(3) Even in cases of a minor collision where the SRS
does not deploy, the steering wheel pad (See page
RS−9) and front passenger airbag assembly (See
page RS−23 ) should be inspected.
(4) Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.
(5) Before repairs, remove the airbag sensor if shocks
are likely to be applied to the sensor during repairs.
(6) Never disassemble and repair the airbag sensor as-
sembly, steering wheel pad or front passenger air-
bag assembly in order to reuse them.
(7) If the airbag sensor assembly, steering wheel pad
or front passenger airbag assembly have been
dropped, or if there are cracks, dents or other de-
fects in the case, bracket or connector, replace
them with new ones.
(8) Do not directly expose the airbag sensor assembly, steering wheel pad or front passenger airbag as-
sembly to hot air or flames.
(9) Use a volt/ohmmeter with high impedance (10 kΩ/V
minimum) for troubleshooting of the electrical cir-
cuit.
(10) Information labels are attached to the periphery of the SRS components. Follow the instructions on the
notices.
(11) After work on the supplemental restraint system is completed, check the SRS warning light (See page
DI−240 ).
(c) SPIRAL CABLE (in Combination Switch) The steering wheel must be fitted correctly to the steering
column with the spiral cable at the neutral position, other-
wise cable disconnection and other troubles may result.
Refer to SR−19 of this manual concerning correct steer-
ing wheel installation.

(d) STEERING WHEEL PAD (with Airbag)
(1) When removing the steering wheel pad or handlinga new steering wheel pad, it should be placed with
the pad top surface facing up.
Storing the pad with its metallic surface facing up-
ward may lead to a serious accident if the airbag in-
flates for some reason. In addition do not store a
steering wheel pad on top of another one.
(2) Never measure the resistance of the airbag squib. (This may cause the airbag to deploy, which is very
dangerous.)
(3) Grease should not be applied to the steering wheel
pad and the pad should not be cleaned with deter-
gents of any kind.
(4) Store the steering wheel pad where the ambient temperature remains below 93 °C (200° F), without
high humidity and away from electrical noise.
(5) When using electric welding, first disconnect the air-
bag connector (yellow color and 2 pins) under the
steering column near the combination switch con-
nector before starting work.
(6) When disposing of a vehicle or the steering wheel pad alone, the airbag should be deployed using an
SST before disposal (See page RS−11).
Perform the operation in a safe place away from
electrical noise.

3. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to yo\
ur customer.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c) Avoid spark jump test. (1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid prolonged engine compression measurement. Engine compression tests must be done as rapidly as possible.
(e) Do not run engine when fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the con\
verter.
(f) Avoid coasting with ignition turned off.
(g) Do not dispose of used catalyst along with parts contaminated with gasol\
ine or oil.
4. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two− way radios and cellular telephones, observe
the following precautions. (1) Install the antenna as far as possible away from the ECU and sensors of the vehicle’\
s electronic
system.
(2) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and se\
nsors of the ve- hicle’s electronic systems. For details about ECU and sensors locations, refer\
to the section on
the applicable component.
(3) Avoid winding the antenna feeder together with other wiring as much as possible, and also avoid
running the antenna feeder parallel with other wire harnesses.
(4) Check that the antenna and feeder are correctly adjusted.
(5) Do not install powerful mobile communications system.
5. FOR USING OBD II SCAN TOOL OR TOYOTA HAND −HELD TESTER
CAUTION:
Observe the following items for safety reasons:
Before using the OBD II scan tool or TOYOTA hand −held tester, the OBD II scan tool’s instruc-
tion book or TOYOTA hand −held tester’s operator manual should be read thoroughly.
Be sure to route all cables securely when driving with the OBD II scan too\
l or TOYOTA hand −
held tester connected to the vehicle. (i.e. Keep cables away from feet,\
pedals, steering wheel
and shift lever.)
Two persons are required when test driving with the OBD II scan tool or TOYOTA hand −held
tester, one person to drive the vehicle and the other person to operate the OBD\
II scan tool or
TOYOTA hand−held tester.

HINT:
When the SRS warning light remains lit up and the DTC is the normal code\
, this means a source drop
voltage.
This malfunction is not stored in memory by the airbag sensor assembly a\
nd if the power source volt-
age returns to normal, the SRS warning light will automatically go out.
When 2 or more codes are indicated, the codes will be displayed in numer\
al order starting from the
lowest numbered code.
If a code not listed on the chart is displayed, the airbag sensor assemb\
ly is faulty.
