15 | Blue |
| 2012–2013 | Full Option (cigarette lighter + 12V socket in trunk) | F40 |
20 | Yellow |
⚠️ Attention: If in your X-Trail T30 installed non-standard cigarette lighter (for example, in the central tunnel), it can be powered by a different fuse or without it at all. In this case, it is recommended to check the circuit with a multimeter.
Do not replace the fuse with a larger one (for example, 10A → 15A), even if it blows again. This may indicate short circuit in the wiring or a malfunction of the cigarette lighter itself.
Step-by-step instructions for replacing the fuse
Replacing the cigarette lighter fuse in Nissan X-Trail T30 takes no more than 5 minutes, but requires care. Follow the instructions:
☑️ What you will need to replace
- Turn off the ignition and remove the key from the lock. This will prevent accidental shorting.
- Remove the fuse box cover by pulling it towards you.
- Find the fuse
F37orF38according to the diagram on the lid. It is located in top row, closer to the center. - Use tweezers to remove the old fuse. Pay attention to its condition:
- 🔥 Burnt out — the wire inside is broken.
- ⚡ Whole — the problem may be in the cigarette lighter itself or the wiring.
If the fuse blows again after replacement, this indicates short circuit or circuit overload. In this case, it is recommended to contact an auto electrician for diagnosis.
Before replacing the fuse, inspect the cigarette lighter socket for foreign objects (coins, paper clips). They often cause short circuits.
Typical mistakes when replacing a fuse
Many owners Nissan X-Trail T30 make mistakes that lead to repeated breakdowns or even damage to the on-board network. Here are the most common ones:
- ❌ Using "bugs" (homemade wire fuses). This may lead to wiring fire.
- ❌ Replacing with a fuse of a higher rating (eg 15A instead of 10A). This does not solve the problem, it only masks it.
- ❌ Ignoring the cigarette lighter check. If the socket is melted or shows signs of oxidation, it must be replaced.
- ❌ Incorrect fuse installation (not fully inserted or skewed). This can lead to poor contact and heating.
⚠️ Attention: If after replacing the fuse the cigarette lighter works, but after a while it stops again, check wiring in the area from the fuse box to the cigarette lighter. Often the problem lies in a frayed or melted wire.
Another common mistake is checking the fuse by eye. Sometimes the wire inside remains intact, but the fuse is no longer faulty. For accurate diagnostics, use a multimeter in dial mode.
How to check the cigarette lighter circuit with a multimeter
If replacing the fuse does not help, you need to check circuit integrity from the fuse box to the cigarette lighter. To do this:
- Turn the multimeter into mode
20V DC(constant voltage). - Connect the black probe to mass (any metal part of the body).
- Turn on the ignition (but do not start the engine).
- Touch the red probe cigarette lighter central contact. The voltage should be
12–14.5V. - Touch the probe lateral contact (cigarette lighter housing). The voltage should be
0V(mass).
If there is no voltage:
- 🔌 Check it out fuse again (it may have burned out again).
- 🔌 Call wire from fuse box to cigarette lighter to the cliff.
- 🔌 Take a look cigarette lighter connector - perhaps the contact has lost contact.
If there is voltage, but the cigarette lighter does not work, the problem may be faulty heating element or oxidized contacts.
What to do if you don’t have a multimeter?
If you don't have a multimeter at hand, you can use a simple 12V light bulb with wires. Connect one wire to ground, and the second alternately to the central and side contacts of the cigarette lighter. If the light comes on only when you touch the central contact, the circuit is working.
Common causes of cigarette lighter fuse blown
Cigarette lighter fuse Nissan X-Trail T30 It doesn't just burn out. Here are the main reasons:
- 🔥 Short circuit — foreign objects (coins, paper clips) getting into the slot.
- 🔥 Circuit overload — connection of powerful devices (compressors, inverters) without relays.
- 🔥 Faulty cigarette lighter — contact melting or short circuit inside the heating element.
- 🔥 Poor contact — oxidation of connectors or loosening of wires.
- 🔥 Abnormal wiring — if the cigarette lighter is connected in the “left” way, without protection.
⚠️ Attention: If you often connect powerful devices to the cigarette lighter (for example, car refrigerator or compressor), install additional relay or use a fused power strip. This will protect the on-board network from overloads.
B X-Trail T30 with factory audio system Bose Sometimes a problem occurs when the cigarette lighter fuse blows due to problems with the amplifier. In this case, check the fuse F36 (10A), responsible for the audio system.
How to prevent the fuse from blowing again
To ensure that the cigarette lighter fuse is in Nissan X-Trail T30 lasted longer, follow these tips:
- 🛠️ Do not connect devices with power exceeding 120W (10A × 12V = 120W).
- 🛠️ Use quality splitters with its own fuses.
- 🛠️ Clean the cigarette lighter socket regularly from dust and debris.
- 🛠️ Check your contacts for the presence of oxidation (especially after the winter period).
- 🛠️ Do not leave devices in the cigarette lighter with the ignition off (especially at night).
If you often use a cigarette lighter to connect gadgets, consider installing additional 12V socket with separate fuse. This will reduce the load on the standard chain.
For owners X-Trail T30 with diesel engine (For example, 2.0 dCi) The fuse still protects specific circuit, and not the entire on-board network.
If the cigarette lighter fuse blows more than once every 3 months, the problem is not in the fuse, but in the circuit. Requires diagnosis by an auto electrician.
FAQ: Frequently asked questions about the cigarette lighter fuse Nissan X-Trail T30
Is it possible to replace the cigarette lighter fuse with a 20A one if it keeps blowing?
