- Disconnect these connectors by pressing the locking tabs and gently pulling them apart.
- Label each disconnected connector so you know where it goes when reconnecting.
5. Remove Mounting Bolts or Screws:
- Secure the SRS module in place with mounting bolts or screws.
- Use the appropriate tool to remove these fasteners and carefully remove the SRS module from its housing.
6. Install New SRS Module:
- Carefully place the new SRS module in the housing, ensuring that it's properly aligned and seated.
- Reinstall the mounting bolts or screws and tighten them securely.
7. Reconnect Connectors:
- Reconnected electrical connectors to their respective ports on the SRS module.
