FOR THE TOYOTA DEALER
COLLISION REPAIR INFORMATION
TITLE: SRS AIRBAG COMPONENT REPLACEMENT PAGE 1 of 4
SECTION: ELECTRICAL BULLETIN #83
MODELS: ALL
DATE: MAY 1998
After an airbag has been deployed during a collision, it will be necessary to replace certain
components of the SRS system. Technicians can identify these parts by using the attached
matrix.
If, after the vehicle has been completely repaired, the airbag warning light stays on for
more than 6 seconds while the key is turned to the ªACCº or ªONº position, it is necessary
to perform a diagnostic test. Always refer to the model±specific Toyota Repair Manual for
the correct repair procedure.
The attached information includes:
A matrix indicating components requiring replacement (page 3).
Parts replacement notes (page 4).
An example Repair Manual page outlining the diagnostic procedure available in
each model±specific Repair Manual (page 2).
On some vehicles the front sensors may be replaced. Please refer to the model±specific
repair manual concerning front airbag sensor replacement requirements before performing
this repair. Three part numbers are available for
replacement electrical wire and
connectors from the wire harness to the front SRS sensors. They are P/N 82988±24010,
82988±50010, and 82988±33010.
Toyota also offers a video package which outlines the operation of the SRS airbag system
(P/N 00401±42994).
NOTE: PLEASE ROUTE THIS BULLETIN TO YOUR COLLISION REPAIR CENTER
MANAGER!

Note 2 ± Visually inspect and replace the following items if deformed:
Instrument panel and Instrument panel reinforcement
Glove compartment and glove compartment door
Note 2a ± Same as note 2 without involving the glove compartment.
Note 3 ± If the SRS wire harness is damaged only at the connectors to the front
sensors:
Use a repair wire specially designed for use in the SRS airbag system at the front sensor
(PN 82988±24010/50010/33010).
OR
Replace the entire wire harness assembly.
Note 3a ± Replace the entire wire harness if damaged or has been found to be faulty
during troubleshooting.
Note 4 ± Replace the following items if deformed or if diagnostic tests show a fault:
Steering wheel (If the horn button contact plate has been deformed, never attempt to
repair it±always replace the steering wheel).
Spiral cable
Note 5 ± Replace center airbag sensor assembly if:
Center airbag sensor assembly has been found faulty in troubleshooting.
Center airbag sensor assembly shows evidence of the following:
1. Deformation of the bracket or case
2. Vinyl seal broken
3. Damage to connector

Note 6 ± Replace side impact sensors and side airbag assembly with seat cover if
deployed. Side airbag circuits are independent from each other, and one
side may deploy while the other does not.
Note 7 ± 1998 Tacoma is equipped with a passenger airbag cutoff switch. If the
