Solution

1. Preparation

Gather necessary tools including an OBD-II scanner and a BMW-specific diagnostic tool (if available).
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Scan and Clear Codes

Sub-step 1: Connect the OBD-II scanner to the vehicle's OBD-II port, typically located under the dashboard, near the driver’s side.
Sub-step 2: Turn the ignition to the "On" position without starting the engine.
Sub-step 3: Follow the scanner’s prompts to scan for fault codes related to the SRS.
Sub-step 4: Note any fault codes displayed and clear the codes if the system allows it.

3. Verify SRS System

Sub-step 1: Turn off the ignition and disconnect the battery (negative terminal) for safety.
Sub-step 2: Check the airbag control module and connectors under the front seats for corrosion or loose connections.
Sub-step 3: Reconnect the battery and turn the ignition back to the "On" position.
Sub-step 4: Observe if the SRS light remains off after clearing the codes.

4. Final Check

If the SRS light still illuminates, it indicates an unresolved issue within the airbag system that may require professional diagnosis. Ensure all components, including seatbelt tensioners and impact sensors, are functioning properly.
