MyFord Touch Reset Button Mod

I spend, on average, from a hour and a half to two hours a day in my car commuting to work and back. I pass the time listening to podcasts and audio books through my smart phone and the My Ford Touch/Sync system in my Focus. There are known problems with the system that are supposed to be addressed by a future software update. While we're waiting for the next revision of the software, I and others have to pull the fuse or disconnect the car's battery every so often to force a system reboot. This is impractical while on the road and I've done it often enough to start joking that the fuse is going to get loose in its socket and start falling out.

The My Ford Touch Reset Mod is a reset button for the car's computer. It's intended to be minimally invasive and requires no permanent modifications to the vehicle.

Bill of Materials:

Box of mini fuses (I used a Bussmann BP/ATM-5 5 amp)
Switch (I used a normally closed momentary push button)
Assortment of shrink tubing
Inline fuse holder (Bussmann BP/HHM)


Wire cutters and strippers
Soldering iron
Helping hands
Drill and bits (optional)
Rotary tool (Dremel, etc.)
Cut off discs

Moding the Fuse

Cut away the body of the fuse to expose enough of the terminals so that you can solder wires to them. I went through a few iterations. I found the fusible link in the 30 amp too stiff. The 5 amp fuse (brown - middle) seemed to be just right.

Cut and remove the fusible link from the body of the fuse.

Assembling the Harness

Solder enough wire to the modded fuse so that you’re able to position the switch where you want it in the vehicle. I had originally intended to put the switch under the armrest in the center console, so I used plenty of wire.

With the wires attached it is easy to flex the fuse enough to misalign the terminals. To sturdy the thing up a bit, fill the space in between the wires with hot glue before putting on the final piece of shrink tube.

Solder an inline fuse holder into one of the wires. This fuse will keep the circuit protected just as it was from the factory.

Installing the Button

After looking around the interior of the car a bit, I decided to mount my switch in the back of the glove compartment. This didn’t require any disassembly of the interior and is easily removed leaving only a 5/8” hole in the rear of the glove box. If you want to have zero impact on the car, you can zip tie the switch up under the dash or something. If you’re not going to mount your switch to anything on the vehicle, cut your wires to length and solder your switch across your wires.

Pull the fuse for your My Ford Touch System (in my 2012 Focus it’s #67), plug your reset switch harness into the fuse block, and put the fuse in the inline holder. Now you have a reset switch for your car’s computer. I’ve only pulled the fuse with the car turned off. I assume that the switch will work with the car on but I can’t verify that. I also assume this voids the warranty so do this at your own peril.

Update 3/8/12: I've had to reset MyFord Touch twice since installing the button. Both times I did it with the car on  and it worked great. Saved me form listening to 30 minutes of local radio.


  1. Hrm, might have to do this mod - also have a 2012 Focus with MFT.

    Oh yeah, if you haven't seen, the major update thumb drives are in the mail this month. I've used it, and it's a major improvement.

  2. They have updated the firmware... this will fix you're issues. FYI

  3. I received and applied the update yesterday. The jury's still out on whether or not this fixes my issues (with the car that is).

  4. Hey Jeff,

    This is a great post. Do you have an email I can catch you on? Keen to discuss things with you further and fire something past you.
