HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check functioning of the SST.
CAUTION:
When deploying the airbag, always use the specified SST:
SRS Airbag Deployment Tool.
SST 09082−00700
(1) Connect the SST to battery.
Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (−) terminal.
HINT:
Do not connect the yellow connector which will be connected
with the supplemental restraint system.
(2) Check functioning of the SST.
Press the SST activation switch, and confirm the
LED of the SST activation switch lights up.
CAUTION:
If the LED lights up when the activation switch is not being
pressed, SST malfunction is probable, so definitely do not
use the SST.

(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.

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.
2. CHECK FUEL PRESSURE
(a) Check the battery positive voltage is above 12 V.
(b) Disconnect the negative (−) terminal cable from the bat-
tery.
(c) Remove the air cleaner assembly (See page ST−4).
(d) Remove the 2 bolts, and disconnect the engine comport-
ment R/B No.2 from the bracket on the body.

4 of the connector, and the negative (−) lead to terminal
5. Check that the fuel pump operates.
NOTICE:
These tests must be done quickly (within 10 seconds) to
prevent the coil burning out. Keep the fuel pump as far
away from the battery as possible. Always do the switching
at the battery side.
