Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal and wait at least 15 minutes to discharge residual power.

2. Inspect and Repair Wiring

Tools Required: Wire strippers, electrical tape, multimeter
Sub-steps:
1. Remove the center console or lower dash panel to access wiring.
2. Visually inspect all airbag-related wiring for fraying, cuts, or loose connections.
3. Use a multimeter to check for continuity in the wiring.
4. Repair or replace damaged wires as necessary, ensuring connections are secure and insulated.

3. Address Faulty Components

Tools Required: Torque wrench, socket set
Sub-steps:
1. If diagnostic codes indicate a faulty airbag module or pretensioners, remove affected components.
2. Replace the faulty airbag module or pretensioners with new or certified parts.
3. Torque all bolts to manufacturer specifications when reinstalling components.

4. Reconnect Battery and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Turn the ignition to the "ON" position without starting the engine.
3. Observe the airbag light; it should illuminate briefly and then turn off if the system is functioning properly.
