(3) Do not remove the EPDM protector on the outside
of the nylon tube.
(4) Must not close the piping with the nylon tube by
bending it.
(i) Check that there are no fuel leaks after doing mainte-
nance anywhere on the fuel system.
(1) Connect a TOYOTA hand±held tester to the DLC3.
(2) Turn the ignition switch ON and push the 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±6)
(6) Check that there are no leaks from any part of the
fuel system.

PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM,
DISCONNECT NEGATIVE (±) TERMINAL CABLE
FROM BATTERY
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative (±) terminal cable is removed from
the battery.
Therefore, if necessary, read the diagnosis before removing the
negative (±) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEATHER 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 the oxygen sensor.
(1) Do not allow the 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 A MOBILE RADIO
SYSTEM (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) Be careful during troubleshooting as there are numerous
transistor circuit, and even slight terminal contact 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 should be taken when pulling out and inserting wir-
ing connectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) 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 these proce-
dures:
(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.
