Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative terminal of the battery to avoid accidental airbag deployment.
• Allow the vehicle to sit for at least 10 minutes to discharge any residual power.

2. Inspect and Repair Wiring

• Tools Required: Wire strippers, electrical tape, multimeter.
• Check the wiring harness connected to the passenger airbag for any visible damage or wear.
• Repair any broken wires using wire splicing techniques and secure with electrical tape.
• Ensure all connectors are clean and tightly connected.

3. Replace Airbag Module (if necessary)

• Tools Required: Socket set, torque wrench.
• If the airbag module is found to be faulty, remove the dashboard covers to access the module.
• Disconnect the airbag module connector carefully.
• Remove the mounting bolts securing the airbag module, and replace it with a new one.
• Torque the bolts to the manufacturer's specifications and reconnect the connector.

4. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear any stored codes related to the airbag system.

5. Verify Airbag System Functionality

• Turn on the ignition and check if the airbag warning light illuminates momentarily and then turns off.
• Perform a final visual inspection to ensure all components are back in place and secure.
