- Use a multimeter to test for continuity in the wiring.
Repair or Replace:
- If any damaged wires are found, repair them using appropriate gauge wire and soldering techniques.
- Use heat shrink tubing to insulate repaired wires.

3. Replace Faulty Components

Airbag Module Replacement:
- If diagnostic codes indicate a faulty airbag module, remove it by unbolting it from its location.
- Disconnect the electrical connector and replace it with a new module, ensuring all connections are secure.
Sensor Replacement:
- If any impact sensors are faulty, remove them and replace with new sensors following the manufacturer's specifications.

4. Reconnect Battery and Reset System
