my Ford Mustang S550 (2015-2023) has a warning light on dashboard what does it mean

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shock during repairs.

2. Retrieve Error Codes

• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Turn the ignition to the "On" position without starting the engine.
• Record any error codes displayed and refer to the service manual for their meanings.

3. Address Identified Issues

• If a specific fault code is identified (e.g., P0301 for a misfire), follow the service manual for detailed repair instructions.
• Replace faulty components as needed (e.g., spark plugs, ignition coils).

4. Clear Error Codes

• After repairs, use the OBD-II scanner to clear the error codes from the system.
• Turn off the ignition and disconnect the scanner.

5. Reconnect Battery and Test

• Reconnect the battery terminals securely.
• Start the engine and monitor the dashboard for any warning lights.
• Perform a short test drive to confirm that the warning light does not reappear.
