INSTALLATION
NOTICE:

Never use SRS parts from another vehicle. When re-
placing parts, replace them with new parts.

Never reuse the airbag sensor assembly involved in
a collision when the airbag has deployed.

Never repair a sensor in order to reuse it.
1. INSTALL AIRBAG SENSOR ASSEMBLY
(a) Using a torx wrench, install the airbag sensor assembly
with 4 screws.
Torx wrench: T40 (Part No.09042-00020 or locally
manufactured tool)
Torque: 21 N´m (210 kgf´cm, 15 ft´lbf)
(b) Connect the airbag sensor connectors.
NOTICE:

Installation of the connector is done after the sensor
assembly has been installed.

Make sure the sensor assembly is installed with the
specified torque.

If the sensor assembly has been dropped, or there are
cracks, dents or other defects in the case, bracket or
connector, replace the sensor assembly with a new
one.

When installing the senor assembly, take care that
the SRS wiring does not interfere with other parts and
is not pinched between other parts.

After installing , shake the sensor assembly to check
that there is no looseness.
2. INSTALL THESE PARTS:
(a) Console box
(b) Parking brake hole cover
(c) Console panel upper

manual for further details.
(e) If you have no TOYOTA hand-held tester, connect the
positive (+) and negative (-) leads from the battery to the
fuel pump connector.
(See step 8)
(f) Check that there is pressure in the fuel inlet hose from the
fuel filter.
HINT:
If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check the following parts:

Fuses

EFI No.2 relay

Fuel pump

ECM

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 voltage is above 12 V.
(b) Disconnect the negative (-) terminal cable from the bat-
tery.
(c) Remove the union bolt and 2 gaskets, disconnect the fuel
inlet hose from the fuel filter.
CAUTION:

Put a suitable container or shop towel under the fuel
filter.

Slowly loosen the union bolt.
(d) Install the fuel inlet hose and SST (pressure gauge) to the

(f) Connect the TOYOTA hand-held tester to the DLC3.
(See step 1 in check fuel pump operation (a) to (e).)
(g) Reconnect the negative (-) terminal cable to the battery.
(h) Turn the ignition switch ON.
(i) Measure the fuel pressure.
Fuel pressure:

2, 33 - 40 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check the following parts:
(1) Fuel hoses and connections
(2) Fuel pump
(3) Fuel filter
(4) Fuel pressure regulator
(j) Remove the TOYOTA hand-held tester from the
DLC3.
(k) Start the engine.
(l) Disconnect the vacuum sensing hose from the fuel pres-
sure regulator, and plug the hose end.
(m) Measure the fuel pressure at idle.
Fuel pressure:
226 - 275 kPa (2.3 - 2.8 kgf/cm
2, 33 - 40 psi)
(n) Reconnect the vacuum sensing hose to the fuel pressure
regulator.
(o) Measure the fuel pressure at idle.
Fuel pressure:
167 - 216 kPa (1.7 - 2.2 kgf/cm
2, 24 - 31 psi)
If pressure is not as specified, check the vacuum sensing hose
and fuel pressure regulator.
(p) Stop the engine.
(q) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure:
147 kPa (1.5 kgf/cm
2, 21 psi) or more
If pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(r) After checking fuel pressure, disconnect the negative (-)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.

(s) Reinstall the fuel inlet hose to the fuel filter with 2 new gas-
kets and the union bolt.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(t) Reconnect the negative (-) terminal cable to the battery.
(u) Check for fuel leaks.
