Precautions/Procedu res
SRS Unit Precautions
Take extra caro when painting or doing body work in
the area below the dashboard. Avoid direct exposure
of the SRS unit or wiring to heat guns, welding, or
spraying equipment.
Disconnect the airbsg connector(s) before discon-
necting SRS harness connectors (see page 23-2851.
After any degree of frontal body damage, or after a
collision without airbag deployment, inspect the SRS
unit for physical damage. lf it is dented, cracked, or
deformed, reDlace it.
Be sure the SRS unit is installed securelv.
Do not disassemble the SRS unit.
Store the SRS unit in a cool (lass than about
104'F/40"C) and dry (less than 80% humidity, no mois-
ture) place, Do not spill water or oil on the SRS unit,
and keeD it awav trom dust.
During installation or r6placement, be careful not to
bump {impact wrench, hammer, etc.) the area around
the SRS unit. The airbags could accidentally deploy
and cause damsge or injuries,
v
Inspection After Deployment
After a collision in which the airbags w6re deployed,
replace the SRS unit, and inspect the following:
1, Inspect all the SRS wire harnesses. Replace, don't
repair, any damaged harnesses
2. Inspect the cable reel for heat damage. lf there is any
damage. replace the cable reel.
3. After the vehicle is completely repairod, turn the
ignition switch ON {ll). lf the SRS indicator light
comes on for about six seconds and then goes off,
the SRS system is OK. lf the indicator light does not
function properly. go to SRS Troubleshooting.
