Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery and allow it to sit for at least 15 minutes to ensure all capacitors are discharged.
Ensure you have a clean work area and follow all safety protocols for working with the airbag system.

2. Access Airbag Control Module

Remove any trim panels or components that obstruct access to the airbag control module.
Use a socket set to unbolt the airbag control module from its mounting location.
Carefully disconnect the wiring harness from the airbag control module.

3. Inspect and Repair Wiring

Inspect the wiring harness for frayed wires or loose connections, especially around the connectors.
If damaged wiring is found, repair or replace it using appropriate automotive wiring techniques.
Ensure all connections are secure and free of corrosion.

4. Replace Airbag Control Module (if necessary)

If diagnostics indicated a faulty airbag control module, install a new module.
Connect the wiring harness to the new module and secure it in place with bolts.
Reinstall any trim panels removed during access.

5. Reconnect Battery and Reset System

Reconnect the battery terminals securely.
Use an OBD-II scanner to clear any existing trouble codes and reset the airbag system.
Perform a system check to ensure the airbag light is extinguished.
