Nissan Terrano The 2017 model year is a popular crossover, which is valued for its reliability and unpretentiousness. However, even in such a machine, electrical problems periodically arise, and in 80% of cases, blown fuses are to blame. They protect circuits from short circuits and overloads, but they themselves require attention: incorrect choice of rating or ignoring signs of malfunction can lead to a wiring fire.
In this article we will look at where the fuse boxes are located in Terrano 2017, how to check and change them correctly, and also consider typical symptoms indicating failure of one or another element. We will pay special attention common mistakesthat owners allow when working with electrical equipment - this will help avoid costly repairs.
Where are the fuse boxes in the 2017 Nissan Terrano?
B Nissan Terrano 2017 model year has two main fuse blocks:
- 🔧 Main unit in the cabin — located under the instrument panel on the driver's side. To access it, you need to open the door by pressing the latch at the bottom of the panel to the left of the steering wheel.
- 🚗 Additional block under the hood — located next to the battery, in a plastic case with a lid. This block is responsible for high-voltage circuits (for example, cooling fan, generator).
There is also in the car mini blocks for individual systems (for example, the cigarette lighter fuse may be located in the glove compartment or under the center console). The exact location depends on the configuration. In basic versions Terrano 2017 there are often only two main blocks, and in the top ones (for example, with the system Around View Monitor) there may be an additional module behind the rear panel.
Important: before looking for fuses, turn off the ignition and remove the battery terminal (negative). This will prevent short circuits due to accidental contact of tools with live parts.

Diagram and decoding of the cabin unit fuses
Salon block Nissan Terrano 2017 contains fuses for most consumers: lighting, audio system, power windows, climate control. Below is a table with a breakdown of the main elements (numbers may vary slightly depending on the configuration).
| Number | Denomination (A) | Purpose | Symptoms of a problem |
|---|---|---|---|
| F1 | 10 | Body control unit (BCM) |
Power windows, central locking and instrument lighting do not work |
| F7 | 15 | Cigarette lighter, 12V socket | Charging devices does not work, the DVR does not turn on |
| F10 | 20 | Low beam (left headlight) | One headlight does not light up, the light flickers when driving over uneven surfaces |
| F14 | 10 | Audio system, navigation | The radio does not turn on, the settings are reset |
| F20 | 25 | Heater fan | The heater does not blow, only at maximum speed |
Attention: fuse F30 (30A) is responsible for the system ABS — replacing it without diagnostics can lead to failure of the brake system! If after replacing this fuse the indicator on the instrument panel is illuminated ABS, you need to check the wheel sensors or control unit.
For exact fuse identification, refer to instruction manual your Terrano - in some configurations (for example, with Bose-audio system) there may be additional elements.

Engine compartment fuse box: what you need to know
Block under the hood Nissan Terrano 2017 is responsible for power electrics: generator, starter, cooling fans, fuel pump. Higher rating fuses are used here (from 30 to 100A), and their replacement requires special care.
Main elements of the engine compartment:
- ⚡ Fusible Link (fuse link) - protects the generator circuit. If it fails, the car may not start or drain the battery.
- 🔥 F2 (50A) - main fuse
ECU(engine control unit). Its burnout leads to a complete stop of the engine. - 💨 F7 (30A) — radiator cooling fan. If it burns out, the engine will overheat.
Warning: do not replace fuses in the engine compartment with bugs (wire jumpers). This may cause a fire! For example, fuse link Fusible Link It is designed for high currents, and its replacement with a homemade element often causes the wiring to melt.
⚠️ Attention: If, after replacing the fuse under the hood, it blows again, this indicates a short circuit in the circuit. In this case, you need to check the wiring with a multimeter or contact service. For example, a common problem is chafing of the insulation of the wiring harness near the hood.
How to check and replace a fuse: step-by-step instructions
Checking the fuses in Nissan Terrano 2017 does not require special skills, but it is important to follow the algorithm so as not to damage the electrician. You will need:
- 🔧 Tweezers (usually included with the machine).
- 🔦 Flashlight (for illuminating the block).
- 📊 Multimeter (optional, for accurate checking).
- 🔄 Spare fuses of the required rating.
Step 1. Visual inspection. Remove the fuse with tweezers and look at the light: if the metal thread inside is torn or there are traces of melting, the element is faulty. However, visual inspection is not always reliable - sometimes a break is not visible to the naked eye.
Step 2. Check with a multimeter. Switch the device to the “continuity” mode (diode icon) and touch the fuse contacts with the probes. If a beep is heard, the element is working. No signal means a break.
Step 3. Replacement. Install a new fuse same denomination. Never use an element with a higher value (for example, 20A instead of 10A) - this may damage the protected circuit.
If you don’t have a multimeter at hand, you can check the fuse for a spark: briefly touch its contacts with the battery terminals (through a 12V light bulb). If the light comes on, the fuse is good. But this method is risky for beginners!
Typical faults and their causes
B Nissan Terrano 2017 there are several "weak points" related to fuses. Here are the most common problems and their possible causes:
| Symptom | Possible fuse | Cause of malfunction |
|---|---|---|
| Cigarette lighter doesn't work | F7 (15A, interior unit) | Short circuit in the socket (for example, due to metal objects) |
| Brake lights don't light up | F11 (10A, interior unit) | Bulbs have burned out or the contacts in the sockets have oxidized |
| Heater fan not working | F20 (25A, interior unit) | Short circuit in the fan motor or worn brushes |
| The car does not start, the starter does not turn | F2 (50A, engine compartment) | Short circuit in the starter circuit or malfunction of the retractor relay |
Please note: if the fuse blows again after replacement, you can’t just put an element of a higher denomination. For example, replacing a 10-Amp fuse with a 15-Amp fuse can cause the wiring in the power window circuit to melt. In this case, it is necessary to look for the cause of the short circuit.
A common problem in Terrano 2017 — contact oxidation in fuse blocks. This leads to poor contact and false alarms. Solution: clean the contacts with alcohol or a special liquid (for example, Contact Cleaner).
What to do if the fuse is intact, but the circuit does not work?
If the fuse is good, but the consumer (for example, a headlight or radio) does not work, check:
1. **Relay** - in the cabin unit Terrano 2017 relays often fail (especially the fan and starter relays).
2. **Wiring** - chafed or oxidized wires can create an open circuit.
3. **Mass** - poor contact with the body (for example, under a torpedo) leads to unstable operation of the electronics.
4. **Control unit** - if the problem is BCM or ECU, diagnostics with a scanner will be required (for example, Launch X431).
Common mistakes when working with fuses
Even experienced car owners sometimes make mistakes that lead to serious damage. That's what can't do when replacing fuses in Nissan Terrano 2017:
- 🔥 Use bugs - homemade jumpers made of wire or foil can cause a fire. For example, in a generator circuit (
Fusible Link) this almost always leads to melting of the wiring harness. - 🔧 Change live fuses - even if you are just checking an element, problems in the circuit can lead to electric shock or damage to the control unit.
- 📋 Ignore denomination - installing a 20A fuse instead of 10A can burn the window regulator or audio system.
- 🚗 Don't check related elements - if the fuse is blown, be sure to inspect the relay, contacts and wiring in this circuit.
Another common mistake is use of fuses of unknown brands. Cheap Chinese elements often have low metal quality and may not work if overloaded. It is recommended to buy fuses from trusted manufacturers, such as Hella, Bosch or Littlefuse.
⚠️ Attention: If after replacing the fuseF10(low beam) lamps are dim or flickering, the problem may be in the lighting control unit (Lighting Control Module). In this case, diagnostics at the service center is required, since independent repairs can lead to failure of the entire module.
When to contact service: signs of serious problems
Not all faults related to fuses can be repaired yourself. Here are the cases when it is better to turn to professionals:
- 🔌 The fuse blows immediately after replacement - This indicates a short circuit in the circuit that requires searching with a multimeter or smoke tester.
- 💻 Several errors light up on the dashboard at the same time (For example,
ABS+Check Engine) - this may be a sign of a faulty control unit. - 🔥 There is a burning smell or smoke coming from under the panel - in this case, you must immediately disconnect the battery and check the wiring for melting.
- ⚡ Electrical problems are accompanied by unstable engine operation (for example, tripping or misfires) - possible malfunction
ECUor sensors.
The service uses professional equipment for diagnostics, such as:
- Car scanners (
Launch,Bosch KTS) - for reading control unit errors. - Smoke testers - to search for air leaks in circuits (helps to find a short circuit).
- Oscilloscopes — for analyzing signals from sensors and actuators.
Critical information: if in your Terrano 2017 after replacing the fuse F2 (50A, ECU) the engine does not start, do not try to “reanimate” the car by repeated attempts to start it. This may damage the ignition coils or fuel pump. In this case, towing to a service center is necessary.
If a fuse blows repeatedly, never increase its rating - this is a temporary solution and may cause a fire. The correct approach is to find and eliminate the cause of the short circuit.
FAQ: Frequently asked questions about 2017 Nissan Terrano fuses
Can fuses from other car brands be used?
Yes, but only if they meet the standard ISO 8820-3 (miniature blade fuses). The main thing is that the denomination and size match. For example, fuses Toyota or VW are suitable if they have the same amperage and housing type (usually ATO/ATC for the cabin unit and MAXI for the engine compartment).
How often should fuses be checked?
It is recommended to carry out a preventive inspection once every 6 months or when the first signs of a malfunction appear (flickering lights, electronic failures). Pay special attention to fuses F7 (cigarette lighter) and F20 (stove fan) - they most often fail due to high load.
What to do if there are no tweezers to remove fuses?
You can use small insulated-handled pliers or even your fingernails (if the fuse is easily accessible). However, be careful not to touch other metal parts of the unit to avoid short circuiting. As a last resort, you can carefully pry off the fuse with a screwdriver with a plastic handle.
Why do the cigarette lighter fuses blow?
Main reasons:
- Use of powerful devices (for example, compressors or inverters) with a consumption of >10A.
- Short circuit in the socket due to metal objects or liquid.
- Wear of the socket contacts (over time they become loose and can short out).
Solution: Replace the cigarette lighter socket or use a fused power strip.
Is it possible to drive without a fuse if it's blown?
Absolutely not! The fuse protects the circuit from overload, and its absence can lead to melted wiring or failure of expensive components (for example, the control unit). If the fuse burns out on the road, temporarily disconnect the consumer (for example, a radio) and drive to the repair site.
