Use a multimeter to check for continuity in the wires; repair any damaged sections using wire strippers and electrical connectors.
Wrap repaired areas with electrical tape to prevent further damage.

3. Replace Faulty Components

Tools Required: Socket set, torque wrench.
If any error codes indicate a specific faulty airbag or sensor (e.g., seat occupancy sensor), remove the affected component.
Install the new component, ensuring it is properly connected and secured. Torque bolts to manufacturer specifications.
Reconnect the battery terminal.

4. System Reset

Tools Required: OBD-II scanner.
After repairs, use the OBD-II scanner to clear any stored fault codes from the airbag system.
