PRECAUTIONS BEFORE SERVICE
M1001000500312
SUPPLEMENTAL RESTRAINT SYSTEM
(SRS)
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B, Supplemental
Restraint System (SRS). For safe operation,
please follow the directions and heed all
warnings.
(2) Wait at least 60 seconds after disconnecting
the battery cable before doing any further
work. The SRS system is designed to retain
enough voltage to deploy the air bag even
after the battery has been disconnected.
Serious injury may result from unintended air
bag deployment if work is done on the SRS
system immediately after the battery cable is
disconnected.
(3) Warning labels must be heeded when
servicing or handling SRS components.
Warning labels can be found in the following
locations.
• Hood
• Front impact sensor, side impact sensor
• Sun visor
• Glove box
• SRS-ECU
• Steering wheel
• Air bag module, side−airbag modules
• Clock spring
• Steering gear box
• Seat belt pre-tensioner
(4) Always use the designated special tools and
test equipment.
(5) Store components removed from the SRS in a
clean and dry place. The air bag module
should be stored on a flat surface and placed
so that the pad surface is facing upward.
(6) Never attempt to disassemble or repair the
SRS components (SRS-ECU, air bag module,
clock spring and seat belt pre-tensioner). If
there is a defect, replace the defective part.
(7) Whenever you finish servicing the SRS, check
the SRS warning light operation to make sure
that the system functions properly.
(8) Be sure to deploy the air bag before disposing
of the air bag module or disposing of a vehicle
equipped with an air bag. (Refer to GROUP
52B, Air Bag Module Disposal Procedures
P.52Ba-48
.)
2. Observe the following when carrying out
operations on places where SRS components are
installed, including operations not directly related
to the SRS air bag.
(1) When removing or installing parts, do not allow
any impact or shock to the SRS components.
(2) If heat damage may occur during paint work,
remove the SRS components. After re-
installing them, check the SRS warning light
operation to make sure that the system
functions properly.
• SRS-ECU, air bag module, clock spring:
93
°C (200°F) or more
• Seat belt pre-tensioner: 90°C (194°F) or
more
