ON-VEHICLE INSPECTION
1. REMOVE V-BANK COVER
(a) Using a 5 mm hexagon wrench, remove the 3 cap nuts.
(b) Loosen the V-bank cover fastener counterclockwise.
(c) Remove the V-bank cover.
2. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(1) With the engine running or cranking, use a sound
scope to check that there is normal operating noise
in proportion to engine speed.
(2) If you have no sound scope, you can check the in-
jector operating vibration with your finger.
If no sound or unusual sound is heard, check the wiring connec-
tor, injector or injection signal from the ECM.
3. INSPECT INJECTOR RESISTANCE
(a) Disconnect the injector connector.
(b) Using an ohmmeter, measure the resistance between the
terminals.
Resistance: 13.4 - 14.2 W at 20°C (68°F)
If the resistance is not as specified, replace the injector.
(c) Reconnect the injector connector.
4. REINSTALL V-BANK COVER
(a) Using 5 mm hexagon wrench, install the V-bank cover
with the 3 cap nuts.
(b) Press down the V-bank cover fastener.

SRS AIRBAG
PRECAUTION
CAUTION:

The AVALON is equipped with SRS, which comprises a driver airbag, front passenger airbag
and side airbag. Failure to carry out service operations in the correct sequence could cause
the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Fur-
ther, if a mistake is made in servicing the SRS, it is possible that the SRS may fail to operate
when required. Before performing servicing (including removal or installation of parts, inspec-
tion or replacement), be sure to read the following items carefully, then follow the correct proce-
dures described in the repair manual.

Work must be started 90 seconds after the ignition switch is turned to the ºLOCKº position and
the negative (-) terminal cable is disconnected from the battery.
(The SRS is equipped with a back-up power source so that if work is started within 90 seconds
from disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)

Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,
airbag sensor assembly, front airbag sensor or side airbag sensor assembly directly to hot air
or flames.
NOTICE:

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.

Even in cases of a minor collision where the SRS does not deploy, the steering wheel pad, front
passenger airbag assembly, side airbag assembly, airbag sensor assembly, front airbag sen-
sor and side airbag sensor assembly should be inspected.
(See page RS-15, RS-30, RS-44, RS-57, RS-64, RS-69, RS-74 and RS-79)

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.

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

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side
airbag assembly, airbag sensor assembly, front airbag sensor or side airbag sensor assembly
in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, airbag sen-
sor assembly, front airbag sensor or side airbag sensor assembly has been dropped, or if there
are cracks, dents or other defects in the case, bracket or connector, replace it with new one.

Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the system's
electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notices.

After work on the SRS is completed, perform the SRS warning light check (See page DI-349).

When the negative (-) terminal cable is disconnected from the battery, the memory of the clock
and audio system will be canceled. So before starting work, make a record of the contents mem-
orized in the audio memory system. When work is finished, reset the audio systems as they
were before and adjust the clock. This vehicle has power seat which are all equipped with
memory function. However, it is not possible to make a record of the memory contents. So when
the work is finished, it will be necessary to explain this fact to the customer, and ask the custom-
er to adjust the features and reset the memory. To avoid erasing the memory in each memory
system, never use a back- up power supply from outside the vehicle.

6. INSPECT BRUSH HOLDER
Check the brush holder insulation.
Using an ohmmeter, check that there is no continuity be-
tween the positive (+) and negative (-) brush holders.
If there is continuity, repair or replace the brush holder.
7. INSPECT CLUTCH AND GEAR
(a) Check the gear teeth on the pinion gear, idler gear and
clutch assembly for wear or damage.
If damaged, replace the gear or clutch assembly.
If damaged, also check the drive plate ring gear for wear or
damage.
(b) Check the clutch pinion gear.
Hold the starter clutch and rotate the pinion gear counter-
clockwise, and check that it turns freely. Try to rotate the
pinion gear clockwise and check that it locks.
If necessary, replace the clutch assembly.
8. INSPECT MAGNETIC SWITCH
(a) Check the pull-in coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminals 50 and C.
If there is no continuity, check and replace the magnetic switch.
(b) Check the hold-in coil open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminal 50 and the switch body.
If there is no continuity, replace the magnetic switch.
9. INSPECT BEARING
Turn the bearing by hand while applying inward force.
If resistance is felt or the bearing sticks, replace the bearing
(See page ST-1 1).
