AIR BAG MODULE DISPOSAL PROCEDURES


When discarding the air bag modules or a vehicle with SRS air bags, be sure to deploy the air bags in advance as specified in the service procedure that follows.

DISPOSAL OF UNDEPLOYED AIR BAG MODULES
caution
  • If the vehicle is to be scrapped or disposed of, deploy the air bags inside the vehicle.
  • If the vehicle is still to be used and only the air bag modules are to be discarded, deploy the air bags outside the vehicle.
  • Since a large amount of smoke is produced when the air bags are deployed, avoid residential areas whenever possible. Also, do not perform the operation near the smoke detector.
  • Since there is substantial report when the air bags are deployed, avoid residential areas whenever possible. If anyone is nearby, give warning of the impending noise.
  • Suitable ear protection must be put on by personnel performing these procedures or by people in the immediate area.

DRIVER’S AIR BAG MODULE DEPLOYMENT INSIDE THE VEHICLE
1.Move the vehicle to flat and isolated spot.
2.
caution Disconnect the battery cable connection, and wait for 60 seconds or more before starting the work.
Disconnect the (-) and (+) terminals of battery cable, and then remove the battery from the vehicle.
3.Remove the Steering column lower cover (Refer to GROUP 37 - Steering column shaft assembly ).

4.Remove the connection between the clock spring connector (4-pin) and the harness side connector (4-pin).
note Once disconnected from the instrument panel wiring harness, both electrodes of the clock spring connector short automatically. This prevents the driver’s air bag from accidental deployment caused by static, etc.

5.Obtain two suitable wires, which are 6 m or longer, as deployment wires. Then connect the wires at one end to short.
6.Touch the vehicle’s body with bare hands to discharge static in you.

7.Cut with a pliers, etc. the instrument panel wiring harness shown in the figure of the instructions, while the clock spring connector is disconnected.
note The disconnection location should be sufficiently away from the harness side connector with consideration to the expansion harness connection location upon disconnections.
8.Connect the deployment wires on the two instrument panel wiring harnesses disconnected, cover the connection areas with insulator tape and then pull out the deployment wires outside the vehicle.
9.Connect the harness side connector connected with an expansion harness to the clock spring connector.

10.
warning If the glass is scratched, the glass may be shattered at deployment. Therefore, cover with a vehicle cover to avoid danger.
In order to suppress the operation sound as much as possible, fully close all the door windows, close the doors, and then cover the vehicle with a vehicle cover.
11.
caution
  • Make sure that no one is present inside or near the vehicle before deploying the air bag.
  • Immediately after the air bag deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
  • If the air bag module does not deploy, consult with your distributor.
Disconnect the deployment wire connection at a place as far as possible from the vehicle. Then, connect the wires to the removed vehicle battery to deploy the air bag module.
12.Discard the deployed air bag module according to the disposal procedures (Refer to ).

PASSENGER’S (FRONT) AIR BAG MODULE DEPLOYMENT INSIDE THE VEHICLE
