PRECAUTION

1.

FOR VEHICLES EQUIPPED WITH SRS AIRBAG AND

SEAT BELT PRETENSIONER

(a) The AVENSIS/CORONA is equipped with an SRS (Sup-

plemental Restraint System), such as the driver airbag,

front passenger airbag, side airbags, curtain shield airbag

and seat belt pretensioners.

Failure to carry out service operations in the correct se-

quence could cause the supplemental restraint system to

unexpectedly deploy during servicing, possibly leading to

a serious accident.

Further, if a mistake is made in servicing the supplemental

restraint system, it is possible the SRS may fail to operate

when required. Before servicing (including removal or

installation of parts, inspection or replacement), be sure

to read the following items carefully, then follow the cor-

rect procedure described in this manual.

(b) GENERAL NOTICE

Negative Cable

(1) Malfunction symptoms of the supplemental re-

straint system are difficult to confirm, so the diag-

nostic 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 (See Pub. No. RM599E,

page DI–152).

BO4111

(2) Work must be started after 90 seconds from the

time the ignition switch is turned to the ”LOCK” posi-

tion and the negative (–) terminal cable is discon-

nected 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 neg-

ative (–) terminal cable from the battery, the SRS

may deploy.)

When the negative (–) terminal cable is discon-

nected 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

the each memory system. Then when work is fin-

ished, reset the clock and audio systems as before.

To avoid erasing the memory of each memory sys-

tem, never use a back–up power supply from out-

side the vehicle.

(3) Even in cases of a minor collision where the SRS

does not deploy, the steering wheel pad (See Pub.

No. RM599E, page RS–15), front passenger airbag

assembly (See Pub. No. RM599E, page RS–28),

side airbag assemblies (See Pub. No. RM698E,

page RS–11), curtain shield airbag assemblies

(See Pub. No. RM698E, page RS–25) and seat belt

pretensioners (See Pub. No. RM599E, page

BO–152) 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, side airbag sensor assembly, steering

wheel pad, front passenger airbag, side airbag or

seat belt pretensioner in order to reuse them.

(7) If the airbag sensor assembly, side airbag sensor

assembly, steering wheel pad, front passenger air-

bag, side airbag or seat belt pretensioner have

been dropped, or if there are cracks, dents or other

defects in the case, bracket or connector, replace

them with new ones.

(8) Do not directly expose the airbag sensor assembly,

side airbag sensor assembly, steering wheel pad,

front passenger airbag, side airbag or seat belt pre-

tensioner 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 Pub.

No. RM599E, page DI–152).

(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 Pub. No. RM599E, page SR–18 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.

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 Pub. No. RM599E, page

RS–17).

Carry out the operation in a safe place away from

electrical noise.
