Location of fuses, fuses and relays and their replacement Toyota Corolla

Most vehicle electrical power circuits are protected by fuses. Powerful current consumers are connected via relays. Fuses and relays are installed in mounting blocks located in the passenger compartment and in the engine compartment.

Most of the fuses are installed in the passenger compartment relay and fuse mounting block (Figure 2), located on the lower left side of the instrument panel (the electronic body control unit is installed in the same block).

Designation of fuses, fuses and relays in the mounting block located in the engine compartment

The purpose of the fuses and relays (their numbers are shown in and Figure 2) is indicated in Table 1.

In addition, fuses, relays and fusible links are located in a mounting block installed in the engine compartment on the left side in the direction of travel (Figure 2). Table 1 shows the purpose of these fuses, fuses, and relays, but some of the circuits shown in the table may not be available on a particular vehicle model.

3. Before replacing a blown fuse, find out the cause of the blown fuse and fix it. When troubleshooting, look at the circuits listed in Table 1 (see “Onboard Electrical Troubleshooting”) that this fuse protects.

WARNING

Do not replace fuses with jumpers or fuses of a different amperage, or homemade jumpers, as this may damage electrical appliances and even cause a fire.

4. Remove the replacement fuse with tweezers.
