PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B ± Supplemental Restraint System (SRS).
For safe operations, 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 is designed to retain enough voltage to deploy the air bags even after the battery has
been disconnected. Serious injury may result from unintended air bag deployment if work is done
on the SRS immediately after the battery cable is disconnected.
(3) Warning/caution labels must be heeded when servicing or handling SRS components.
Warning/caution labels are attached in the following locations.
D Sun visor
D Glove box
D SRS air bag control unit (SRS-ECU)
D Steering wheel
D Steering gear box
D Driver's and passenger's air bag modules
D Clock spring
D Side air bag modules
D Side impact sensors
D Instrument panel
D Hood
D Seat belt with 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 modules should be stored on a flat surface and placed so that the deployment surfaces
are facing upward.
Do not place anything on top of them.
(6) Never attempt to disassemble or repair the SRS components (SRS air bag control unit, air bag
modules, clock spring and side impact sensors). If faulty replace them.
(7) Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure
that the system functions properly.
(8) Be sure to deploy the air bag before disposing of the air bag modules or disposing of a vehicle
equipped with air bag. (Refer to GROUP 52B ± Air Bag Module Disposal Procedures.)
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) SRS components should not be subjected to heat over 93_C, so remove the SRS components
before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.
