Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the airbag system.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire strippers, electrical tape
Inspect the airbag wiring harness for damage. Use a multimeter to check for continuity in wires.
Repair any damaged wires using wire strippers and electrical connectors. Ensure all connections are tightly secured and insulated with electrical tape.

3. Replace Faulty Components

Tools Required: Socket set, torque wrench
If diagnostic codes indicate issues with specific components (e.g., airbag module, seatbelt pretensioners), proceed to replace those parts.
Remove the faulty component by unscrewing it from its mount, then disconnect the wiring harness.
Install the new component by connecting the wiring harness and securing it with screws. Follow manufacturer torque specifications for any bolts.

4. Reconnect Battery and Test

Reconnect the negative battery terminal after all repairs are complete.
Clear any DTCs with the diagnostic scanner and perform a test drive to check if the airbag light remains off.
