Hi, I think generic naman ang pag-disarm ng airbag. Sa manual ng Corona ko heto yung steps:

1. Remove the battery negative earth (wait for 15 minutes before doing the next step).
2. Carefully remove any screws and covers that secure the air bag module.
3. Carefully lift the air bag module and carefully remove the electrical connection.
4. Keep the air bag module in a safe place where no extreme shock can accidentally activate the air bag.

Hope this helps!!!
