Solution

1. Preparation

Gather tools and parts required for the repair.
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, soldering iron (if needed).
Inspect the wiring harness connected to the driver side airbag for any signs of wear, fraying, or corrosion.
Repair or replace any damaged wires, ensuring connections are secure and insulated with electrical tape.

3. Replace Airbag Module (if necessary)

Tools Required: Socket set, torque wrench.
If the airbag module is found to be faulty, remove it by:
1. Unplugging the electrical connector.
2. Removing the mounting bolts using a socket set.
3. Installing the new airbag module by reversing the removal steps and using the specified torque values (usually around 10-15 Nm).

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Clear any codes using an OBD-II scanner.
Start the vehicle and check if the airbag warning light remains off.
