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.

servicing or handling SRS components.
Warning labels can be found in the following

(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
and clock spring). 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.

of the air bag module or disposing of a vehicle
equipped with an air bag (Refer to GROUP
52B

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 occur to the SRS
components.
(2) If heat damage may occur during paint work,
remove the SRS-ECU, the air bag module,
clock spring, the front impact sensor, the side
impact sensor, and the seat belt pre-tensioner.
• SRS-ECU, air bag module, clock spring, front
impact sensor, the side impact sensor: 93
