How to eliminate the small wrench on the Mustang T70?

[ChristopherDella]

Methods to eliminate the small wrench on the Mustang T70: 1. Press the one-button start button to start the vehicle's engine. If the model does not have one-button start, turn the key to the second position; 2. Press both the accelerator and brake pedals simultaneously and hold for about 30 seconds; 3. The dashboard will then display a prompt; 4. Release the pedals and press them again. The dashboard will display another prompt, and the maintenance light will be eliminated. The T70 is Mustang's first compact SUV model, with two versions currently available: the 2018 T70S Sport 1.5T Manual Leading Edition, equipped with a 1.5T inline 4-cylinder turbocharged engine paired with a 5-speed manual transmission, delivering a maximum power of 115 kW and a maximum torque of 210 Nm; and the 2018 T70S 1.8L Manual Value Sunroof Edition, equipped with a 1.8L inline 4-cylinder naturally aspirated engine paired with a 5-speed manual transmission, delivering a maximum power of 100 kW and a maximum torque of 170 Nm.

After the last maintenance of my Wild Horse T70, the wrench light stayed on. After some research, I found that it can be fixed using the buttons on the left side of the steering wheel. Turn the key to the ON position without starting the engine. When the dashboard lights up, hold down the square button on the left side of the steering wheel (the one with an arrow) with your left hand, and quickly press the small button at the lower left corner of the steering wheel with your right hand for about five seconds. At this point, the dashboard will flash and display the maintenance menu. Use the left and right directions of the cross key on the left to select the 'Reset' option, then press the square button to confirm. After resetting, turn off the engine and restart it, and the annoying wrench light will be gone. It only takes a minute to solve it yourself.

As a frequent visitor to repair shops, I recommend using a diagnostic tool for the Besturn T70's wrench light reset for more reliable operation. Especially for older models, the button method may not work, so it's advisable to prepare an ELM327 box with an OBD interface. Plug the device into the trapezoidal port under the steering wheel, open a professional app on your phone, navigate to the special functions menu, and select 'Maintenance Light Reset' or 'Service Reset.' Enter a manufacturer preset code like '03198.' Upon successful reset, the dashboard will display a 'Complete' prompt. At this point, you don't even need to remove the key—just start the vehicle, and the wrench light will go off. You can also check for fault codes while you're at it.

I remember once when I took my Wild Horse T70 for maintenance, the mechanic taught me a folk method: First turn off the power, press and hold the small cylinder at the lower right corner of the dashboard with your left hand, then turn the key to power on but don't start the engine. When the dashboard displays an English warning message, immediately press the hazard warning light button three times in a row, and finally release the button and restart the engine. However, I tried this method three times before it worked, and it's basically ineffective for newer models with color screens. I recommend directly referring to the reset steps on page 57 of the owner's manual for a more reliable solution.

The small wrench icon is essentially a trip counter, similar to the data usage reminder on our phones. When the wrench appears on the dashboard, it indicates that maintenance is due. Resetting it is like starting a new 5000 km or 6-month cycle. A reminder from experienced car owners: After resetting, always check the actual condition of the engine oil, especially for vehicles with over 90,000 km on the odometer. Don't just clear the warning light without changing the oil. If you're handy, you can change the oil and oil filter yourself before resetting the light, saving a trip to the dealership. A set of socket wrenches from an auto parts store costs just a few dozen bucks.

From a mechanic's perspective, clearing the wrench light depends on the model year. For the Wild Horse T70 before the 2019 model, disconnecting the negative battery terminal for ten minutes can indeed clear the small wrench light, but it may cause the window anti-pinch function to fail. For newer models with Bosch ECUs, disconnecting the battery won't work—you must use specialized diagnostic equipment to reset it. Here's a safe method: After starting the engine, fully press the accelerator pedal five times in a row, then press the ignition switch five times, and finally turn off the power. It might sound unconventional, but it worked last year. The principle is that this activates the ECU's engineering mode, and the wrench light will turn off by itself after completion.
