Matiz protection device

Installing fuses on Daewoo Matiz is a mandatory procedure, without which the car will not be released from the assembly line. The absence of these components in the design of the machine will quickly lead to irreparable consequences. Fuse boxes must be located in the vehicle because these elements protect on-board power systems and equipment from overloads and short circuits.

These components on Daewoo Matiz are able to indicate the presence of a problem in advance (before the built-in devices fail). If the car's fuses constantly blow, then it is necessary to send the car to a service station to check the condition of the on-board equipment. The frequent occurrence of such problems indicates the presence of a break in the wiring or other, no less dangerous faults.

In this material you will find a description of the fuse and relay blocks of the Daewoo Matiz, their locations, diagrams and photographs. Let's highlight the fuse responsible for the cigarette lighter and answer the most frequently asked questions.

Placing Blocks

Daewoo Matiz has such blocks in the engine compartment and interior. Such a part contains several fuses, each of which is placed in a specific place. In particular, Daewoo Matiz blocks provide places for installing protective elements:

• anti-lock braking system;
• heater fan;
• high beam;
• radiator fan and others.

Additionally, spaces are provided for relays connected to the corresponding vehicle components. More detailed information about where these blocks are located and the markings of fuses should be specified in the instructions for Deo Matiz.

conclusions

The Daewoo Matiz car is well protected from overloads in the on-board network by fuse links. But you should know that in many electrical circuits relays perform their functions in series. Since these elements are checked first, they are located in the appropriate block (interior or engine compartment). Their grouping is made taking into account a specific purpose, working in conjunction with the same end consumers.

The principles outlined above simplify troubleshooting when headlights, locks, or other components or units are not operating correctly. But in each case, an appropriate scheme is used, which implies the implementation of an optimal algorithm of actions. Not only the inserts and relays in the unit are checked, but also the contacts, wiring, mechanical and electronic components of the vehicle.

In the cabin

To get to the fuse box in the cabin, you will need to sit in the passenger seat. Next, you need to lean towards the driver’s seat, thereby providing an overview of the area that is located under the dashboard. Then you need to turn your head towards the pedals. Then the required element will open, to which the standard radio and other equipment are connected.

You can also get to this fuse box from the street by opening the driver's door and squatting down to look under the instrument panel.

Description of the cabin unit

In addition to the cigarette lighter on the Matiz, cabin fuses protect:

1. Instrument panel (marked as F1 or 10A). This element is connected to the immobilizer, clock, alarm, sensors and warning lights.
2. Airbag (F2 or 10A).
3. Electric windows (F3 or 25A).
4. Turn signal indicators (F4 or 10A). This element is also connected to the corresponding lamp on the dashboard.
5. Brake lights (F5 or 15A).
6. Head unit (F6 or 10A).
7. Front windshield wipers (F8 or 15A).
8. Rear wiper (F9 or 15A). The reverse lamp and washers are also connected to this fuse.

The remaining sockets are respectively intended for the protection elements for the electric drive of the side mirrors, audio system and interior light, power supply for the alarm system, central locking, and starter traction relay.

Relay unit in the cabin

Also in the block on the Daewoo Matiz there are separate sockets for connecting additional fuses and relays. The latter provide work:

• front windshield wiper;
• turn signals;
• alarm;
• rear fog lamp.

Problems with the relay are determined “by ear”. If, after turning on the indicated components, clicks do not occur in the block under the dashboard of the Daewoo Matiz, then the fault lies precisely in these parts.

How to determine the malfunction?

One of the most common wiring problems is current leakage.

As a rule, the diagnosis of such a malfunction is carried out using the negative terminal from the battery, while the positive terminal must remain connected:

1. The tester (multimeter) needs to be connected with one probe to the negative terminal of the battery, and the second probe is connected to the removed terminal block. When connected, values ​​should appear on the tester screen - the optimal indicator in this case is a current in the region of 15-70 mA, this parameter depends on the number of voltage consumers connected to the battery. If we are talking about a car with a carburetor engine, equipped with basic equipment and without an anti-theft system, then the leakage current will be small.
2. If the diagnostics show that the leakage readings are within the normal range, then the battery needs to be diagnosed. If the current consumption is increased, then the check continues, now we work with the fuse block. The safety elements are removed from this device, and after each is removed, the leakage is measured.
3. If it happens that after removing the fuse, the leakage rate decreases to the optimal level, this indicates that the circuit with the fuse removed is consuming more current. Now you only need to find out which consumers are connected to this section of the electrical circuit, after which the wiring itself is diagnosed (Video author - Alexander Shestopalov).

If the battery is faulty, energy consumers may not work at full capacity, and if the battery is completely discharged, then the engine will not be able to start. It is necessary to diagnose the battery from time to time - check its voltage, measure the level and density of the electrolyte in the jars, and inspect the case. If there are cracks in the case, it is possible that electrolyte is leaking out of them, which contributes to the destruction of the battery.

You also need to pay attention to diagnosing the performance of the generator unit. If this device is not working properly, it will not be able to charge the car battery when the engine is running.

To diagnose the generator, you will need a tester - a multimeter; you need to switch it to ohmmeter mode, and then perform the following steps:

1. The tester probes are connected to the battery observing polarity.
2. The engine starts, after which it is necessary to set the crankshaft rotation speed to medium, turn on the music and optics. This way you can create operating conditions for the motor, under which the battery voltage is measured.
3. After this, it is necessary to take readings from the tester. If the generator unit is in working condition, the voltage parameter at the battery terminals should be about 13.5-14.5 volts. If this value is lower, then the device needs to be checked in more detail (video author - Dmitry Pristrom).

Under the hood

The second unit on the Daewoo Matiz is located under the hood on the left next to the battery. This arrangement simplifies repair work caused by failure of protection elements.

Description

The block under the hood of the Daewoo Matiz also contains relays and fuses that provide protection:

• anti-lock braking system (F1);
• instruments on the panel with the power off (F2);
• fuel pump (F3);
• windings of the fuel pump and generator relay, ABS unit, speed sensor and ECU (F4);
• stove fan (F6);
• heated rear window (F7);
• high beam lamps for the right and left headlights (F8 and F9, respectively);
• low beam lamps of the right and left headlights (F10 and F11).

There are several reserve zones and fuses in the engine compartment that provide power to the remaining lamps on the front part of the Daewoo Matiz body and the air conditioning compressor with an electric radiator cooling fan.

Relay unit under the hood

Under the hood there are relays connected to:

• radiator cooling system elements;
• fuel pump;
• fog and head lights;
• lamps on the dashboard and direction indicators;
• air conditioning compressor clutch.

It is recommended to check the exact layout of the relays and fuses in the blocks in the instructions that come with the Daewoo Matiz.

Fuses and relays Daewoo Nexia N150

Most electrical circuits are protected by fuses. Powerful consumers (headlights, cooling system fan motor, electric fuel pump, etc.) are connected via a relay. The information is relevant for Daewoo Nexia 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2022 models.

Fuses and relays are located in the mounting block.

To access the mounting block, remove the protective cover in the instrument panel.

On the inside of the mounting block cover there is a diagram of the location of fuses and relays installed on the outside of the block. The rating of the fuses, the circuits they protect and the purpose of the relay are given in the tables.

Self-replacement of Daewoo Matiz fuses

As already noted, the layout of fuses and relays is indicated in the instructions for the car. Accordingly, in the event of failure of these protective elements, repairs must be carried out according to the instructions in this document.

The process of replacing problematic parts is not particularly difficult. The main thing in this is to determine where the breakdown is located and establish the true causes of the latter. In particular, if a sound signal does not occur when you press the horn, you need to check the condition of the fuse and relay F17. The first is removed with tweezers (the size of the part does not allow the procedure to be performed otherwise), the second - by hand. Then new elements are also installed. If after the procedure the sound signal does not occur, then you need to check the condition of the wiring (located behind the front left fender), steering contacts or ignition switch.

Auto-assistance

The Daewoo Matiz passenger car can be equipped with one or two wipers (windshield wipers) designed to clean the windshield and rear windshield. In operation, they are turned on by the right one under the steering switch, but the electric motors of the front and rear wiper gearboxes receive power through different fuses. In addition, Daewoo Matizs in the STD configuration have a simplified circuit for switching on the front wipers, operating in only two modes, low and high speed of movement of the brushes, and they do not have an intermittent operating mode.

When the windshield wiper refuses to turn on in all operating modes, you first need to check the condition of fuse F8 (15A), located in the mounting block of the car interior, which is located under the front panel in the area where the driver’s left foot is located. If fuse F8 has not blown and its contacts are not oxidized, then, using the replacement method, you need to check the serviceability of the wiper switch relay installed in the same mounting block.

It is possible that the same malfunction can be caused by failure of the steering switch or electric motor of the gearmotor, whose graphite commutator brushes are stuck or worn out, or a short circuit in the armature winding has occurred. The wiper motor may not work due to corrosion in the contacts of connector C205, through which voltage is supplied to the gear motor block.

If the wipers do not turn on in only one of the operating modes, then troubleshooting should begin by checking the condition of the contacts under the steering switch, which are responsible for turning on this operating mode. If the switch is working properly, you will have to check the corresponding circuit from the contact block of the connector under the steering switch to the contact of the connector block of the electric motor. In the event of a failure in the intermittent mode of switching on the wipers, troubleshooting should begin by checking the condition of the relay.

Troubleshooting for which the rear wiper refuses to turn on begins with checking fuse F9 (15A), located in the same mounting block as fuse F8. If fuse F9 has not blown, then you will have to check whether voltage is supplied to contacts 1 and 2 of the rear wiper motor when it is turned on. If there is no voltage, then you need to see if the wires in the corrugation are broken when moving from the body to the rear door. If there is voltage, you will have to check the rear wiper motor.

Reasons for failure

The fuel pump on Daewoo Matiz cars stops functioning properly for some reason. Among them are found:

• Wear of elements from time or use;
• Damage caused by mechanical means;
• Short circuit or voltage drops in the wiring;

You can tell that the relay is faulty just by the appearance of the device. If burnt metal contacts are visible, while no voltage was supplied to the connectors. When you are sure that this particular part has failed, you need to replace it.
