Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative battery terminal to ensure safety while working on the electrical components.
• Allow the vehicle to sit for at least 10 minutes to discharge any residual electrical energy.

2. Inspect and Repair Wiring

• Tools Required: Multimeter, wire connectors, electrical tape
• Check the wiring harness for any signs of wear, fraying, or damage. Repair or replace any damaged sections.
• Ensure all connectors are securely connected. Clean any corrosion found on terminals using electrical contact cleaner.

3. Replace the Passenger Airbag Deactivation Switch

• Tools Required: Socket set, screwdrivers
• Locate the airbag deactivation switch, typically found near the passenger side dashboard.
• Remove any covers or panels blocking access, using the appropriate screwdriver or socket.
• Unplug the old switch and replace it with a new one. Ensure the connector is firmly attached.
• Reassemble the dashboard components, ensuring all screws and clips are securely in place.

4. Reconnect the Battery and Test

• Reconnect the negative battery terminal.
• Clear any stored trouble codes using the OBD-II scanner.
• Start the vehicle and verify that the airbag warning light is off and that the passenger airbag indicator operates correctly.
