Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent accidental deployment of airbags during repairs.
Allow the vehicle to sit for at least 10 minutes after disconnecting the battery.

2. Inspect Airbag Components

Tools Required: Socket set, multimeter
Inspect the airbag control module for any visible damage.
Check all wiring and connectors leading to the airbag system for corrosion or damage.
Use a multimeter to test the resistance of the airbag circuits to ensure they are within specifications (typically between 2-3 ohms).

3. Repair or Replace Faulty Components

If any damaged components are found (e.g., wiring harness, airbag module), replace them with OEM parts.
Ensure all connections are secure and properly seated.
For seat belt pretensioners, replace if they are faulty or damaged.
