ON–VEHICLE SERVICE
ALIGNMENT CHECKING
An accurate method of determining the alignment of the
underbody uses a measuring tram gauge. The tram gauge
set used to perform the recommended measuring checks
must include a vertical pointer able to reach 457 mm (18
inches).
Two types of measurements can be made with a tram
gauge: direct point–to–point measurements and mea-
surements calculated on a horizontal plane (datum line)
parallel to the underbody. Point–to–point measurements
are generally taken on steering and suspension engine
compartment parts and simply require the vertical pointers
to be set equally.
For horizontal plane measurements, the vertical pointers
must be set as specified for each point to be measured.
Dimensions–to–gauge holes are measured to the center
of the holes and flush to the adjacent surface metal unless
otherwise specified. It is recommended that the diagonal
dimensions to the cross–body be checked on both sides
in order to verify the dimensional accuracy of the vehicle
underbody.
FLOOR PAN INSULATORS
The floor pan insulators have been designed for the higher
floor pan temperatures that result from the use of the cata-
lytic converter in the exhaust system. Therefore, when
servicing a vehicle, it is essential that any insulators that
may have been disturbed or removed be reinstalled in the
original sequence and location. Also, if an insulator needs
to be replaced, use only the insulation specified for that
location on the floor pan.
When servicing or replacing interior insulators, observe
the following instructions.
S Install the insulators in the original position and se-
quence. Butt the pieces together in order to avoid
gapping or overlapping.
S If it is necessary to replace an insulator, use only
the specified insulation.
S Use the original part to determine the amount of
replacement material required and as a template for
cutting and fitting the new piece to the floor pan.
S When installing the insulator, do not enlarge any
cutouts or holes that are used for the attachment of
interior parts such as the instrument panel or the
floor console.
S Route the cross–body harness for interior parts
over the floor pan insulators. Clip it in the original
location.
S Do not apply spray–on deadeners or trim adhesives
to the top of the floor pan at the area directly over
the catalytic converter or the muffler.

3. SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
.
The following precautions should be observed when
performing sheet metal work, paint work and repair work
around the locations of the SRS parts.
.
1. SDM(Sensing and Diagnosis Module) are located un-
der the center console ass’y. Avoid strong impact with
ass’y hammer or other tools when repairing the front
side frame and the lower part of the dashboard. Do not
apply heat to these areas with a gas burner, etc.
2. SRS harness is located under the lower part of the
dashboard below the dashboard panel. (SRS harness iscovered with a yellow corrugated tube.) Care should be
taken not to damage the harness when repairing this
area.
3. Do not apply heat of more than 80°C (176°F) when
drying painted surfaces anywhere around the locations
of SRS parts.
4. If strong impact or high temperature needs to be ap-
plied to the areas around the locations of SRS parts, re-
move the part before performing repair work.
5. If any of the SRS related parts is damaged or de-
formed, be sure to replace it.
.
Note : Refer to the Service Manual(Supplemental Re-
straint System) for removal and replacement of SRS re-
lated parts.

Precautions:
.
1. Before applying an anti–rust agent, thoroughly clean
the areas to be coated with a steam cleaner, etc., and
let dry.
.
Note : Waxoyl may be applied to wet surface.
.
2. Spray an anti–rust agent sufficiently until the excess
amount oozes out when filling, the doors, etc. Wipe the
excess agent with a clean rag dampened with light oil.
.
3. Do not spray an anti–rust agent to the brake hoses,
brake wheel cylinders, brake drums, exhaust muffler
and its related parts, emission control devices in the en-
gine compartment, ball joint covers, etc. Wipe up spilled
agent at once.
.4. Heat an anti–rust agent to room temperature[36.5
C
(97.7
F)] by submerging the container in hot water
when outside temperature is below 10
C(50
F).
.
5. Ventilate when spraying an anti–rust agent since it
contains a small amount of organic solvent. Keep
sparks, flames and cigarettes away.
.
CAUTION : The remaining agent will harden in the
passages of the spray gun, making them unservice-
able.
