REMOVAL
REMOVE ANTENNA ROD
HINT:
Do this operation with the negative (-) terminal cable connected
to the battery.
(a) Turn the ignition switch to ºLOCKº position.
(b) Remove the antenna nut.
(c) Press the ºAMº button on the radio receiver, and simulta-
neously turn the ignition switch to ºACCº position.
HINT:
The rod will extend fully and be released from the motor
antenna.
After removing the antenna rod, leave the ignition switch
at ºACCº.
NOTICE:
To prevent body damage when the antenna rod is released,
hold the rod while it comes out.

INSPECTION
1. INSPECT RELAY CIRCUIT
Disconnect the connector from the relay and inspect connector
on wire harness side, as shown in the chart.
If circuit is not as specified, replace the relay.

2. INSPECT MOTOR ANTENNA
(a) Install antenna nut.
(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.

INSTALLATION
INSTALL ANTENNA ROD
(a) Insert the cable of the rod until it reaches the bottom.
HINT:
When inserting the cable, the teeth on the cable must face
toward the rear of the vehicle.
Insert the cable approx. 400 mm.
(b) Wind the cable to retract the rod by turning the ignition
switch to ºLOCKº position.
HINT:
If the ignition switch is already in ºLOCKº position, do step
1 (c) first, then turn the ignition switch to ºACCº position.
In case the cable is not wound, twist it as shown in the il-
lustration.
Even if the rod has not retracted fully, install the antenna
nut and inspect the antenna rod operation. It will finally re-
tract fully.
(c) Inspect the antenna rod operation by pushing the radio
wave band select buttons.

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.

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.
NOTE: PLEASE ROUTE THIS BULLETIN TO YOUR COLLISION REPAIR CENTER

ON-VEHICLE INSPECTION
1. CHECK COOLING FAN OPERATION WITH LOW
TEMPERATURE (Below 91°C (196°F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and ECT switch, and check
for a separated connector or severed wire between the No.1 ra-
diator fan relay and ECT switch.
(c) Disconnect the ECT switch connector.
(d) Check that the cooling fan rotates.
If not, check the No.1 radiator relay, No.2 radiator fan relay,
cooling fan, fuses, and check for short circuit between the No.1
radiator fan relay and ECT switch.
(e) Reconnect the ECT switch connector.
2. CHECK COOLING FAN OPERATION WITH HIGH
TEMPERATURE (Above 100°C (212°F))
(a) Start the engine, and raise coolant temperature to above
100°C (212°F).
(b) Check that the cooling fan rotates.
If not, replace the ECT switch.
3. INSPECT COOLING FAN
(a) Disconnect the fan connector.
(b) Connect battery and ammeter to the cooling fan connec-
tor.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage: 2.5 - 4.5 A
(d) Reconnect the fan connector.
