140 °F)
4) Back pressure check
With engine running at idling speed and hands off from
steering wheel, check hydraulic pressure.
If back pressure exceeds 980 kPa (10 kg/cm
2, 142 psi),
check control valve and pipes for obstruction.

Drive Air Bag (Inflator) Module (For Vehicle
with Air Bag System)
REMOVAL
1) Disconnect negative battery cable at battery terminal.
2) Disable air bag system. Refer to “Disabling Air Bag System”
in Section 10B.
3) Remove steering wheel side cap (1) of left side.
4) Loosen 2 bolts (2) mounting driver air bag (inflator) module
till it turns freely, pull them out and fix them to bolt clamps (3).
5) Remove driver air bag (inflator) module (1) from steering
wheel.

INSPECTION
WARNING:
When handling an air bag (inflator) module, be sure to
read “Service Precautions” given earlier in this section
and observe each instruction. Failure to follow them
could cause a damage to the air bag (inflator) module or
result in personal injury.
WARNING:
Never disassemble driver air bag (inflator) module or
measure its resistance. Otherwise, personal injury may
result.
CAUTION:
If air bag (inflator) module was dropped from a height of
90 cm (3 ft) or more, it should be replaced.

Steering Wheel
2. Inflator case
CAUTION:
For vehicle with air bag system
Removal of the steering wheel allows the contact coil to
turn freely but do not turn the contact coil (on the combi-
nation switch) more than allowable number of turns
(about two and a half turns from the center position
clockwise or counterclockwise respectively), or coil will
break.
