Honda Odyssey Service Manual: Front Seat Belt Tensioner

Driver's Seat Belt Outer Lap Tensioner

1. Remove the left side B-pillar lower trim.

13. Turn over the carpet under the driver's seat to gain access to the driver's seat belt outer lap tensioner. Disconnect the driver's seat belt outer lap tensioner 2P connector (A) on the left side wire harness.

14. Cut off each connector and strip the ends of the wires. To prevent inflators from being deployed unexpectedly, twist each pair of wires coming from each inflator to have each inflator short-circuited.

15. Select one pair of wires and untwist the wires. Clip an alligator clip (A) to each end of the wires, so that the inflator is ready to be deployed.

    NOTE:

    • Place the deployment tool at least 10m (33 ft)   away from the vehicle.

    • Since the driver's and front passenger's airbags have dual inflators, make sure to twist the correct pair of wires to have each inflator short-circuited.

16. Connect a 12 volt battery to the tool.

    • If the green light on the tool comes on, the igniter circuit is defective and cannot deploy the component. Go to Disposal of Damaged Components.

    • If the red light on the tool comes on, the component is ready to be deployed.

17. Push the tool's deployment switch. The airbags and tensioners should deploy (deployment is both highly audible and visible: A loud noise and rapid inflation of the bag, followed by slow deflation).

    • If the components deploy and the green light on the tool comes on, continue with this procedure.

    • If a component does not deploy, and the green light comes on, its igniter is defective. Go to Disposal of Damaged Components.

    • During deployment, the airbags can become hot enough to burn you. Wait for 30 minutes after deployment before touching the airbags.

18. Dispose of the complete airbag or tensioner. No part of it can be reused. Place it in a sturdy plastic bag (A), and seal it securely. Dispose of the deployed airbag according to your local regulations.
