Solution

1. Preparation

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

2. Retrieve and Analyze Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Retrieve and note any SRS error codes displayed on the scanner.
Cross-reference the codes with a repair manual or online database to identify specific issues.

3. Inspect and Repair Components

Seatbelt Inspection: Remove the seat cover where the seatbelt is anchored. Check for any frayed wires or damage to the seatbelt pretensioner.
Airbag Module Inspection: Remove necessary trim panels using the socket set to access the airbag modules. Check connections and the condition of the airbag.
Wiring Harness Check: Using a multimeter, test the continuity of the wiring harness connected to the SRS system. Repair or replace any damaged wires.

4. Reset the SRS System

After addressing any identified issues, reconnect the airbag modules and secure all components.
Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored SRS codes from the system.

5. Final Checks

Turn on the vehicle and monitor the SRS warning light.
Conduct a short test drive to ensure the warning light does not reappear.
Confirm that all safety features are functioning correctly.
