GENERAL INFORMATION
To improve safety, the SRS and seat belts with
pre-tensioner. These systems enhance collision
safety by restraining the front passengers in case
of an accident. The SRS works with the
pre-tensioner simultaneously when a collision is
detected.
The SRS consists of two air bag modules, SRS
air bag control unit (SRS-ECU), SRS warning lamp
and clock spring. The air bags are located in the
center of the steering wheel, above the glove box.
Each air bag has a folded air bag and an inflator
unit. The SRS-ECU under the floor console monitors
the system and has a safing G-sensor and an
analog G-sensor. The warning lamp on theinstrument panel indicates the operational status
of the SRS. The clock spring is installed in the
steering column. The seat belt pre-tensioner is built
into the front seat belt retractor. Only authorized
service personnel should do work on or around
the SRS components and seat belt with
pre-tensioner. Those service personnel should read
this manual carefully before starting any such work.
Extreme care must be used when servicing the
SRS to avoid injury to the service personnel (by
inadvertent deployment of the air bags or
inadvertent operation of the seat belt with
pre-tensioner) or the driver (by rendering the SRS
or the seat belt with pre-tensioner inoperative).

SRS - Individual Component Service/Warning/Caution Labels52B-49
INDIVIDUAL COMPONENT SERVICE
If the SRS components and seat belt with pre-tensioner are to be removed or replaced as a result of
maintenance, troubleshooting etc., follow the service procedures that follow.
Caution
1. SRS components and seat belt with pre-tensioner should not be subjected to heat, so remove
the SRS-ECU, driver’s air bag module, steering wheel -air bag module,front
passenger’s air bag module, clock spring, and seat belt with pre-tensioner before drying or
baking the vehicle after painting.
DFront impact sensor, SRS-ECU, Air bag module, clock spring: 93_C or more
DSeat belt with pre-tensioner: 90_C or more
Recheck SRS system operability after re-installing them.
2. If the SRS components and seat belt with pre-tensioner are removed for the purpose of check,
sheet metal repair, painting, etc., they should be stored in a clean, dry place until they are
reinstalled.
WARNING/CAUTION LABELS
Caution labels on the SRS are attached in the
vehicle as shown. Follow label instructions whenservicing the SRS. If the label(s) are dirty or
damaged, replace with new one(s).

Disposal Procedures52B-66
Front passenger’s air bag module
(1) Remove the glove box.
(Refer to GROUP 52A – Instrument Panel.)
(2) Disconnect the front passenger’s air bag module 2-pin
connector (red) and instrument panel wiring harness
connector (2-pin, red).
NOTE
Once disconnected from the instrument panel wiring
harness, both electrodes of the front passenger’s air
bag module short automatically. This prevents the
front passenger air bag from accidental deployment
caused by static, etc.
(3) Connect deployment harnesses longer than 6 m to
each SRS air bag adapter harness and insulate the
connections with plastic tape.
Also, connect the deployment harnesses in the other
ends to short, thereby preventing the front
passenger’s air bag from accidental deployment
caused by static etc.
(4) Connect the SRS air bag adapter harness to the
front passenger’s air bag module 2-pin connector
(red) and route the deployment harnesses out of the
vehicle.
(5) Close all the doors with the windows fully closed and
put a cover over the vehicle to minimize report.
Caution
The cover is required as the glass, if already
damaged, may break.
