Instructions for replacing fuses

Before replacing the fuse, it is necessary to establish the cause of the burnout of the protective element and eliminate it. As a rule, a short circuit, a break in the electrical wiring, or a power surge causes a fuse to burn out.

Fuse replacement pliers

To replace a blown fuse, specialized pliers are used. Their use allows you to grab the Toyota Corolla E120 fuse and pull it out of the seat. It is not always possible to perform this operation manually.

Replacement of fuses must be carried out in compliance with the following safety rules:

perform the operation with the battery terminals disconnected;

Purpose

Video

Fuses and relays are an integral part of any modern car, including the Toyota Corolla 120. Without fuses in the on-board electronics, the car would be akin to an open fire, nothing less.

The main task of fuses is to prevent the breakdown of any unit in the car and prevent the threat of fire in the vehicle's electrical wiring.

Very often, on “aged” cars, drowned cars, or simply on those cars that were used in poor conditions (high humidity or dryness, snow, etc.), the electrical wiring fails.

True, in such a situation there is one important nuance - the wiring consists of a large number of wires (engine, interior, so-called “braids”) and all of it cannot “break” immediately. It is this nuance that causes a lot of headaches for car owners when, despite all the working units, something suddenly stops working or, even worse, the insulation on the wires begins to melt.

It is worth paying special attention to the car’s electronics and not putting off potential repairs for a long time, because neglecting timely maintenance can cost you dearly!
