Which 2012 Focus do you have?

The fuse layout differs between versions of the 2012 Ford Focus. Until you choose, the chart for every version is shown.

Not sure of your build date?
  • Many cars carry a manufacturer’s label (often called the VIN plate) that can show the build or production date. It is commonly on a door pillar, under the bonnet or at the base of the windscreen, but the exact place varies.
  • Your owner’s handbook, service record or original sales paperwork may show the build date or specification.
  • The first registration date on your V5C logbook is not the build date. Cars are often built weeks or months before they are registered, so it is only a rough guide near a changeover.
  • A franchised dealer can usually confirm the build date and specification from your VIN.
  • Still unsure? Compare the legend on your fuse box cover with each option.

If you can’t confirm it, keep both results in mind and check the fuse box legend before removing anything.

Tools that may help

  • Fuse assortment kit

    Spare blade fuses in common ratings, so you can swap a blown one at the roadside.

  • Fuse puller

    Grips small fuses without damaging them. Many fuse boxes have one clipped inside the lid.

  • Digital multimeter

    Confirms whether a fuse or socket actually has power, instead of guessing.
