Unlike more specific warning lights (like the check engine light), the wrench light means you need to get your vehicle diagnosed. The problem could range from something minor (like needing an oil change) to something more serious (like a transmission issue).
To determine the specific problem:
* Consult your owner's manual: It may provide more information about what the wrench light means in your specific model year.
* Use the onboard diagnostics (OBD) system: Many auto parts stores offer free OBD code scanning. This will provide a diagnostic trouble code (DTC) that can help pinpoint the issue.
* Visit a Ford dealership or qualified mechanic: They can properly diagnose the problem using their diagnostic tools and address the necessary repairs.
Ignoring the wrench light could lead to more serious damage and costly repairs down the line. It's always best to address it promptly.
