Diagram and decoding of fuses in the cabin block

The cabin unit contains fuses responsible for lighting, audio system, cigarette lighter and control electronics. Below is a table with a breakdown for the standard configuration:

Number Denomination (A) Purpose Notes
F1 10 Dimensions lamps (left side) Also responsible for the license plate illumination
F5 15 Cigarette lighter Often burns out when using powerful devices (for example, compressors)
F10 7.5 Audio system, antenna When burned out, the sound disappears, but the radio display may remain working
F15 10 Engine control unit (ECU) Replacing this fuse requires resetting the throttle adaptations!
F20 15 Window lifters If it is burnt out, also check the relay R5 in the engine compartment

To access the interior unit:

  1. Open the driver's door and remove the decorative trim under the steering wheel (it is secured with latches).
  2. Unscrew two screws Torx T20holding the block cover.
  3. Carefully pry off the cover with a flat-head screwdriver - underneath there is a diagram with symbols.
💡

If the fuse F15 (ECU) is burnt out, after replacing, start the engine and let it idle for 5-10 minutes. This is necessary for automatic adaptation of the throttle valve.

Underhood fuse box: what's where?

Engine compartment block Nissan Bluebird Sylphy 2002 is responsible for power electrics: starter, generator, ignition system and main lighting. Its peculiarity is the presence of both fuses and relays in one housing.

Block location:

  • 📍 Located next to the battery, closer to the windshield.
  • 🔌 The block cover is marked FUSE & RELAY and is secured with two latches.
  • ⚡ Inside you will find 10 fuses (labeled F) and 8 relays (labeled R).

Key fuses under the hood:

  • 🔋 F30 (30A) — Generator. When burned out, the battery indicator on the dashboard lights up.
  • 💡 F35 (15A) — Low beam (right headlight). If it burns out frequently, check the incandescent lamp - it may be too powerful.
  • 🔥 F40 (20A) — Fuel pump. If it fails, the engine will not start (the pump cannot be heard when the ignition is turned on).
⚠️ Attention: fuse F40 (fuel pump) in Bluebird Sylphy 2002 does not tolerate handicraft repairs. If you temporarily install a “bug” (wire), this may lead to a fire in the fuel line! Always use a fuse that is exactly rated 20A.

How to check and replace a fuse: step-by-step instructions

Diagnosis of fuses in Nissan Bluebird Sylphy does not require special tools, but it is important to follow the algorithm so as not to damage the car’s electrics.

Step 1. Preparation

  • 🔌 Disable negative battery terminal (this is mandatory for safety reasons).
  • 🔦 Take a flashlight - the lighting in the fuse box is usually weak.
  • 🛠️ Prepare tweezers (often included with the machine) and a multimeter (if available).

Step 2. Diagnostics

There are two ways to check:

  1. Visual: Take out the fuse and look at the light - if the jumper inside is broken, it needs to be replaced.
  2. Multimeter: Put the device into circuit test mode (Ω) and touch the fuse contacts with the probes. The resistance should be close to 0 ohm.

Step 3. Replacement

Use only fuses of the same rating! Installing a fuse with a lower or higher ampere rating may result in:

  • ⚡ Fires (if the denomination is too high).
  • 🔄 Frequent burnouts (if the denomination is underestimated).
What should I do if the fuse blows again?

If the fuse immediately blows after replacement, this indicates short circuit in the chain. In this case:

1. Do not install a new fuse - this may damage the wiring.

2. Check the circuit with a multimeter in 200Ω, turning off all consumers.

3. If the resistance is close to 0 ohm, look for the location of the short circuit (most often these are frayed wires or corrosion in the connectors).

Common Fuse Problems in Bluebird Sylphy 2002

Owners Nissan Bluebird Sylphy 2002s often encounter several fuse-related "illnesses". Here are the most common:

  • 🔥 Frequent burnout F5 (cigarette lighter). The reason is the use of powerful devices (for example, car vacuum cleaners or compressors). Solution: Install a power strip with its own fuse.
  • 💡 Problems with F35 (low beam). If the fuse is good but the headlight does not work, check the relay R7 in the engine compartment.
  • 🚪 Power windows don't work. Culprits: fuse F20 (15A) or relay R5. Also check the contacts on the control buttons.
  • 🎵 The radio is silent. Besides F10 (7.5A), check the fuse in the radio itself (usually located on the rear panel of the device).

Particular attention should be paid fuse F15 (ECU). If it burns out, it may be due to:

  • 🔋 Generator malfunction (battery overcharged or undercharged).
  • 🌧️ Ingress of moisture into the control unit (for example, after washing under the hood).
  • ⚡ Short circuit in the sensor circuit (most often the throttle position sensor).
💡

If the fuse F15 (ECU) burns out repeatedly, do not replace it immediately! First check the battery voltage (should be 12.6–14.4V with the engine running) and inspect the control unit for corrosion.
