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-
