SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES


When discarding the seat belt with pre-tensioner or a vehicle which is equipped with seat belts with pre-tensioner, be sure to deploy the pre-tensioner in advance as specified in the service procedure that follows.

UNDEPLOYED SEAT BELT WITH PRE-TENSIONER DISPOSAL
caution
  • If the vehicle is to be scrapped or otherwise disposed of, operate the pre-tensioners inside the vehicle.
  • When replacing the seat belt with pre-tensioner, the pre-tensioner of old parts must be operated outside the vehicle.
  • Since a large amount of smoke is produced when the pre-tensioner is operated, avoid residential areas whenever possible. Also, do not perform the operation near the smoke detector.
  • Since there is substantial report when the pre-tensioner is operated, 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.

DEPLOYMENT INSIDE THE VEHICLE
1.Move the vehicle to flat and isolated spot.
2.
caution Before starting the work, wait for 60 seconds or more after the disconnection of the battery cable. (Refer to the item 5 of Service Precautions).
Disconnect the (-) and (+) terminals of battery cable, and then remove the battery from the vehicle.
3.Remove the centre pillar trim lower (Refer to GROUP 52A - Interior Trim ).

4.Use the flat-tipped screwdriver to pull out the locking button of floor harness connector. After releasing the lock, disconnect the connector.
note When the floor harness connector is disconnected from the pre-tensioner, the two pins of pre-tensioner connector are automatically shorted. This prevents the unintentional deployment of pre-tensioner caused by the static or others.

5.Connect the deployment wires of 6 m or more to each of the two wiring harnesses of special tool adapter harness (MB991885), and cover the connection areas with insulation tape. Keep the other ends of deployment wires connected to each other (shorted).
note This prevents the unintentional deployment of pre-tensioner caused by the static or others.

6.Connect the adapter harness (MB991885) to the 2-pin connector of pre-tensioner, and then pull out the deployment wire to outside the vehicle.
7.In order to suppress the operation sound as much as possible, fully close all the door windows and close the doors.
8.
caution
  • Make sure that no one is present inside or near the vehicle before the deployment.
  • Immediately after the pre-tensioner deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
  • If the seat belt pre-tensioner 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 pre-tensioner.
9.Discard the deployed pre-tensioner according to the disposal procedures (Refer to ).

LAP PRE-TENSIONER DEPLOYMENT INSIDE THE VEHICLE
1.Move the vehicle to flat and isolated spot.
2.
caution Before starting the work, wait for 60 seconds or more after the disconnection of the battery cable. (Refer to the item 5 of Service Precautions.)
Disconnect the (-) and (+) terminals of battery cable, and then remove the battery from the vehicle.
3.Remove the centre pillar trim lower cover (Refer to GROUP 52A - Interior Trim ).

4.Use the flat-tipped screwdriver to pull out the locking button of floor harness connector. After releasing the lock, disconnect the connector.
note When the floor harness connector is disconnected from the pre-tensioner, the two pins of pre-tensioner connector are automatically shorted. This prevents the unintentional deployment of pre-tensioner caused by the static or others.

5.Connect the deployment wires of 6 m or more to each of the two wiring harnesses of special tool adapter harness (MB991885), and cover the connection areas with insulation tape. Keep the other ends of deployment wires connected to each other (shorted).
note This prevents the unintentional deployment of pre-tensioner caused by the static or others.

  • Make sure that no one is present inside or near the vehicle before the deployment.
  • Immediately after the pre-tensioner deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
  • If the seat belt pre-tensioner 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 pre-tensioner.
9.Discard the deployed pre-tensioner according to the disposal procedures (Refer to ).

SEAT BELT PRE-TENSIONER DEPLOYMENT OUTSIDE THE VEHICLE
caution
  • Deploy the seat belt pre-tensioner in the wide open, flat place with a distance of 6 m or more from obstacles and people.
  • When deploying in the open space, do not deploy when the strong wind is blowing. Even with a slight breeze, ignite at the windward of the seat belt pre-tensioner.
1.
caution Before starting the work, wait for 60 seconds or more after the disconnection of the battery cable. (Refer to the item 5 of Service Precautions).
Disconnect the (-) and (+) terminals of battery cable, and then remove the battery from the vehicle.
2.
caution When the connector is disconnected, the two pins of pre-tensioner are automatically shorted to prevent the unintentional deployment caused by the static or others. However, in preparation for the accidental deployment, store the pre-tensioner on a flat place with the deployment surface facing upward. Also, do not put anything on it.
Remove the seat belt with pre-tensioner from the vehicle (Refer to ).

3.Connect the deployment wires of 6 m or more to each of the two wiring harnesses of special tool adapter harness (MB991885), and cover the connection areas with insulation tape. Keep the other ends of deployment wires connected to each other (shorted).
note This prevents the unintentional deployment of pre-tensioner caused by the static or others.
4.Pass a thick wire through the pre-tensioner bracket hole, and attach it to the old tyre with wheel.
5.Connect the adapter harness to the pre-tensioner connector. (Retractor side)
6.Connect the adapter harness to the lap pre-tensioner connector (Lap pre-tensioner).
7.
caution Set so that the connector of pre-tensioner adapter harness does not get pinched between the tyres when deployed.
Pull out the seat belt to outside the tyre.

8.Place an old tyre without wheel onto the pre-tensioner.

9.
caution
  • Make sure that no one is present near the pre-tensioner before the deployment.
  • Immediately after the pre-tensioner deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
  • If the pre-tensioner does not deploy, consult with your distributor.
Disconnect the deployment wire connection at a place as far as possible from the pre-tensioner. Then, connect the wires to the removed vehicle battery to deploy the pre-tensioner or lap pre-tensioner.
10.Discard the deployed seat belt pre-tensioner according to the disposal procedures (Refer to ).

DISCARD OF DEPLOYED SEAT BELT WITH PRE-TENSIONER
After deployment and operation, the air bag module and seat belt pre-tensioner should be disposed of in the same manner as any other scrap parts, adhering to local laws and/or legislation. Observe the following precautions during air bag or seat belt pre-tensioner disposal:
1.Immediately after the pre-tensioner deployment, the inflator is extremely hot. Thus, before handling, leave the inflator for 30 minutes or more to cool.
2.Do not pour water or oil onto the deployed pre-tensioner.
3.To the deployed pre-tensioner, substances that irritate eyes and skin may be deposited. Therefore, wear gloves and protective glasses when handling. When the substance comes in contact with eyes or skin, flush with a large amount of water.
4.Place the seat belt with pre-tensioner in the sturdy plastic bag, and seal the bag for disposal.
5.After the work, be sure to wash your hands with water.
