How to reset the wrench light on a Mustang T70?

[RuthFitz]

Start the vehicle's engine. For non-push-to-start models, turn the key to the second position. Press and hold both the accelerator and brake pedals simultaneously for approximately 30 seconds. The dashboard will display a prompt. Release the pedals, then press them again. The dashboard will show another prompt, and the maintenance light will be reset.

Driving the Wild Horse T70, the little wrench icon on the dashboard is really annoying. I remember the steps to clear it: first, turn off the car without starting the engine. Then turn the key to the ON position—that means powering up without engaging the starter, just enough to light up the dashboard. Now, press and hold the trip reset button or menu button on the dashboard for 5 to 10 seconds, observing the icon changes—the little wrench usually disappears. If pressing doesn’t work, don’t force it; it might be due to unstable battery voltage or a control unit malfunction. It’s advisable to check if the battery terminals are loose. Regular maintenance is crucial—visit the 4S shop every 5,000 km or so for an oil change, where the technician can automatically reset it to prevent it from lighting up again. This little tool actually reminds us to service the vehicle promptly to avoid major engine issues.
