(3) Even in cases of a minor collision where the SRS
does not deploy, the steering wheel pad, front pas-
senger airbag assembly and front airbag sensor
should be inspected (See page SR- 8, RS- 22,
RS-34).
(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 it.
(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 expose the airbag sensor assembly, steer-
ing wheel pad and front passenger airbag assembly
directly to hot air or flames.
(9) Use a volt/ohmmeter with high impedance (10 kW/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
RS-1).
(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 of this manual concerning correct steering wheel
installation.

(d) STEERING WHEEL PAD (with Airbag)
(1) When removing the steering wheel pad or handling
a new steering wheel pad, it should be placed with
the pad top surface facing up.
In this case, the twin-lock type connector lock lever
should be in the locked state and care should be
taken to place it so the connector will not be dam-
aged. In addition do not store a steering wheel pad
on top of another one. Storing the pad with its metal-
lic surface facing upward may lead to a serious acci-
dent if the airbag inflates for some reason.
(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-1 1).
Carry out the operation in a safe place away from
electrical noise.

(c) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the vehicle's
electronics systems. For details about ECU and sensors locations, refer to the section on the applica-
ble component.
(d) Do not wind the antenna feeder together with the other wiring. As much as possible, also avoid running
the antenna feeder parallel with other wire harnesses.
(e) Confirm that the antenna and feeder are correctly adjusted.
(f) Do not install powerful mobile communications system.
4. FOR USING OBDII SCAN TOOL OR TOYOTA HAND-HELD TESTER
Observe the following for safety reasons:

Before using the OBDII scan tool or TOYOTA hand-held tester, the OBDII scan tool's instruction
book or TOYOTA hand-held tester's operator manual should be read thoroughly.

Be sure to route all cables securely when driving with the OBDII scan tool 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 OBDII scan tool or TOYOTA hand-held tes-
ter, one person to drive the vehicle and one person to operate the OBDII scan tool or TOYOTA
hand-held tester.
5. FOR VEHICLES EQUIPPED WITH TRACTION CON-
TROL (TRAC) SYSTEM
When using a 2 wheel drum tester such as a speedometer tes-
ter or chassis dynamometer, etc., or jacking up the rear wheels
and driving the wheels, always push in the TRAC cut (ºTRAC
OFFº) switch and turn the TRAC system OFF.
(a) Confirm TRAC system is OFF
(1) Press the TRAC cut (ºTRAC OFFº) switch.
(2) Check that the TRAC OFF indicator light comes on
when the TRAC system is turned off by the TRAC
cut switch.
HINT:
The TRAC OFF indicator light should always operate right after
the engine is restarted.
(3) Begin measurements.
