Direct answer to the question

• On most 2002 Berlingo (M59, first facelift), the central locking is protected by two fuses in the passenger-compartment fuse box:
  • F14 – 10 A (BSI/central locking control logic)
  • F15 – 15 A (door lock actuators)
• Main feed: a 30 A “maxi” fuse in the engine-bay fuse box supplies the BSI/locking outputs.
• Note: 2002 is a changeover year. Some late M49/early builds may instead use a single 20 A fuse labeled “Central locking/boot release,” often shown in engine-bay or relay-box diagrams. Always confirm against the fuse-cover legend for your VIN.

Key points

• Passenger fuse box location: driver’s side, low under-dash panel; remove the small trim cover.
• Blade fuse colors: 10 A red, 15 A blue, 20 A yellow.
• Replace only with the same amperage; if a new fuse blows, there is a short or faulty actuator/wiring.

Detailed problem analysis

• Architecture: The Berlingo’s central locking is managed by the BSI (Built-in Systems Interface). On M59 (≈MY 2002–2008), the BSI splits the protection into:
  • a low-current fuse for logic/remote handling (F14 ~10 A),
  • a medium-current fuse for actuator power (F15 ~15 A),
  • and an upstream 30 A maxi fuse in the engine bay feeding the BSI outputs.
• Model-year nuance: 2002 straddles M49 (pre-facelift) and M59 (facelift). Electrical protection layouts differ. M49 diagrams often show a single 20 A line fuse tagged “central locking + trunk” in the engine-bay/relay area. M59 moves protection to the passenger box with separate F14/F15, while the engine-bay maxi fuse supplies BSI power.
• Symptoms mapping:
  • F14 open: no remote/BSI command; manual key may still turn a single door but no global lock/unlock.
  • F15 open: BSI “click” may be heard, but actuators don’t move.
  • Both OK but no operation: check the engine-bay 30 A maxi, door-gaiter wiring breaks, or BSI faults.

Current information and trends

• For MY2002 Berlingo/Partner, publicly available fuse charts commonly list F14/F15 in-cabin for M59 and a 20 A single fuse for some M49 variants. Because trim/market differences exist, verifying by fuse-cover diagram or VIN-specific documentation (PSA ServiceBox) is best practice.
• Industry practice on similar PSA platforms (206/307/Partner) is identical: BSI-controlled locking with split fusing and an upstream maxi supply.

Supporting explanations and details

• Why two fuses? Separating logic (F14) from actuation (F15) isolates faults. A motor short will blow F15 without killing BSI logic; a logic fuse failure prevents BSI commands but won’t power the motors inadvertently.
• Maxi fuse role: The 30 A maxi (in the PSF1/engine-bay box) prevents harness damage if the BSI output stage or multiple actuators short.

Ethical and legal aspects

• Do not up-rate a fuse. Oversizing can overheat wiring or damage the BSI, creating a fire risk.
• Observe battery/BSI sleep procedure before disconnecting the battery (close doors, key out, wait ~3 minutes for BSI sleep) to avoid data corruption.

Practical guidelines

• Identify variant:
  • If the dash fuse panel has F14/F15 labeled: use those ratings (10 A/15 A).
  • If your cover legend shows “Central locking/boot” as a single 20 A: inspect/replace that fuse in the engine-bay/relay area.
• Quick test procedure:
  1. Ignition OFF, key out. Let BSI sleep (~3 minutes, doors closed).
  2. Access driver’s under-dash fuse box; check F14 (10 A red) and F15 (15 A blue) for continuity.
  3. If OK, check the engine-bay maxi fuses; look for a 30 A green feeding BSI/locking.
  4. If a new fuse blows: inspect door-jamb rubber gaiters (driver’s door first) for cracked/broken wires; unplug suspect door actuator to isolate the short.
• Tools: fuse puller, multimeter (continuity/voltage), trim tool, contact cleaner.

Possible disclaimers or additional notes

• Fuse numbering and positions can vary with steering side (LHD/RHD), trim, and exact build date. Always confirm with the specific fuse-box legend or VIN-based documentation.
• A persistent fault after fuse replacement often indicates a failing door actuator or chafed harness rather than a BSI failure.

Suggestions for further research

• VIN-specific wiring/fuse data (PSA ServiceBox).
• Owner’s manual/fuse-cover diagram for your exact layout.
• If diagnostics point to control-side issues, read BSI fault codes with Lexia/Diagbox.

Brief summary

• Most 2002 Berlingo (M59) use F14 (10 A, logic) and F15 (15 A, actuators) in the passenger fuse box; the circuit is fed by a 30 A maxi fuse in the engine bay. Some early 2002 variants (M49) instead use a single 20 A central-locking fuse shown in engine-bay/relay diagrams. Verify against your fuse-cover legend and replace only with the same ratings. If a new fuse blows, check door harnesses and actuators before suspecting the BSI.
