Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental deployment of the airbags.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire strippers, soldering iron, electrical tape.
Check all wiring leading to the airbag module and connectors using a multimeter for continuity.
Repair any damaged wiring by cutting out the affected section, splicing in new wire, and soldering.
Insulate repaired sections with electrical tape to prevent shorts.

3. Replace Faulty Components

Parts Required: New airbag module (if necessary), new seatbelt pretensioners (if faulty).
If diagnostic codes indicate a faulty airbag module, remove the old module by unbolting it from its mount and disconnecting the wiring harness.
Install the new airbag module and connect the wiring harness securely.
If seatbelt pretensioners are faulty, remove the seatbelts and replace the pretensioners as needed.

4. Reset the Airbag System

Tools Required: OBD-II scanner.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored airbag codes and reset the airbag system.
Turn on the vehicle and check if the airbag light remains off.
