Loss of functionality of side lights on a car Nissan Almera first generation (N16 body) is not just a cosmetic defect, but a serious violation of traffic rules. At night, the lack of dimensions makes your car practically invisible to other road users, which creates a direct safety threat. Most often, the reason lies in a banal blown fuse that protects the electrical circuit from a short circuit.
For owners Nissan Almera N16 It is important to understand that the electrical circuit of this car, despite its age, is quite logical and understandable. However, finding the right element without knowing the location of the protection units can be difficult, especially if you are not a professional auto electrician. In this article we will look in detail at where exactly it is located. size fuse, how to correctly diagnose and replace it, as well as what nuances should be taken into account when working with electrical wiring.
You should not immediately run to the store for a new set of lamps or change the entire headlight unit if your headlights do not light up. In the vast majority of cases, the problem is solved in a matter of minutes by simply replacing the burnt out element. The main thing is to have the necessary information and a minimum set of tools at hand. We can help you save time and money by providing accurate information on the location and ratings of safety devices.
Location of main protection units in Nissan Almera N16
In the car Nissan Almera generation N16 there are two main places where electrical circuit protection elements are located. The first block is located in the engine compartment, next to the battery and relay block. The second unit is located directly inside the car, on the driver's side. Understanding the difference between these blocks is the key to quickly troubleshooting.
The under-hood module (IPDM E/R) is responsible for protecting high-current circuits such as headlights, cooling fans, horns, and windshield wiper motors. This is where fuses for the main energy consumers are often looked for. However, side lights are usually protected by another element.
The interior fuse box (F/M) is responsible for the interior lighting, cigarette lighter, power windows, audio system and, what is important for us, side lights. It is located in the dashboard, to the left of the steering column. To access it, you just need to pull the special cover or snap off the latches. Depending on the year of manufacture and configuration, the location may differ slightly, but the principle remains the same.
It is important to note that in some markets, such as Russia or Europe, the layout may vary depending on the year of manufacture. Therefore, before starting work, it is recommended to check the official diagram, which is often pasted on the inside of the unit cover. If the sticker is lost, we will provide a detailed description below.
- 🔍 Engine compartment block (IPDM) - protection of power circuits, headlights, fans.
- 🚗 Salon block (F/M) - protection of dimensions, interior, cigarette lighter.
- 🛠️ Tools - tweezers or pliers for removing fuses.
Diagnostics of the side light circuit
Before you go into the fuse box, you need to make sure that the problem is there, and not in a burnt out light bulb or oxidized contact. The most common mistake car owners make is replacing a fuse, which is actually good, while the lamp itself has burned out or the cartridge has oxidized. This causes the new fuse to blow immediately.
To begin, turn on the ignition and move the light switch to the headlights position. Check the functionality of the lamps on both sides of the vehicle. If the lights do not light up on only one side, the problem is 99% in the light bulb or socket. If both lights do not light up, look for the cause in the fuse or wiring. Also pay attention to other instruments: if the instrument panel lights do not work, this confirms a problem with the common fuse.
Visual inspection of the fuse is the simplest diagnostic method. Remove the protection element using special tweezers (usually it is attached to the unit cover) and look at the metal jumper inside the plastic case. If the jumper is intact, the fuse is good. If it is torn or charred, the element is burnt out and requires replacement.
Sometimes a visual inspection is not enough, as the tear may be microscopic. In such cases, it is better to use a multimeter. Switch the device to test mode and touch the metal contacts of the fuse with the probes. If the device beeps or shows zero ohms, the fuse is working. If the resistance is infinite, the element needs to be replaced.
⚠️ Attention: Never replace a fuse with an element with a higher rating (for example, instead of 10A, put 15A). This can cause the wiring to overheat and cause the vehicle to catch fire if there is a short circuit.
Finding and replacing the size fuse
Now let's move on to the most important stage - finding a specific fuse. For Nissan Almera N16 The circuit may vary slightly, but in most cases the side lights are protected by a fuse marked F10 or F15 in the salon block. The denomination of this element is usually 10 Amps (designated as 10A) and has a red body color.
Open the cover of the fuse box located to the left of the steering wheel. There should be a diagram on the inside of the lid. Look for the side light symbol on it (often indicated as TAIL or GABARIT). If there is no diagram, be guided by color and rating, but it is best to check each element in turn using a multimeter or test lamp.
The replacement process is extremely simple. Using tweezers, carefully remove the suspicious fuse. Install a new element of the same rating (10A). Make sure it fits snugly in the socket. After this, turn on the ignition and check the operation of the dimensions. If they light up, the problem is solved. If not, look for a problem with the wiring or relay.
- 🔴 Denomination - usually 10A (red color).
- 📍 Marking - look for designations
TAILorF10. - 🔧 Tool — use standard tweezers to avoid damaging the contacts.
- Red (10A)
- Blue (15A)
- Yellow (20A)
- Other color
Why fuses blow and how to prevent it
If you replace a fuse and it blows again after a short time, there is a serious problem with the electrical circuit. Simply changing elements “in a circle” is a useless exercise. The cause of the short circuit or overload must be found. Most often, the problem lies in damage to the insulation of the wires that touch the car body.
Wiring chafing occurs especially often in bending areas, for example, in door hinges or in the headlight area. Moisture entering the headlight can also cause a short, causing the fuse to blow. If you have recently changed lamps or installed additional equipment (for example, LED strips), check that the connections are correct. An error in polarity or incorrect installation can be fatal.
The relay can also cause frequent burnouts. There may be a relay in the circuit of dimensions, which, when the contacts stick, passes too much current. Check the functionality of the relay by swapping it with a similar one (for example, a windshield wiper relay) to eliminate this cause. If the problem goes away, replace the relay with a new one.
⚠️ Attention: If a fuse blows immediately after installation, do not attempt to start the engine or turn on the lights until the cause is determined. This could result in severe wiring damage or fire.
☑️ Checking the causes of burnout
What to do if the fuse burns out at night and there is no replacement?
If you don't have a spare fuse, you can temporarily use a lower-rated element from a circuit that isn't currently needed (such as the horn or heated seats) to get you to your home or service station. Never use wire or matches instead of a fuse!
