INSTALLATION
NOTICE:
Never use airbag parts from another vehicle. When replac-
ing parts, replace with new parts.
1. INSTALL FRONT PASSENGER AIRBAG ASSEMBLY
Install the airbag door and front passenger airbag assembly to
the instrument panel.
CAUTION:
Make sure that no foreign objects are trapped be-
tween the airbag and the module.
Do not damage the strap when installing the module.
If the airbag door is cracked or its surface is peeling,
always replace it with a new airbag door.
NOTICE:
If the front passenger airbag assembly has been dropped,
or there are cracks, dents or other defects in the case or
connector, replace the front passenger airbag assembly
with a new one.
2. INSTALL INSTRUMENT PANEL (See page BO−80)
Install the 2 bolts to instrument panel reinforcement. Torque: 20 N·m (210 kgf·cm, 15 ft·lbf)
NOTICE:
Make sure the front passenger airbag assembly is installed
to the specified torque.When installing the instrument pan-
el, take care that the airbag wire harness does not interfere
with other parts and is not pinched between other parts.

(d) Observe the following precautions when removing and
installing the injectors.
(1) Never reuse the O −ring.
(2) When placing a new O −ring on the injector, take
care not to damage it in any way.
(3) Coat a new O −ring with spindle oil or gasoline be-
fore installing −never use engine, gear or brake oil.
(e) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
(f) Check that there are no fuel leaks after doing mainte- nance anywhere on the fuel system.
(1) Remove the fuse cover on the instrument panel.
(2) Connect the TOYOTA hand− held tester to the
DLC3.
(3) Turn the ignition switch ON and TOYOTA hand −
held tester main switch ON.
NOTICE:
Do not start the engine. (4) Select the active test mode on the TOYOTA hand−held tester.
(5) Please refer to the TOYOTA hand −held tester oper-
ator ’s manual for further details.
If you have no T OYOTA hand−held tester, connect the positive
(+) and negative ( −) leads from the battery to the fuel pump con-
nector (See page SF−14 ).
(6) Pinch the fuel return hose. The pressure in the high
pressure line will rise to approx. 392 kPa (4 kgf/cm
2,
57 psi). In this state, check to see that there are no
leaks from any part of the fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(7) Turn the ignition switch to LOCK.

manual for further details.
(n) If you have no TOYOTA hand−held tester, connect the positive (+) and negative (−) leads from the battery to the
fuel pump connector (See page SF−14)
(o) Connect SST (wire) to the injector and battery for 15 se- conds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST 09842−30070
Volume:
69 − 88 cm
3 (4.2 − 5.4 cu in.) per 15 seconds
Difference between each injector:
5 cm
3 (0.3 cu in.) or less
If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the test probes of SST (wire) from the battery and check the fuel leakage from
