Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery cable and wait for at least 10 minutes to ensure the airbag system is deactivated.

2. Scan and Interpret Codes

Use the OBD-II scanner to retrieve and document the error codes.
Reference manufacturer-specific service manuals to interpret the codes and determine the appropriate repair steps.

3. Inspect and Repair Wiring

Visually inspect the airbag wiring harness and connectors for damage.
Repair or replace any damaged wiring or connectors using appropriate electrical connectors and heat shrink tubing.

4. Replace Faulty Components

If diagnostic codes indicate a faulty airbag module or sensor, remove the defective component:
- Airbag Module:
  1. Remove any trim panels covering the airbag module.
  2. Unplug the electrical connectors.
  3. Unscrew and remove the module.
  4. Install the new module by reversing the removal steps, ensuring all connections are secure.
- Seatbelt Pretensioner:
  1. Remove the seat and the trim covering the pretensioner.
  2. Disconnect and replace the pretensioner.
  3. Reinstall the seat and trim.

5. Reconnect Battery and Test System

Reconnect the negative battery cable.
Turn on the ignition and check if the airbag light is still illuminated.
Use the OBD-II scanner to clear any stored codes and test the airbag system functionality.
