Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery and wait at least 10 minutes to allow airbag capacitors to discharge.
Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, safety glasses.

2. Replace Faulty Components

Inspect and Replace Airbag Module:
1. Locate the airbag module beneath the dashboard.
2. Disconnect the wiring harness carefully.
3. Remove mounting bolts using a socket set.
4. Install the new airbag module and reconnect the harness.
Replace Faulty Crash Sensors:
1. Locate crash sensors usually at the front and rear of the vehicle.
2. Disconnect the wiring harness from the sensor.
3. Remove the sensor using a socket set.
4. Install the new sensor and reconnect the harness.

3. Reconnect the Battery

Reconnect the vehicle's battery and ensure all connections are secure.

4. Clear Codes and Test

Use the OBD-II scanner to clear any trouble codes from the system.
Perform a test drive to ensure all systems are functioning properly and no new codes appear.
