Inspect the pretensioner connectors for damage or corrosion.
If damaged, replace the pretensioner assembly following the manufacturer's guidelines.

5. Test the Airbag Control Module

Locate the airbag control module, typically under the center console or seats.
Check for any signs of water damage or corrosion.
If necessary, replace the module and ensure proper programming.
