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
MANAGER!

REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Loosen the 2 drain plugs (for the engine and radiator),
and drain the coolant.
HINT:
To prevent the coolant from spraying over the cylinder block,
connect the rubber hose (inside diameter 6 - 8 mm) in the mar-
ket to the union pipe under.
(c) Close the drain plugs.
Torque:

29 N´m (300 kgf´cm, 22 ft´lbf)
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.
Use a good brand of ethylene-glycol base coolant
and mix it according to the manufacturer's direc-
tions.
Using coolant which includes more than 50 % ethyl-
ene-glycol (but not more than 70 %) is recom-
mended.
NOTICE:
Do not use an alcohol type coolant.
The coolant should be mixed with demineralized wa-
ter or distilled water.
