5. ADJUST CAMBER
NOTICE:
After the camber has been adjusted, inspect the toe−in.
(a) Remove the front wheels.
(b) Remove the 2 nuts on the lower side of the shock absorb-
er.
(c) Coat the threads of the nuts with engine oil.
(d) Temporarily install the 2 nuts.
(e) Adjust the camber by pushing or pulling the lower side of
the shock adjustment is required.
(f) Tighten the 2nuts.
Torque: 158 N·m (1,610 kgf·cm, 117 ft.lbf)
(g) Install the front wheels.
Torque: 103 N·m (1,050 kgf·cm, 76 ft.lbf)
(h) Check the camber.
HINT:
Try to adjust the camber to the center value.
Adjusting value for the set bolts is 6’ − 30’ (0.1° − 0.5°).
If the camber is not within the specification, using the table be-
low, estimate for how much additional camber adjustment will
be required, and select the camber adjusting bolt.

PRECAUTION
1. BEFORE WORKING ON THE FUEL SYSTEM, DISCON-
NECT THE NEGATIVE (−) TERMINAL CABLE FROM
THE BATTERY
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative (−) terminal cable is removed.
Therefore, if necessary, read the diagnosis before removing the
terminal.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON THE FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) In event of engine misfire, these precautions should be
taken.
(1) Check proper connection to battery terminals, etc.
(2) After repair work, check that the ignition coil termi-
nals and all other ignition system lines are recon-
nected securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Precautions when handling oxygen sensor.
(1) Do not allow oxygen sensor to drop or hit against an
object.
(2) Do not allow the sensor to come into contact with
water.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RADIO SYS-
TEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, etc.,
first disconnect the power by either turning the ignition
switch to LOCK or disconnecting the negative (−) terminal
cable from the battery.
HINT:
Always check the diagnostic trouble code before disconnecting
the negative (−) terminal cable from the battery.

(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative (−) cables.
(c) Do not permit parts to receive a severe impact during re-
moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal con-
tact can cause further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care is required when pulling out and inserting wiring con-
nectors.
(i) Release the lock and pull out the connector, pulling on the
connectors.
(j) Fully insert the connector and check that it is locked.
(k) Use SST for inspection or test of the injector or its wiring
connector.

8. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline will spill out, so observe the following
procedures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch to LOCK.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.

(d) Check that there are no fuel leaks after performing main-
tenance anywhere on the fuel system.
(1) Connect the TOYOTA hand−held tester to the
DLC3.
(2) Turn the ignition switch ON and TOYOTA hand−
held tester main switch ON.
NOTICE:
Do not start the engine.
(3) Select the active test mode on the TOYOTA hand−
held tester.
(4) Please refer to the TOYOTA hand−held tester oper-
ator ’s manual for further details.
(5) If you have no TOYOTA hand−held tester, connect
the positive (+) and negative (−) leads from the bat-
tery to the fuel pump connector (See page
SF−5).
(6) Pinch the fuel inlet hose.
The pressure in the high pressure line will rise to
approx. 400 kPa (4 kgf/cm
2, 57 psi). In this state,
check 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.
(8) Disconnect the TOYOTA hand−held tester from the
DLC3.
(9) Start the engine.
NOTICE:
Keep cranking the engine until the air is removed from the
fuel line.
(10) After the engine starts, check again that there are
no fuel leaks.

If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check the H−fuse, fuses, EFI main relay,
circuit opening relay, fuel pump, ECM and wiring connections.
(g) Turn the ignition switch to LOCK.
(h) Disconnect the TOYOTA hand−held tester from the
DLC3.
