INSPECTION
· Check the SRS-ECU and brackets for dents, cracks or
deformation.
· Check connectors and lock lever for damage, and
terminals for deformation
Caution
If a dent, crack, deformation or rust is discovered,
replace the SRS-ECU with a new one.
NOTE
For checking of the SRS-ECU other than described
above, refer to the section concerning troubleshooting.
(Refer to P.52B-5.)
AIR BAG MODULES AND CLOCK SPRING
Caution
1. Disconnect the battery (-) terminal and wait
for 60 seconds or more before starting
work. Furthermore, the disconnected
battery terminal should be covered with
tape to insulate it. (Refer to P.52B-3)
2. Never attempt to disassemble or repair the
air bag modules or clock spring.
If faulty, replace it.
3. do not drop the air bag modules or clock
spring or allow contact with water, grease
or oil.
Replace it if a dent, crack, deformation or
rust is detected.4. The air bag modules should be stored on a
flat surface and placed so that the pad
surface is facing upward.
Do not place anything on top of it.
5. Do not expose the air bag modules to
temperatures over 93° C.
6. After deployment of an air bag, replace the
clock spring with a new one.
7. Wear gloves and safety glasses when
handling air bags that have already
deployed.
8. An undeployed air bag module should only
be disposed of in accordance with the
procedures (Refer to P.52B-31.)
