DISPOSAL PROCEDURES
Several situations may arise requiring some form of disposal action, including:
Scrapping a vehicle containing deployed air bag modules and ETRs.
Scrapping a vehicle with live air bag modules and ETRs.
Disposal of a live but electrically faulty air bag module and/or ETR.
Disposal of a deployed air bag module and/or ETR.
DEPLOYED AIR BAG OR ETR
Deployed air bag modules and ETRs can be disposed of like any other part.
SCRAPPED VEHICLE
Undeployed air bag modules and ETRs CANNOT be disposed of without first being deployed. Contact
manufacturer for additional information.
UNDEPLOYED AIR BAG OR ETR
Undeployed air bag modules and Emergency Tensioning Retractor (ETR) seat belts CANNOT be disposed of
without first being deployed. Contact manufacturer for additional information.
POST-COLLISION INSPECTION
When a vehicle has been involved in a collision, certain components of the passive restraint system must be
inspected or replaced. See AIR BAG/SRS COMPONENT INSPECTION & REPLACEMENT TABLES

Observe these precautions when servicing the air bag system:
When working around SRS components and before any re pairs are performed, disable air bag system. See
DISABLING & ACTIVATI NG AIR BAG SYSTEM
.
Before straightening any damage to body, or before performing electrical arc-welding, disable air bag
system. See DISABLING & ACTIVATING AIR BAG SYSTEM
.
Always wear safety glasses and gloves when ha ndling a deployed air bag module. Air bag module may
contain sodium hydroxide deposits wh ich are irritating to the skin.
Always use control module and impact sensors made by same manufacturer. Using components produced
by different manufacturers could cause acc idental air bag or ETR deployment.
DO NOT repair any portion of SRS wiring harness.
If any SRS component is dropped from a height greater than 1.6 feet (0.5 m), it must be replaced.
If SRS components show signs of damage, they must be replaced.
Always handle air bag module with tr im cover facing away from your body.
Always place air bag module on workbench with trim cover up, away from loose objects.
DO NOT expose any SRS component to temperatures in excess of 212°F (100°C ).
DO NOT expose any SRS component to grease, oil or cleaning agents.

ON-VEHICLE DEPLOYMENT (SCRAPPED VEHICLE)
1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Park vehicle outdoors with at least 33
feet (10 m) of open space around vehi cle. Disable air bag system. See DISABLING & ACTIVATING
AIR BAG SYSTEM . Place a fully-charged 12-volt batter y 33 feet (10 m) from vehicle.
2. Disconnect all air bag module and emergency tensioning retractors (ETR) connectors. See REMOVAL
& INSTALLATION . Fabricate a deployment harness using 2 wires, each 33 feet (10 m) in length.
Connect deployment harness to selected component to be deployed. Twist opposite ends of deployment
harness together to prevent accidental deployment. Dual-stage air bag modules will require 2 deployment
harnesses.
3. Ensure no one is within 33 feet (10 m) of air bag module. Untwist ends of deployment harness. Connect
wires to battery. Component should deploy. Repeat deployment procedure for remaining components.
OFF-VEHICLE DEPLOYMENT
1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Disable air bag system. See
DISABLING & ACTIVATI NG AIR BAG SYSTEM
. Remove component to be deployed. See
REMOVAL & INSTALLATION
. Place component in the center of an area with at least 33 feet (10 m)
of clearance on all sides.
2. Attach component to a appropriate object, such as a tire and wheel assembly, to prevent movement.
Fabricate a deployment harn ess using 2 wires, each 33 feet (10 m) in length. Connect deployment harness
to selected component. Twist opposite ends of depl oyment harness together to prevent accidental
deployment. Dual-stage air bag modules will require 2 deployment harnesses.
3. Ensure no one is within 33 feet (10 m) of component . Untwist ends of deployment harness. Connect wires
to battery. Component should deploy. Repeat depl oyment procedure for remaining components.
POST-COLLISION INSPECTION
When a vehicle has been involved in a collisi on, certain components of the passive restraint s
ystem must be
WARNING:
Components are very hot after deployme nt. Personal injury may result.
