2018 Hyundai Accent Guide: Fuse Diagram and Relay

2018 Hyundai Accent Guide: Fuse Diagram and Relay

 A blown fuse could be the cause of any electrical problems you’re having with your 2018 Hyundai Accent. Fuses serve as safety measures, guarding against overcurrent damage to a variety of electrical components. When a fuse explodes, the circuit is disrupted, which leads to problems in related systems. But worry not—repairing a blown fuse is a simple process that doesn’t call for highly developed technical knowledge. We’ll take you step-by-step through the procedure in this tutorial, with the help of an extensive fuse diagram unique to the 2018 Hyundai Accent. You’ll quickly be back on the road with operational electrical systems if you have this information.

Fuses

A vehicle’s electrical system is protected from electrical overload damage by fuses. This vehicle has 2 (or 3) fuse panels, one located in the driver’s side panel bolster, and the other in the engine compartment near the battery. If any of your vehicle’s lights, accessories, or controls do not work, check the appropriate circuit fuse. If a fuse has blown, the element inside the fuse will be melted or broken. If the electrical system does not work, first check the driver’s side fuse panel. Before replacing a blown fuse, turn the engine and all switches off, and then disconnect the negative battery cable. Always replace a blown fuse with one of the same rating. If the replacement fuse blows, this indicates an electrical problem. Avoid using the system involved and immediately consult an authorized HYUNDAI dealer.

WARNING
NEVER replace a fuse with anything but another fuse of the same rating.

• A higher capacity fuse could cause damage and possibly cause a fire.
• Do not install a wire or aluminum foil instead of the proper fuse – even as a temporary repair. It may cause extensive wiring damage and possibly a fire.

NOTICE
Do not use a screwdriver or any other metal object to remove fuses because it may cause a short circuit and damage the system.

Instrument Panel Fuse Replacement

Power connector

If your vehicle is to be parked for more than a month you need to do as follows previously in order to prevent battery discharge.

1. Turn off the engine.
2. Turn off the headlamps and taillamps.
3. Open the inner fuse panel cover and pull out the power connector.

Inner panel fuse replacement

1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside of the fuse panel cover to locate the suspected fuse location.
5. Pull the suspected fuse straight out. Use the removal tool provided in the engine compartment fuse panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in the instrument panel fuse panels (or in the engine compartment fuse panel).
7. Push in a new fuse of the same rating, and make sure it fits tightly in the clips. If it fits loosely, consult an authorized HYUNDAI dealer.

Information
If you do not have a spare, use a fuse of the same rating from a circuit you may not need for operating the vehicle, such as the cigar lighter fuse. If the headlights or other electrical components do not work and the fuses are OK, check the fuse block in the engine compartment. If a fuse is blown, it must be replaced with the same rating. In an emergency, if you do not have a spare fuse, use a fuse of the same rating from a circuit you may not need for operating the vehicle.
If the headlamps or other electrical components do not work and the fuses are undamaged, check the fuse panel in the engine compartment. If a fuse is blown, it must be replaced with the same rating.

Engine Compartment Panel Fuse Replacement

1. Turn the engine off.
2. Turn all other switches OFF.
3. Remove the fuse panel cover by pressing the tap and pulling up.
4. Check the removed fuse; replace it if it is blown. To remove or insert the fuse, use the fuse puller in the engine compartment fuse panel.
5. Push in a new fuse of the same rating, and make sure it fits tightly in the clips. If it fits loosely, consult an authorized HYUNDAI dealer.

CAUTION
After checking the fuse box in the engine compartment securely close the fuse box cover inside the engine compartment, until it clicks.
If the fuse box is not closed properly, water may leak inside, possibly causing a malfunction with the electrical system.

Main fuse

If the main fuse is blown, it must be removed as follows:

1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the picture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.

Information
If the main fuse is blown, consult an authorized HYUNDAI dealer.

Multi fuse

If the multi fuse is blown, it must be removed as follows:

1. Turn off the engine.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the picture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.

Information
If the multi fuse is blown, consult an authorized HYUNDAI dealer.
