POST-COLLISION DIAGNOSIS
Check and service the vehicle after collision as follows
regardless of the operation of the pre-tensioner:
SRS-ECU MEMORY CHECK
The check procedure is the same as before.
REPAIR PROCEDURE
WHEN PRE-TENSIONER OPERATES IN A COLLISION.
1. Replace the following parts with new ones.
DSRS-ECU
DFront impact sensor
DSeat belt with pre-tensioner (Refer to P.52B-12.)
2. Check harnesses for binding, connectors for damage,
poor connections, and terminals for deformation.
UNDEPLOYED AIR BAGS IN LOW-SPEED COLLISION
Check the SRS-ECU and Front impact sensor and Seat belt
with pre-tensioner. If visible damage such as dents, cracks,
or deformation are found on the the SRS-ECU and Front
impact sensor and Seat belt with pre-tensioner, replace them
with new ones. Concerning parts removed for inspection,
replacement with new parts and cautions in working, refer
to INDIVIDUAL COMPONENT SERVICE.
SRS-ECU
The check procedure is the same as before.
Front impact sensor
The check procedure is the same as before.
Seat belt with pre-tensioner
1. Check the seat belt for damage or deformation.

SRS -Seat Belt Pre-tensioner Disposal Procedures52B-14
SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES
Before disposing of a vehicle which is equipped
with seat belts with pre-tensioner, or when disposing
of the seat belts with pre-tensioner themselves,the following procedures must be used to deploy
the pre-tensioners before disposal.
UNDEPLOYED SEAT BELT PRE-TENSIONER
DISPOSAL
Caution
1. If the vehicle is to be scrapped or otherwise disposed
of, operate the pre-tensioners inside the vehicle. If
the vehicle is still to be used and only the seat belt
pre-tensioner are to be disposed of, operate the
pre-tensioners outside the vehicle.
2. Since a large amount of smoke is produced when
the pre-tensioner is operated, avoid residential areas
whenever possible.
3. Since there is a loud noise when the pre-tensioners
are operated, avoid residential areas whenever
possible. If anyone is nearby, give warning of the
impending noise.
4. Suitable ear protection should be worn by personnel
performing these procedures or by people in the
immediate area.
DEPLOYMENT INSIDE THE VEHICLE
1. Move the vehicle to an isolated spot.
2. Disconnect the negative ( - ) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work.
(Refer to P.52B-4.)
3. Operate the pre-tensioner as specified in the service
procedures that follows.
(1) Remove the center pillar trim, lower.

SRS -Seat Belt Pre-tensioner Disposal ProceduresSRS -Seat Belt Pre-tensioner Disposal Procedures52B-16
Caution
1) Before operating the pre-tensioner, see that
no one is in and near the vehicle.
2) The operation of the pre-tensioner makes the
inflator very hot. Before handling the inflator,
wait more than 30 minutes for cooling.
3) If the pre-tensioner fails to operate when the
procedures above are followed, do not go near
the pre-tensioner. Contact your local
distributor.
(7) After operation of the pre-tensioner, discard as
specified in the procedure. (Refer to P.52B-18.)
DEPLOYMENT OUTSIDE THE VEHICLE
Caution
1) This should be carried out in a wide, flat area at least
6 m away from obstacles and other people.
2) Do not operate outside if wind is high. Even in a soft
wind, ignite to windward of the pre-tensioner.
1. Disconnect the negative ( - ) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work. (Refer
to P.52B-4.)
2. Operate pre-tensioner as specified in the service
procedures that follows.
(1) Remove the seat belt pre-tensioner from the vehicle.
(Refer to P.52B-12.)
Caution
The pre-tensioner should be stored on a flat
surface and placed so that the pre-tensioner
operation surfaces are facing upward. Do not
place anything on top of them.
