GENERAL before Service
PRECAUTIONS BEFORE SERVICE.
SUPPLEMENTAL RESTRAINT SYSTEM
1. to follow when servicing SRS
(1) Be sure to read GROUP Supplemental Restraint System
For safe operations, please follow the directions a nd heed all
(2) Always use the designated special tools and tes t equipment.
(3) Wait at least 60 seconds after disconnecting the battery cable before” 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 bat tery cable is disconnected.
(4) Never attempt to disassemble or repair the SRS components (SRS-ECU air bag module and
clock spring). If faulty, replace it.
(5) Warning labels must be heeded when servicing or handling SRS components. Warning labels
are located in the following locations.
Sun visor
l Glove box
. S R S - E C U
l Steering wheel
l Air bag module
l Clock spring
l Steering gear and linkage clamp
(6) Store components removed from the SRS
a clean and dry place.
The air bag module should be stored on a flat surfa ce and placed so that the pad surface is’
facing upward.
Do not place anything on top of it.
(7) 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
Air Bag Module Disposal Procedures.)
(8) Whenever you finish servicing the
check the SRS warning light operation to make sure
that the system functions properly.
2.Observe the following when carrying out operations on places where SRS components are installed,’
.,
including operations not directly related to the SR S 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 so remove the SRS compo-
nents before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lig ht operation to make sure that the system
functions properly.
SERVICING THE ELECTRICAL SYSTEM
1. Note the following before proceeding with work o n the
electrical system.
Note that the following must never be done:
Unauthorized modifications of any electrical device or
wiring, because such modifications might lead to a vehicle
malfunction, over-capacity or short-circuit that co uld result
in a fire in the vehicle.
2.When servicing the electrical system, disconnect th e nega-
tive cable terminal from the battery.

turns counterclockwise to align the
mating marks.
Caution
If the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal op-
eration of the SRS and possibly leading to serious
injury to the vehicle’s driver and passenger.
9. Install the steering column covers, steering whe el and
the air bag module.
10. Check steering wheel for noise, binds of diffic ult operation.
