SRS
NOTICE: When inspecting or repairing the SRS, perform the operation in accordance with the following
precautionary instructions and the procedure and precautions in the Repair Manual for the applicable model year.

Malfunction symptoms of the supplemental restraint system are difficult to confirm, so the diagnostic trouble
codes become the most important source of information when troubleshooting.
When troubleshooting the supplemental restraint system, always inspect the diagnostic trouble codes before
disconnecting the battery.

Work must be started after 90 seconds from the time the Ignition SW is set to the LOCKº position and the
negative (-) terminal cable is disconnected from the battery.
(The supplemental restraint system is equipped with a back-up power source so that if work is started within 90
seconds of disconnecting the negative (-) terminal cable of the battery, the SRS may be activated.)
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio systems
will be cancelled. So before starting work, make a record of the contents memorized by each memory system.
When work is finished, reset the clock and audio system as before and adjust the clock.
To avoid erasing the memory of each memory system, never use a back-up power supply from outside the
vehicle.

When removing the steering wheel pad or handling a new steering wheel pad, keep the pad upper surface facing
upward. Also, lock the lock lever of the twin lock type connector at the rear of the pad and take care not to
damage the connector.
(Storing the pad with its metallic surface up may lead to a serious accident if the SRS inflates for some reason.)

Always store a removed or new front passenger airbag assembly with the airbag door facing up. Storing the
airbag assembly with the airbag door facing down could cause a serious accident if the airbag inflates.

Store the steering wheel pad where the ambient temperature remains below 93C (200F), without high humidity
and away from electrical noise.

Never use SRS parts from another vehicle. When replacing SRS parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, airbag sensor assembly.

Before repairing the body, remove the airbag sensors if during repair shocks are likely to be applied to the
sensors due to vibration of the body or direct tapping with tools or other parts.

Do not reuse a steering wheel pad.
After evaluating whether the airbag sensor assembly is damaged or not, decide whether or not to reuse it.
(See the Repair Manual for the method for evaluating the airbag sensor assembly.)

When troubleshooting the supplemental restraint system, use a high-impedance (Min. 10 kW/V) tester.

The wire harness of the supplemental restraint system is integrated with the cowl wire harness assembly. The
vehicle wiring harness exclusively for the airbag system is distinguished by corrugated yellow tubing, as are the
connectors.

Do not measure the resistance of the airbag squibs.
(It is possible this will deploy the airbag and is very dangerous.)

If the wire harness used in the supplemental restraint system is damaged, replace the whole wire harness
assembly.

INFORMATION LABELS (NOTICES) are attached to the periphery of the SRS components. Follow the
instructions on the notices.

INSPECTION
HINT:
This check is used only to determine whether or not the idle CO/
HC complies with regulations.
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All accessories switched OFF
(e) All vacuum lines properly connected
HINT:
All vacuum hoses for EGR system, etc. should be properly con-
nected.
(f) SFI system wiring connectors fully plugged
(g) Ignition timing checked correctly
(h) Transmission in neutral position
(i) Tachometer and CO/HC meter calibrated by hand
2. START ENGINE
3. RACE ENGINE AT 2,500 RPM FOR APPROX. 180
SECONDS
4. INSERT CO/HC METER TESTING PROBE AT LEAST
40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
5. IMMEDIATELY CHECK CO/HC CONCENTRATION AT
IDLE AND/OR 2,500 RPM
HINT:
When performing the 2 mode (2,500 rpm and idle) test, follow
the measurement order prescribed by the applicable local regu-
lations.

(i) Connect the TOYOTA hand-held tester to the DLC3.
(j) Turn the ignition switch ON and TOYOTA hand-held tes-
ter main switch ON.
NOTICE:
Do not start the engine.
(k) Select the active test mode on the TOYOTA hand-held
tester.
(l) Please refer to the TOYOTA hand-held tester operator's
manual for further details.
(m) If you have no TOYOTA hand-held tester, connect the
positive (+) and negative (-) leads from the battery to the
fuel pump connector.
(n) 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 09842-30060
Injection volume:
111 - 141 cm
3 (6.8 - 8.6 cu in.) per 15 sec.
Difference between each injector:
10 cm
3 (0.6 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 tester probes of
SST (wire) from the battery and check the fuel leakage
from the injector.
SST 09842-30060
Fuel drop:
One drop or less per minutes
(b) Turn the ignition switch to LOCK.
(c) Disconnect the negative (-) terminal cable from the bat-
tery.
(d) Remove the SST.
SST 09268-41046
(e) Reconnect the fuel inlet hose to the fuel filter with 2 new
gaskets and the union bolt.
Torque: 29 N´m (300 kgf´cm, 22 ft´lbf)
(f) Reconnect the fuel return hose to the fuel return pipe.
(g) Remove the 6 bolts, 3 injector holders and 6 insulators.
(h) Disconnect the TOYOTA hand- held tester from the
DLC3.
