(b) Connect the positive (+) lead from the battery to terminal
1 and the negative (-) lead to terminal 2.
(c) Check that the motor turns (moves upward).
NOTICE:
These tests must be done quickly (within 3 - 5 seconds) to
prevent the coil from burning out.
(d) Then, reverse the polarity, and check that the motor turns
the opposite way (moves downward).
NOTICE:
These tests must be done quickly (within 3 - 5 seconds) to
prevent the coil from burning out.
HINT:
When the motor is normal, lower the antenna to its lowest posi-
tion.
If operation is not as specified, replace the antenna motor as-
sembly.

HINT:
Using the ABS actuator checker (SST), check the operation of
the actuator. If the actuator does not operate, check the opera-
tion of sub-wire harness G according to instructions on pages
DI-509.. If the solenoid and/or pump motor relay are abnormal,
replace the relay and inspect the actuator operation again.

Battery positive voltage: 10-14 V
2. DISCONNECT 2 CONNECTORS FROM ACTUATOR
3. CONNECT ACTUATOR CHECKER (SST) TO ACTUA-
TOR
(a) Connect the actuator checker (SST) to the actuator side
wire harnesses via the sub-wire harnesses (SST), as
shown.

HANDLING PRECAUTIONS ON RELATED COMPONENTS
1. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Servicing vehicle with a Supplemental Restraint System (referrerd to as the SRS in the remainder of this
manual) installed.
When handling SRS components (removal, installation or inspection, etc.), always follow the directions
given in the repair manual for the relevant model year to prevent the occurrence of accidents and airbag
malfunction.
Also take the following precautions when repairing the body:

Work must be started after 90 seconds or longer from the time the ignition switch is set to the LOCK
position and the negative (-) terminal cable is disconnected from the battery.
(The airbag system is equipped with a backup power source so that if work is started within 20 seconds
of disconnecting the negative (-) terminal cable of the battery, the airbag may be deployed.)
When the negative (-) terminal cable is disconnected 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 each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat, outside rear view mirror and power shoul-
der belt anchorage, which are all equipped with memory function, it is not possible to make a record of
the memory contents. So when the operation is finished, it will be necessary to explain this fact to the
customer, and request the customer to adjust the features and reset the memory.

When using electric welding, first disconnect the SRS connector (yellow color and 2 pins) under the
steering column near the combination switch connector on the glove compartment finish plate and lower
the front scuff plate before starting work.

5. COMPONENTS ADJACENT TO THE BODY PANELS Locations of ECUs (Cont'd)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.

Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery.
When the negative (-) terminal cable is disconnected 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 each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all
equipped with memory function, it is not possible to make a record of the memory contents.
So when the operation is finished, it will be necessary to explain this fact to the customer, and request
the customer to adjust the features and reset the memory.

Do not expose the ECUs to ambient temperatures above 80°C (176°F).
NOTICE: if it is possible the ambient temperature may reach 80°C (176°F) or more, remove the ECUs
from the vehicle before starting work.

Be careful not to drop the ECUs and not to apply physical shocks to them.
Various types of component parts are mounted directly on or adjacently to the body panels.
Strictly observe the following precautions to prevent damaging these components and the body panels
during handling.

Before repairing the body panels, remove their components or apply protective covers over the
components.

Before prying components off using screwdriver or a scraper, etc., attach protective tape to the tool
tip or blade to prevent damaging the components an the body paint.

Before removing components from the outer surface of the body, attach protective tape to the body
to ensure no damage to painted areas.
HINT: Apply touch-up paint to any damaged paint surfaces.

Before drilling or cutting sections, make sure that there are no wires, etc. on the reverse side.

HANDLING PRECAUTIONS
1. The repair procedure for plastic body parts must conform with the type of plastic material.
2. Plastic body parts are identified by the codes in the following chart.
3. When repairing metal body parts adjoining plastic body parts (by brazing, frame cutting, welding,
painting etc.), consideration must given to the property of the plastic.
* Temperatures higher than those listed here may result in material deformation during repair.

COLLISION REPAIR INFORMATION
TITLE: SRS AIRBAG COMPONENT REPLACEMENT PAGE 1 of 6
SECTION: ELECTRICAL BULLETIN #79
MODELS: ALL
DATE: AUGUST 1997
After an airbag has been deployed during a collision, it will be necessary to replace certain
components of the airbag system. Technicians can identify these parts by using the
attached matrix.
If the airbag does not deploy, yet the combination meter (airbag warning light) stays on for
more that 10 seconds after the key is turned to the ªACCº or ªONº position, it is necessary
to perform a diagnostic test. Always refer to the Toyota repair manual for the correct repair
procedure.
The attached information includes:

A matrix indicating components requiring replacement (pages 2±4).

Parts replacement note (page 5).

An example repair manual page outlining the diagnostic procedure available in
each model specific repair manual (page 6).
Toyota recommends the use of electrical repair kit (P/N 00002±04200±01) for any wiring
repairs. This kit includes a selection of numerous repair connectors, terminal ends, a repair
procedures manual and special tools specific to Toyota. The
replacement electrical wire
and connector (from the wire harness to the front sensors) is P/N 82988±24010.
Toyota also offers a video package which shows the operation of the SRS airbag system
(P/N 00401±42994).
CAUTION: SRS Airbag service work can be performed only AFTER 90 SECONDS
from the time the ignition switch is turned to the ªlockº position and the
negative (±) terminal cable is disconnected from the battery.
