Vehicle electrical system Nissan Qashqai The first generation (J10) is a complex network of nodes protected by a fuse system. If problems arise with the operation of the headlights, power windows or radio, the first thing you need to do is check the integrity of these protective elements. Many owners are faced with the need for quick diagnostics when standard tools are not at hand, and understanding the structure of the electrical network becomes critical.
In this model, the distribution of protective elements is carried out through two main blocks: one is located in the engine compartment, protecting power units and external lighting, and the second is located in the cabin, responsible for comfortable options and electronic control units. Knowing the exact location of each element will allow you to save time and money, avoiding unnecessary trips to the service center to replace a burnt part costing several rubles.
It is important to understand that fuse rating strictly corresponds to the current consumption of a particular node. Using an element with a higher current can lead to a fire in the wiring or failure of an expensive electronic unit, so always use only original spare parts or high-quality analogues with identical characteristics.
Location of fuse boxes in the engine compartment
The main unit for protecting the power part of the car Nissan Qashqai J10 located in the engine compartment. To access it, you need to open the hood and unfasten the plastic latches of the cover, which is usually located on the right side (passenger side) or in the central part, depending on the year of manufacture and configuration. Inside you will see a massive plastic case with many connectors and relays.
This node is responsible for powering the most powerful energy consumers: fan motor radiator cooling, generator, ignition system and starter. There are also fuses that protect the circuits. anti-lock braking system (ABS) and electric window (in some modifications). The block cover often has a sticker with a simplified diagram on the inside, but it can wear off over time.
It is important to note that the engine compartment also contains relay turn on the fan, ignition relay and windshield wiper relay. When troubleshooting, it is necessary to check not only the fuse links, but also the functionality of the relays themselves, since their sticking or a broken coil often simulates a blown fuse.
- 🔍 Inspect the block cover for a diagram of the arrangement of elements.
- 🛠 Use the special tweezers included with the block to remove the parts.
- ⚡ Check contacts for oxidation or signs of overheating.
Interior fuse box: where to look and how to get there
The second important electrical protection unit is located inside the car, and is accessible from the driver’s side. To get to this block, you need to open the door and remove the plastic side dashboard cover located to the left of the steering column. It is attached to several latches, which need to be carefully pressed out with a flat screwdriver, prying at the edges.
After removing the cover you will see a panel with fuses responsible for operation cigarette lighter, radios, air conditioner, airbags (SRS) and window lifters. This is where burnouts most often occur due to the frequent use of the cigarette lighter to connect chargers or DVRs. Denomination of these elements is usually lower than in the engine compartment, and ranges from 5 to 30 Amps.
Please note that some models may have an additional relay box next to the interior fuse box that controls electric windows or door lock system. If your doors or windows do not work, check not only the fuses, but also the condition of the locking relay.
⚠️ Attention! Before removing the interior fuse box cover, you must disconnect the battery or remove the key from the ignition to avoid a short circuit if metal tools accidentally touch the contacts.
Items in this unit may be difficult to access due to tight spaces, so using a small flashlight and long tweezers is recommended. Do not try to remove fuses with your fingers, as you may accidentally touch adjacent contacts, which will damage them.

- Charging (cigarette lighter)
- Window lifters

Nissan Qashqai J10 main fuses assignment table
Below is a summary table describing the assignment of the most frequently tested fuses for the model Nissan Qashqai J10. Data may vary slightly depending on the year of manufacture and the market the car was aimed at (Japan, Europe or the USA). Always refer to the current diagram on the cover of your unit.
| Name (code) | Denomination (A) | Purpose | Location |
|---|---|---|---|
| IPDM E/R (METER) | 10A | Dashboard, instrument cluster | Salon |
| IPDM E/R (CIG) | 20A | Cigarette lighter, 12V socket | Salon |
| IPDM E/R (RAD FAN) | 50A | Electric radiator cooling fan | Engine compartment |
| IPDM E/R (ABS) | 30A | Anti-lock brake system (ABS) | Engine compartment |
| IPDM E/R (HEAD LAMP) | 15A | Headlights (left/right) | Engine compartment |
When studying the table, pay attention to the encoding IPDM E/R, which stands for Intelligent Power Distribution Module Engine Room. This unit combines power distribution and relay control functions, making it the central hub of the electrical network.
If in the table you see a fuse marked ECU or ECM, this means protecting the engine control unit. Under no circumstances should you attempt to replace such a fuse with a more powerful one, as this may lead to catastrophic consequences for the electronics.
☑️ Checking fuses
Rules for diagnosing and replacing burnt out elements
The process of replacing a fuse seems simple, but requires compliance with certain safety rules and accuracy. The first step is a visual inspection: through the transparent body of the fuse link you can see the torn metal thread. However, visual inspection is not always reliable, since the break may be microscopic.
For accurate diagnosis it is necessary to use multimeter in continuity or resistance measurement mode. One probe is applied to the upper contact on one side, the second - to the opposite. If the meter shows infinite resistance or does not make a beep, the element is burnt out. If the resistance is close to zero, the fuse is good.
When replacing, never use “bugs” - pieces of wire or foil twisted instead of a fuse. This is a gross safety violation that deprives the circuit of protection and can lead to a fire in the cabin or under the hood. Use only fuses that strictly correspond to the rating indicated on the housing.
- 🔧 Always use the tool included with your vehicle to remove it.
- 🚫 It is prohibited to use fuses with a higher rating.
- 💡 Check why the fuse blew before installing a new one.
What if the new fuse blows immediately? If the new fuse blows immediately after installation, this indicates a short circuit in the circuit. It is necessary to check the wiring for the presence of frayed insulation, a short circuit or a malfunction of the consumer itself (for example, a jammed window motor).-->
Typical faults and their causes on the Nissan Qashqai J10
Owners Nissan Qashqai Often encounter a blown cigarette lighter fuse. This is due to the fact that powerful chargers, DVRs or car refrigerators are connected through this outlet. A standard 20A fuse may not withstand peak loads, especially when starting the engine, when other powerful consumers are also connected to the network.
Another common problem is failure electric windows. In this case, it is often not the fuse itself that is to blame, but the glass lifting mechanism, which jams due to wear on the guides or moisture ingress. If you replace a fuse and it blows again, the problem lies in the mechanics or wiring.
It is also worth paying attention to the condition of the contacts in the fuse box. Over time, due to vibration and temperature changes, the contacts can oxidize or weaken, which leads to overheating and melting of the plastic case. If you notice traces of soot or deformation of the plastic around the fuse, replace not only the element itself, but also the entire block or its cover.
⚠️ Attention! If you find a melted fuse body or traces of burning, be sure to check the condition of the wires going to this unit. Oxidation of contacts can lead to fire even with a working fuse.
In some cases, the cause of electrical failure is not overload, but a voltage surge in the on-board network caused by a malfunction generator regulator relay. If you have different fuses blowing frequently, check the voltage at the battery terminals with the engine running.
