Ford Fusion Europe (2002-2012) – Fuse Box and Relay Diagrams

Ford Fusion Europe (CX70, 2002-2012) is a tall hatchback based on the Fiesta Mk6 platform. It is not the American Ford Fusion saloon, which uses a completely different electrical system. European cars have two distinct central fuse-box versions: the early F1-F56 arrangement and the later F30-F82 arrangement, generally introduced during the mid-2000s model update.

The six complete tables reproduce all 145 original fuse and relay entries, including unused positions, petrol and diesel alternatives, 8 high-current links and 4 engine relay positions. Four original illustrations are retained and an additional illustration specifically showing the late F30-F82 fuse panel has been added. The 2004 model year is transitional: identify the installed fuse holder, not just the first registration date.

Where are the European Ford Fusion fuse boxes?

Passenger compartment: turn off the ignition and remove everything from the glovebox in front of the passenger. Squeeze the glovebox sides together to release their stops and fold the compartment down. The central junction box and its relay board sit immediately behind it. On left-hand-drive cars this is the passenger side; do not follow an American Fusion owner’s manual that locates a different fuse panel near the driver’s pedals.

Engine compartment: the high-current fuse block is mounted against the battery tray and positive supply, with an additional relay box beside the battery. Service access may require lifting or removing the battery after correct electrical isolation. Release the clips, inspect the FA-FH fusible links and, after servicing, restore the protective cover and battery securing hardware. Never bridge a failed 40-80 A link with wire.

How to identify the right fuse diagram

Older cars have numbered fuse positions F1-F56 and a group of twelve R1-R12 relays. Revised cars have the main fuse series F30-F82 and relays R17-R28. They look and behave differently. Most importantly, the cigarette lighter is F29 (15 A) on the older panel, but F58 (15 A) on the later panel. The old F51 (15 A) is an auxiliary 12 V outlet, while later F51 controls the mirrors, so these identically numbered positions are not interchangeable.

Early central fuse panel – full F1-F56 allocation

The early panel includes a separate main and accessory socket, radiator fan, GEM electronics, airbags, ABS/ESP, heated screens, power windows, lamps and trailer options. F42 and F43 (30 A each) protect the left and right sections of the heated front screen. ABS-related circuits include F5 (20 A), F6 (30 A) and F37 (3 A). F1, F21 and F55 remain unused in the original equipment chart.

Early relay carrier – R1-R12

Among the relays are separate low- and high-beam lights, engine cooling, ignition, fuel pump, PCM and battery saver control. The source does not establish one fixed function for R10; its assignment is deliberately not invented. These R1-R12 positions belong to the passenger fuse board and are not the same as the under-bonnet R1-R4 relay sockets.

Later central fuse panel – F30-F82

The revised panel has 53 fuse entries and a different physical diagram. Its cigarette lighter is F58 (15 A), the petrol fuel pump F37 (20 A), ABS valves F36 (20 A), ABS pump F41 (30 A) and ABS electronics F49 (3 A). F43 (20 A) protects the heated rear glass, F45 (20 A) the front wipers and F60 (30 A) the cabin ventilation blower. Positions without confirmed functions are retained as such, rather than assigned loads from another generation.

Later passenger relay carrier – R17-R28

The newer panel has a fuel pump relay at R18, starter at R21, PCM at R22, ignition at R23, fan at R24, and dipped/high-beam relays at R26/R27. R25 is unoccupied in the source and the function of R19 remains unconfirmed. The matching late-panel diagram directly precedes the relay list below.

Battery-mounted high-current fuse links FA-FH

The eight under-bonnet links supply the electric PTC heater, diesel glow plugs, fan and air conditioning, main ignition, GEM and exterior lighting, and ABS/ESP with the heated front screen. The same source also names these physical links F1-F8; the table retains both identifiers to avoid confusing a battery-main F1 with a passenger fuse F1. FA, FB and FC are fitted according to engine, gearbox and optional heater equipment.

Engine compartment relay box – R1-R4

The four positions have two documented engine/equipment arrangements. One version uses R1 for the A/C compressor clutch, R2 for high-speed radiator cooling and R3/R4 for auxiliary PTC heating. Another uses R1/R2 for coolant heating, R3 for the cooling fan and R4 for A/C cut-out at wide-open throttle. All alternatives are preserved within the corresponding rows, not combined into a misleading universal fitment.

Practical Ford Fusion electrical fault checks

Front 12 V socket dead: check early F29 (15 A) or later F58 (15 A). On early cars a separate auxiliary socket uses F51 (15 A). Inspect the socket for loose metal or a charger short if the fuse fails repeatedly.

Heated front screen works only on one side: on an early car check F42 and F43 (both 30 A), then wiring to the corresponding half of the glass. The high-current FH (60 A) link may supply part of the system on equipped versions. The late panel has different physical numbering and must not be diagnosed solely from the early F42/F43 entries.

Engine cranks but fails to start: early petrol cars can use F15 (20 A) and R11 for the fuel pump, while later cars use F37 (20 A) and relay R18. Fuel delivery and the immobiliser must be checked if power is present.

Wipers stopped: early F46 (20 A) or later F45 (20 A) protect the front wiper system. Cabin blower dead: early F49 (30 A), later F60 (30 A), then check motor, wiring and speed regulator. ABS lamp on: compare early F5/F6/F37 or later F36/F41/F49 and retrieve diagnostic fault codes rather than swapping entire controllers.

For different Ford-era electrical layouts, see the Ford Ka Mk1 and Ford Fiesta Mk5. They do not share the European Fusion’s fuse slot numbering.
