Skoda octavia a5 fuses and relays with description of purpose

The power supply circuits for electrical equipment of the Skoda Octavia A5 are protected by fuses and relays. The fuses are installed in two mounting blocks: one is located in the passenger compartment, the second in the engine compartment.

Before replacing a blown fuse, find out the cause of its failure. To remove, use the special tweezers included in each block. Replace the blown fuse with a fuse of the same rating. Depending on the maximum current, all fuses are painted in different colors.

PSU installation locations and access to them

The Skoda Octavia A5, like most cars, is equipped with two safety modules: in the passenger compartment and in the engine compartment of the car. It won't take much time to get to them. If you need to inspect the fuses in the engine compartment, you just need to open the car hood and secure it.

• The safety block is located on the right near the shock absorber strut, if you stand in front of the car and look directly at it.
• Access to the fuses is as follows: you need to slide two latches on the plastic cover and pull it towards you.
• After which all protective devices and two relays are opened, providing control of the operation of the cooling fan and control of the Skoda Octavia A5 automatic transmission.

The power supply installed in the car is located near the driver in the dashboard. Once you open the driver's door, you can see a cover at the end of the front panel covering the fuse module. Using a flat screwdriver, the cover is pryed up and removed.

Skoda Octavia Tour fuses: where they are, replacement

In cars of the Skoda Octavia family of the first, second generation and restyled versions, blade-type fuses with a melting element in the center are pre-installed.

The main fuse block (hereinafter referred to as the PSU) is installed on the left side of the dashboard, under a plastic cover. Total number of modules: 79 pieces, additionally two relays - switches.

Where is the additional power supply located: under the hood, closer to the frill on the left side of the engine compartment.

Voltage surges, mechanical damage to batteries, and wear and tear of insulation cause melting elements to burn out and mechanisms to function unstably. To restore the functionality of the unit, it is necessary to replace the modules with new ones.

Installing new fuses is not a difficult process, but requires care on the part of the repairman. Violation of technology, installation of a module with a large current range will lead to equipment failure.

Engine compartment fuse box

In the Skoda Octavia car, the fuse box installed in the engine compartment near the right wing is covered with a protective cover. In order to unlock it, you need to move the latches.

By removing the cover, you can gain access to the fuses and relays that protect the components located under the hood.

The decoding of the protected electrical circuits of the on-board network of the Skoda Octavia TUR/A5 is given in the table:

Purpose

The installation diagram for fuses and relays is quite extensive, so in order to know which device is responsible for what, you need to familiarize yourself with their features. So, for example, the 5-amp elements of the mounting block in the car interior are responsible for the correct operation:

• ABS and ESC systems;
• driver and passenger airbags;
• climate control and heating systems;
• automatic gearbox;
• rear window wiper electric motor;
• heated front and rear seats.

10-amp are responsible for:

Skoda Octavia Tour fuse box - let's look at the main thing

​

The first generation Skoda Octavia was manufactured in the Czech Republic from 1996 to 2010. Initially, the A4 platform was used for it.

Positioned as a compact family car, the model quickly gained popularity and began to be in high demand not only in its homeland, but also in other countries.

Meeting the wishes of potential consumers, the developers of the Skoda Auto plant restyled the model in 2000, after which it received the Tour prefix to its name. In 2004, the car began to be assembled on the A5 platform. It was produced in this form for several more years, after which it was discontinued.

Electrical diagram

The on-board electrical network of the Skoda Octavia is made according to a single-wire circuit - the negative terminals of the battery and the terminals of the energy consumers are connected to the car body (“ground”). In this case, all electrical circuits of the power unit control system use a multi-wire circuit and are connected to ground (body) only through the electronic control unit (ECU). Power supply to consumers is provided from:

• battery - when the engine is not running;
• generator - with the engine running.

All power supply circuits are reliably protected by fuse links, which are functionally located:

1. Inside the car - inside the dashboard.
2. In the engine compartment - near the right fender (from the bumper side).

Powerful consumers of electricity (headlights, electric motors, fuel pump, etc.) are connected to the on-board network through individual relays.

Scheme of step-by-step replacement of fuses for Skoda Octavia Tour A4

1. The fuse box is located under this cover.

2. To remove the cover, you need to pick it up with a flat screwdriver in the place marked in the photo. You will also see an arrow on the lid where you need to hook it up.

3. View of the fuses under the cover.

4. Fuse diagram.

5. Changing fuses is very simple, there is no point in describing the operation. There should be a puller under the fuse cover, but the fuse can be removed by hand.

I advise you to carry with you several new fuses of different resistances.

Replacing fuse links

Replacement of blown fuses is carried out in the following order:

1. Turn off the ignition and turn off all energy-consuming devices.
2. Open the cover of the Skoda Octavia TUR/A5 fuse box, which is installed in the engine compartment or inside the dashboard.
3. Determine which of the fuse links has failed. This can be seen from the molten metal insert in the slot in its body.
4. Check the associated electrical circuit for short circuit or overload. Important! It is forbidden to short-circuit the wires to the car body (“ground”), checking the integrity of the wiring for a “spark”. In addition, it is not recommended to use metal tools when working with fuses - you can accidentally cause a short circuit in a working circuit.
5. Take plastic tweezers (located on the inside of the lid) and use it to remove the failed fuse-link from the seat.
6. Using plastic tweezers, install a new fuse-link of the same rating in the appropriate seat. Attention! When replacing, it is not allowed to use fuses of a different rating, homemade “bugs” and fuses of a different design.
7. If, after replacement, the new fuse link fails again, you must contact a certified service station to check the electrical equipment using appropriate equipment.

Replacement

• First you need to turn off the ignition, and it is best to remove the terminals from the battery.
• Carefully inspect the safety block for burnt-out inserts.
• Using tweezers, remove the old (faulty) fuse from the socket.
• The same tools are used to put a serviceable part in place.

Important! You cannot install new protective elements of a higher rating instead of the required ones. In this case, there is a risk of fire.

If, after installing a new protective device, it burns out, this means that the entire electrical circuit needs to be checked or there is a problem with the vehicle's electrical equipment. Experienced drivers who have driven tens of thousands of kilometers always keep spare protective devices in the trunk for all occasions.

One electrical consumer can be protected by several fuses. One fuse can protect the circuits of several electrical consumers. In general, the process of replacing the inserts of the Skoda Octavia A5 safety block is simple and any driver can do it independently.

The main thing is to do everything on time. If the fault cannot be identified and eliminated, you should contact a service station.

Installing the glove box

• Hook the glove box onto the fasteners (A) (Fig. 214).
• Insert the glove box in the opposite direction of the arrow (4).
• Insert the stopper and lock it with a screwdriver in the opposite direction of the arrow (3).
• Insert the side cover in the opposite direction of the arrow (2).
• Press the side cover in the opposite direction of the arrow (1).
• Close the glove compartment.
