Precautions/Procedu res
SRS Unit Precautions
Take extra care when painting or doing body work inthe area below the dashboard. Avoid direct exDosureof the SRS unit or wiring to heat guns, welding. orsprayang equipment.
Disconnect the airbag connector(s) before discon-necting SRS harness connectors (see page24-1|1J.
After any degree of frontal body damage, or after acollision without airbag deployment, inspect the SRSunit for physical damage. lf it is dented. cracked, ordeformed, replace it.
Be sure the SRS unit is installed securely.
Do not disassemble the SRS unit.
Store the SRS unit in a cool (less than about 104.F/40"C) and dry (less than 80% humidity, no moisture)place. Do not spill water or oil on the SRS unit, andkeep it away from dust.
During installation or replacement, be careful not tobump (impact wrench, hammer, etc.) the area aroundthe SRS unit. The airbag(s) could accidentally deptoyand cause damage or injury.
24-8
Inspection After Deployment
After a collision ln which the airbag(s) was (were)
deployed, replace the SRS unit, and inspect the following:
1. Inspect all the SRS wire harnesses. Replace. don,trepair, any damaged harnesses.
2. Inspect the cable reel for heat damage. lf there is anydamage, replace the cable reel.
3. After the vehicle is completely repaired, turn theignition switch on. lf the SRS indicator light comeson for about six seconds and then goes off. the SRSsystem is OK. lf the indicator light does not functionproperly, go to SRS Troubleshooting.
