(i)

AIRBAG SENSOR ASSEMBLY
(1)

Never reuse the airbag sensor assembly involved
in a collision when the SRS has deployed.

(2)

The connectors to the airbag sensor assembly
should be connected or disconnected with the sen-
sor mounted on the floor. If the connectors are con-
nected or disconnected while the airbag sensor as-
sembly is not mounted to the floor, it could cause
undesired ignition of the supplemental restraint sys-
tem.

(3)

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, even if only loosening the
set bolts of the airbag sensor assembly.

(j)

WIRE HARNESS AND CONNECTOR
The SRS wire harness is integrated with the cowl wire har-
ness assembly and floor wire harness assembly. All the
connectors for the system are also a standard yellow col-
or. If the SRS wire harness becomes disconnected or the
connector becomes broken due to an accident, etc., re-
pair or replace it.

FOR VEHICLES EQUIPPED WITH VEHICLE SKID
CONTROL (VSC) SYSTEM

NOTICE:

Even if TRAC is initially OFF, it automatically be-
comes ON when the vehicle speed becomes about 30
km/h (19 mh) or more. Therefore, please drive in the
test mode to avoid dangerous situations caused by
the TRAC control.

VSC/ABS may be failed when the vehicle is driven on
the two–wheel chassis dynamo. Therefore, after driv-
ing on the chassis dynamo, please clear DTC before
normal driving. Please refer to the page 

DI–899

 for the

method of clearing DTC.

Fasten the vehicle with the lock chain.

(a)

Confirm VSC system is OFF.
(1)

Turn the ignition switch OFF.

(2)

Using SST, connect terminals Ts and CG of DLC3.

SST

(4)

Check that the VSC TRAC warning light blinks.

(5)

After the measurement, remove the SST and re-
start the engine. At this time, make sure that the
VSC TRAC warning light is off.

(b)

Notice in VSC operation.
(1)

Removal and reinstallation of VSC–related compo-
nents may cause misadjustment of them. Do not re-
move or reinstall them unless necessary.

(2)

When conducting VSC–related operations, do not
fail to make sure that the preparation and the finish-
ing of the operation are all performed in accordance
with the direction in this text.

3.

FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER

CAUTION:
If a 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 your 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 converter.

(f)

Avoid coasting with ignition turned off.

(g)

Do not dispose of used catalyst along with parts contaminated with gasoline 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 sensors of the ve-
hicle’s electronic systems. For details about ECU and sensor locations, refer to the section on
the applicable component.

(3)

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 harness.

(4)

Check that the antenna and feeder are correctly adjusted.

(5)

Do not install powerful mobile communication system.

FOR USING OBD II SCAN TOOL OR TOYOTA HAND–HELD TESTER

CAUTION:
Observe the following 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 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 OBD II scan tool or TOYOTA hand–held
tester, one person to drive the vehicle and one person to operate the OBD II scan tool or TOYO-
TA hand–held tester.

INITIALIZATION

NOTICE:
When disconnecting the battery terminal, initialize the following systems after the terminal is recon-
nected.

System Name

See Step No.

Back Door Power Window Control System

Step 1

INITIALIZE BACK DOOR POWER WINDOW CONTROL SYSTEM
NOTICE:
Resetting the power window regulator motor (initializing the pulse sensor) is necessary if: 1) the bat-
tery terminal cable is disconnected; 2) the back door ECU, wire harness, power window regulator
switch, power window regulator assembly and power window regulator motor are replaced or re-
moved/installed; or 3) the P/W fuse is replaced or removed. If resetting is not performed, the master
switch assembly will not be able to operate the AUTO operation function, jam protection function and
remote operation function.
