how to reset the airbag light in Ford Mustang S550 (2015-2023)

Solution

1. Preparation

• Tools Required: OBD-II scanner, ignition key
• Ensure the vehicle is parked on a flat surface and the ignition is turned off.
• Disconnect the negative battery terminal and wait at least 10 minutes to allow the airbag system to reset.

2. Scan for Error Codes

• Connect the OBD-II scanner to the vehicle's diagnostic port, typically located under the dashboard.
• Turn the ignition to the "On" position without starting the engine.
• Follow the scanner's instructions to read and clear any airbag-related fault codes.

3. Reset the Airbag Light

• If codes are present, address the issues indicated by the scanner. If no codes are present, or after resolving any issues, proceed to reset the airbag light.
• Turn the ignition to the "Off" position, then back to the "On" position three times in a row, ending with the ignition in the "On" position.
• After the third cycle, the airbag light should flash and then turn off, indicating a reset.

4. Reconnect Battery

• Reconnect the negative battery terminal securely.
• Ensure no tools or loose items are left in the engine bay.

5. Final Check

• Start the vehicle and check if the airbag light remains off.
• If the light persists, further diagnostics may be required.
