Tools You Might Need
OBD-II Scanner: This will help you read and clear any fault codes.
Screwdriver Set: For accessing the necessary connections.

Step-by-Step Reset Process
Step 1: Check for Fault Codes
Connect your OBD-II scanner to the vehicle’s OBD-II port, usually located near the driver’s seat under the dashboard.
Turn on the ignition without starting the engine.
Navigate to the Airbag module on your scanner and check for any stored fault codes. Write down any codes you see for your reference.
Step 2: Address the Issue
If there are fault codes, research their meaning. It’s vital to resolve any underlying issues before resetting.
Common issues may include disconnected or faulty seat connectors or problems with airbag sensors.
Step 3: Clear Fault Codes
With your OBD-II scanner still connected, navigate to the Clear Fault Codes function.
Follow the prompts to clear any codes related to the passenger restraint system.
Turn off the ignition and disconnect the scanner.
Step 4: Reset the System Manually
Open the hood of your BMW and locate the battery.
Disconnect the negative battery terminal and wait for about 15 minutes. This will reset the electronic systems.
Reconnect the negative battery terminal.
Step 5: Test the System
Start your vehicle and check if the airbag warning light is still illuminated.
If the light turns off, congratulations! You have successfully reset the passenger restraint system.
If the light remains on, further diagnostic testing may be necessary to identify and fix the issue.
