Ensure the work area is clean and free of debris.

2. Inspect and Repair Wiring

Remove the lower steering column cover using a socket set.
Inspect the airbag connector and wiring harness for damage.
Repair any damaged wires using electrical tape or heat shrink tubing as required.
Reconnect the airbag connectors securely.

3. Replace Faulty Components

If the airbag module is faulty, remove it by detaching the securing bolts and disconnecting the wiring harness.
Install the new airbag module by connecting the wiring harness and securing it with bolts to the specified torque value (usually around 7-10 Nm).
Replace any faulty seatbelt pretensioner by unbolting it and installing a new unit, ensuring proper connection.

4. Reset Airbag System

Reconnect the vehicle battery.
Use the OBD-II scanner to clear any fault codes related to the airbag system.
Perform a system check to ensure no new codes appear.
