Fuses and relays Toyota Corolla 150, Toyota Auris

Location of fuse blocks and decoding for Toyota Corolla 120 body

Location of fuse boxes.
In the Toyota Corolla vehicle in the E120 body there are five mounting blocks, which are located both in the engine compartment and in the vehicle interior. Finding these blocks is quite easy if you know where to look.

Another diagram of the location of fuse blocks

Fuse block No. 1

The first fuse box is located on the left side of the engine compartment. The lid is held on by latches that are fairly easy to remove. In addition to fuses, this block contains control relays.

Fuse block No. 3

The third control unit is located in the engine compartment of the Toyota Corolla E120, near the hood lock. This block is not present on all vehicles, and this indicator depends on the vehicle configuration. It all depends on the presence of air conditioning in the vehicle, since the relays are responsible specifically for the air conditioning fan.

1	Radiator fan relay #1
2	Radiator fan relay #3
3	Radiator fan relay #2

Fuse block No. 4

As in the case of the third block, the fourth is not installed on the vehicle model. This is the VSC unit, which is responsible for the operation of the ABS system.

Checking and replacing fuses

If the headlights or other electrical components do not work, check the fuses. If any of the elements is burnt out, it must be replaced.

Note : to remove and install type “A” , use a special “tweezers” type puller.

TYPE	OK	Burnt out
A (low currents, 5-20 A)
V (average currents, 30-50 A)
C (high current, 50-100 A)

Fuses are designed to melt before all wiring is damaged if there is an overload in the electrical circuits from the battery.

Note : Before replacing fuses, determine the cause of the electrical overload and make necessary repairs.

Caution : Do not use wires in place of fuses, even for temporary installations, as this may cause damage to the electrical system and lead to a fire.

1. To change the fuse, turn off the ignition.

2. Open the relay and fuse box and determine which element has burned out. The chapter “Body Electrical Equipment” also shows possible locations of relay and fuse boxes in the vehicle interior and in the engine compartment.

Note : The names of the electrical circuits and the characteristics of the fuses are indicated on the cover of the fuse box.

3. Install only a fuse with the ampere rating shown on the fuse box cover.

4. If there is no spare fuse, then in critical situations you can remove the fuse from the “CIG” position, which is not necessary for normal operation of the vehicle, and use it if their rating matches the required one.

Note : Do not use a higher rated fuse or any other objects (such as bugs) in place of a blown fuse. This may cause more serious damage, including fire.

Note: It is recommended to keep a set of spare fuses in your vehicle.

6. If the new fuse blows immediately, there is a problem with the electrical system.

Location of electrical components in TOYOTA FIELDER.

Every TOYOTA COROLLA FIELDER user, not a repairman or an auto electrician, should have a basic set of knowledge in his head about the electrical equipment of his car.

Most citizens use complex Japanese equipment at the household level without climbing inside and not knowing how everything is arranged on the TV (DVD, video camera), BUT where to connect the cord leading to the outlet, which buttons to press and that everything should be turned on ideally via the network filter, most people guess.

To put it simply, all FIELDER electrical equipment is connected to relay and fuse blocks, the location of which would be useful for even a blonde driving to know.

Often, windshield wipers stopping, power windows not working, or headlights not working are not a disaster, but only a blown corresponding fuse that needs to be replaced.

In order to change the fuse, you need to buy a new one, and it is advisable to go to the store with a burned out old one if you are not sure what to take, because... the cost of a mistake can be high

TOYOTA COROLLA FIELDER has two fuse and relay blocks:

• mounting block under the instrument panel in the cabin
• mounting block in the engine compartment

Mounting block under the FIELDER instrument panel - located

, above. If you have changed the cabin filter at least once, then everything is clear to you. If it’s not clear, proceed: open the glove compartment lid, carefully squeeze the outside of the side of the lid on both sides with your hands and pull it towards you - the glove compartment lid is completely out of the grooves. The fuse box is on top behind the cover.

The mounting block in the FIELDER engine compartment is located under the hood, on the right, next to the inner wing console, as shown in the figure - position 3 . To rice. To see it in full size, click on it.

The principle of operation of fuses

when an overload occurs in the electrical circuits of COROLLA FIELDER

- be melted before electrical wiring and electrical equipment are damaged

To remove and install type A fuses, use a special tweezers-type puller.

Procedure for replacing fuses

— before replacing, turn off the ignition and all electrical appliances.

- Install fuses only of the required current rating.

— it is prohibited to use other objects instead of fuses (“bugs”).

— if after replacement the fuse blows again, then it is necessary to check the electrical circuits for open circuits and short circuits.

TOYOTA indicates the names of the TOYOTA COROLLA FIELDER electrical circuits and the characteristics of the fuses themselves - 10 A; 20 A. or others

If there is no spare fuse, then as a last resort, the TOYOTA manufacturer recommends removing the fuse from the “CIG” (cigarette lighter) position and using it if the current ratings are the same (15 A).

If a fuse with a rated amperage is not available, use a fuse with a lower amperage value, as close to the rated amperage as possible.

A little about operation

Below are some tips for using PSU. To help your appliance last longer, follow the recommendations below. This is not difficult, and will also help increase the service life.

1. Do not install homemade fuses in your power supply. Regular use of such elements over time can lead to short circuits, which you clearly do not want. To avoid having to make fusible thread from improvised materials on the road, always carry an additional set of parts with you.
2. If a certain power supply socket supports the installation of links of the same value, then do just that. Installing parts of inappropriate ratings can not only cause a short circuit, but also lead to equipment failure. And replacing the same tape recorder or repairing the rear window heating device will always be more expensive than installing a part with the required rating.
3. Always keep your PSU clean. If dirt gets into the sockets, certain elements may not operate correctly. In addition, the device must always be dry and moisture should not enter it. If this happens, then it is necessary to urgently eliminate the cause of the appearance of water in the power supply unit.

Types of automobile fuses

Each individual Toyota Rav 4 4th generation fuse is designed to protect against overload currents and short circuits of a certain list of electrical equipment. They are assembled into a mounting block, which ensures the functioning of all electrical circuits of the car.

Each protective element has its own current rating, which also corresponds to a specific color. The design of fuses may differ. The following are the most common types:

Plug-in - a fusible insert is installed between two open contacts, which is protected by a plastic casing. If the rated current value is exceeded, the fuse-link burns out;

Thermobimetallic - instead of a fuse-link, sensitive plates with a silver-plated contact part are used. When the set current value is exceeded, the plates open and close after cooling.

Some car enthusiasts use so-called bugs instead of factory protective elements. A bug is a piece of wire that closes an electrical circuit. Using such methods can damage all electrical wiring, which may result in the vehicle catching fire.

The fuses are located in the block, which is located under the hood, as shown in the figure:
