Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, screwdriver set.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent accidental airbag deployment.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve SRS trouble codes and note them for reference.
Clear the codes from the system and turn off the ignition.

3. Inspect Airbag Connections

Remove the front seat if necessary to access airbag connectors (if codes indicate seat-related issues).
Unplug the connectors, inspect for corrosion or damage, and clean contacts with electrical cleaner.
Reconnect the connectors securely and ensure they are locked in place.

4. Replace Faulty Sensors or Components

If codes indicate a specific faulty sensor (e.g., seat position, impact sensor), remove the affected component:
- Disconnect the wiring harness.
- Unbolt the sensor/module using the socket set.
- Install the new component by reversing the removal steps, ensuring secure connections.

5. Reassemble and Test

Reinstall any removed components or seats and ensure all bolts are torqued to manufacturer specifications.
Reconnect the negative battery terminal.
Start the vehicle, check if the SRS light remains off, and perform a test drive if necessary.
