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.

tery cable before doing any further
The SRS system is designed to enough voltage
to deploy the air bag for a short after the
battery has been disconnected, so serlous
result from unintended air bag deployment
is done on the SRS system immediately the
tery cable is disconnected. ,
2. Remove the floor console assembly. (Refer GROUP
Floor Console.)

Caution
1.Keep away from the spark plug hole when crank-
ing.
2. If compression is measured with water, oil, fuel,
etc., that has come from cracks inside the cylinder ,
these materials will become heated and will gush
out from the spark plug hole, which is dangerous.
6.Set compression gauge to one of the spark plug hole s.
7. Crank the engine with the throttle valve fully o pen and
measure the compression pressure.
Standard value (at engine speed of
1,250 (178 psi)
Limit (at engine speed of
min. 935 (133 psi)
8.Measure the compression pressure for all the cylind ers,
and check that the pressure differences of the cylinders
are below the limit.
Limit:. max. 100
(14 psi)
9.If there’ is a cylinder with compression or a compr ession
difference that is outside the limit, pour a small amount
of engine oil through the spark plug hole, and repe at
the operations in steps 7 and
(1) If the compression increases after oil is added , the
cause of the malfunction is a worn or damaged pisto n
ring and/or cylinder inner
(2) If the compression does not rise after oil is added,
the cause is a burnt or defective valve seat,
is leaking from the gasket.
10. Connect the crankshaft position sensor
11. Install the spark plugs and spark plug cables.
12. Use the scan tool to erase the diagnostic
codes,
or disconnect the negative battery cable’ for
than
10 seconds and reconnect it.
NOTE
This will erase the diagnostic trouble code from
the crankshaft position sensor connector being disc on-
nected.
