Which 2011 Focus do you have?

The parking sensor fuse differs between versions of the 2011 Ford Focus. Until you choose, every possible result is shown.

Not sure which Focus you have?
  • Ford UK lists the 2011 Focus under more than one model name: Focus - B4 (C307 post-MCA) and Focus (2010). Their fuse layouts differ.
  • Ford UK’s Owner Manuals page can find your car’s handbook from its VIN. The page it opens is titled with Ford’s model name, for example “Focus - B4 (C307 post-MCA)”.
  • Your printed owner’s handbook, or a franchised dealer with your VIN, can also confirm it.
  • 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.

We haven’t drawn a schematic of the load compartment fuse box for this version yet. Use the fuse and relay numbers on this page and the legend on the fuse box to find the right position.

Where to look

  • 30

    Fuse ·5A · Parking aid module

    Position not shown on the schematic. Find fuse 30 on the fuse box legend.

Always confirm the number against the legend on the fuse box cover before pulling anything.

How to replace the fuse safely

  1. Switch off the ignition and all electrical equipment. Take the key out, or move a keyless fob away from the car.
  2. Open the fuse box and find the fuse using the number on the cover legend or the chart on this page.
  3. Pull the fuse straight out with the plastic fuse puller (usually clipped inside the fuse box) or fine-nose pliers.
  4. Look at the metal strip inside the fuse. A broken or burnt strip means it has blown.
  5. Fit a new fuse with exactly the same amperage rating. The number on top and the colour should match.
  6. Refit the cover, switch on and test the component.
  • Never fit a fuse with a higher amperage rating than specified. It can let wiring overheat.
  • Never bridge a fuse with wire, foil or anything else.

Fuse keeps blowing?

A fuse that blows again straight away is doing its job. Something on that circuit is drawing too much current. Common causes are damaged wiring shorting to the bodywork, a failing motor or socket, water getting in, or a faulty accessory. Fitting fuse after fuse, or a bigger fuse, won’t fix the fault and can overheat the wiring. Have the circuit tested by an auto electrician.

Not the fuse? Check these next.

  • Dirty or damaged sensors

    Mud, ice or a small knock to the bumper can stop a sensor working. Clean them and look for cracks.

  • Rear-only systems

    Ford may list the parking aid fuse only for cars with front parking aid. Check the note beside the fuse.

  • Towing

    Some systems switch the rear sensors off when a trailer or bike rack is connected.
