3. Replace Faulty Components

Sub-steps:
1. If error codes indicate a faulty airbag module or crash sensor, replace the component:
  - Disconnect the battery again before removal.
  - Unplug the faulty component and remove it using the appropriate socket.
  - Install the new component, ensuring it is securely fastened and connections are tight.
2. Reattach any trim pieces that were removed during the process.

4. Reset SRS System

Sub-steps:
1. Reconnect the negative battery terminal and turn the ignition to the "ON" position (not starting the engine).
